Preface

Using this Guide

This guide is comprised of nine chapters covering both general information and reference tables.

Readers new to the HP Medical Archive system should read the first four chapters to gain an understanding of how the NMS works to help you monitor the grid. The first two chapters introduce the basic functionality and interface layout of the NMS. The next two chapters explain NMS functionality for understanding alarm monitoring and notifications, and for obtaining reports.

The remaining chapters provide references to look up specific information. Chapters 5 and 6 provide reference information on services and components. Chapter 7 is the final chapter on the NMS; a reference of alarms with troubleshooting tips.

The last two chapters deal with the Server Manager application used on the HP Medical Archive cabinet console(s).

This guide adheres to conventions for terminology to avoid confusion or misunderstanding. There are also conventions for typography to enhance readability and usefulness of the text.

Terminology

There is some room for confusion between common computer network terminology for “server” and “node” as they are used in this document.

A server is usually thought of as a piece of computing hardware that provides data services to requesting network clients; a resource pro-

viding network, computational, and storage services. Within the context of the HP Medical Archive, a server is a piece of hardw are that hosts one or more grid services.

Nodes in a network are usually defined as an independent entity with a unique network identity, running on a resource. In this text, the use of the term “node” refers to the logical entity of a building block within the HP Medical Archive; it is a server combined with a predefined set of grid services that perform one or more tasks within the grid.

The term “node” also appears within the NMS interface. In that context, it generally refers to a single grid service, regardless of how many services may be hosted on the server. See “Network and Element Terminology” on page 3 for additional information.

Numerics

Numeric values are presented in decimal unless noted otherwise. Hexadecimal values in the text are noted using the prefix “0x”; for

example: 0x3B.

Fonts

T o assist y ou in easily picking out the elements of importance, changes from the standard font are used:

• Items upon which you act are shown in bold. These include:

• Sequences of selections from the navigation tree, tabs, and

page options, such as: CN1-A-1

Architecture Overview

The HP Medical Archive architecture provides a secure, reliable, and high performance solution for the storage and distribution of very high volumes of fixed content health care data within a data center and optionally a disaster recovery (DR) site.

The term “grid computing” is inspired by the success of the interconnection of the electric power and communication network infrastructure in the late 1800s and early 1900s.

The power grid manages the available power resources and balances loads to ensure continuous operation. How and where the power originates is transparent to the consumer. During peak hours, available resources are automatically balanced and power is rerouted to where it is needed most. As demand increases, additional generating resources come online, and they are transparently utilized. Similarly, when stations go offline or get decommissioned, there are no consumer service disruptions. The grid automatically balances the available resources to changing demand; loss of a subset of resources does not result in degraded service.

Grid computing is based on the principle that access to computational resources (storage, processing power, and data) can be enhanced with high levels of reliability and scalability, analogous to obtaining electric power from the power grid. Grid storage is the application of grid computing principles to storage architecture: directories, query, resource management, and fault management.

The HP Medical Archive system is composed of multiple nodes, which form a unified archive. Each node consists of software services operating on a server that manages a limited capacity storage resource.

Within a given facility, all nodes are interconnected using standard TCP/IP networking, and communicate with local imaging modalities, PACS, and workstations. Wi de Area Network (WAN) links extend the grid, enabling off-site replication of content for disaster recovery.

The HP Medical Archive deployment relies on open standards for interoperability with external hospital systems. Exchange of clinical data with external clinical systems, including PACS, viewing workstations, and modalities, takes place over standardized network file system protocols (NFS/CIFS) or (optionally) via established imaging protocols, including DICOM.

Role of the Network Management System (NMS)

The Network Management Syste m (NMS) performs two primary functions for HP Medical Archive deployments:

• It is a monitoring system that notifies administrators of problems

when the status of key hardware or software changes (including

via e-mail or mobile phone text message, if configured).

• It is a browser-based interface making the system easily available

to multiple users for:

• Reporting status information about the grid’s hardware and

software so you can monitor and resolve grid issues.

• Creating, viewing, and printing reports on current and historic

data about each grid component based on your selection of report criteria.

• Configuring grid components and customizing the notification

settings according to your criteria.

Getting Started

Network and Element Terminology

The Network Management System views the HP Medical Archive system as having tiers, or layers of detail. From the highest (big picture) to the lowest (most granular detail) the elements are:

• Locations

• Nodes

• Services

• Components

• Attributes

Locations

The location tier views the grid as being made up of geographically separate facilities or groups of nodes. The HP Medical Archive can be deployed as a Single Site (Site A) or Single Site + DR (Site A and Site B).

Nodes

Within the context of the HP Medical Archive system, a node is a server hosting a collection of one or more grid services. Physically, a server is a computer with associated storage and network resources. Logically, a node hosts services that the NMS can monitor and manage. (The NMS itself is a service that runs on one or more servers.)

HP Medical Archive 3 T4434-96001

HPMA User Guide

Services

A service is a software module providing a set of capabilities to the HP Medical Archive system. They are discussed in detail in Chapter 5.

Each service consists of components that deliver a particular capability. Each node of the grid has a predefined set of services that it hosts.

Services are typically identified by a three letter acronym.

Components

A component within a service delivers a particular capability. Each component has a set of configurable attributes that can be monitored automatically.

Services contain one or more components. Each component contains a set of attributes.

Capabilities

Components have names defined by the software.

Attributes

The most granular level of the system is an attribute. This is a single value or property of a component in a service. Attributes are the elements that are monitored for alarm states and may be included in reports.

Every component contains a set of attributes associated with the capability it enables.

For each service and component the NMS interface presents four tabs, one for each capability:

• Overview—property information about the service or component.

You can use this capability to trace alarms, generate immediate reports (page 43), and get an overall sense of a service or component’s performance.

• Alarms—showing the status of monitored attributes and reporting

alarm histories, enabling you to trace and troubleshoot current alarms and analyze alarm histories to prevent future problems.

• Reports—for generating reports on current and historical condi-

tions of attributes to monitor and improve system performance.

4 HP Medical Archive

T4434-96001

• Configuration—to set or change service settings or alarm monitor-

ing conditions. Consult the specific service descriptions in Chapter 5 for details of the

exact information and Chapter 6 for settings available.

Software Requirements

Accessing the NMS requires access to a web browser with grid access to a well-known address (defined by your system administrator).

At this time, the only supported browser is:

• Microsoft Internet Explorer v6.0 SP2 (and above)

• JavaScript and cookies must be enabled

To view the customized and dynamic graphics used by the NMS, you must also download and install:

• Adobe SVG Viewer plug-in

The plug-in is available from the Adobe web site:

www.adobe.com/svg/viewer/install/

Getting Started

This viewer supports Scalable Vector Graphic technology (SVG); a powerful tool used for high quality graphics that are dynamically created from real-time data.

Accessing the NMS

The Network Management System (NMS) can be accessed using a supported web browser (page 5).

Both the user name and password are case sensitive.

You require a user name and password to access the system. Each system user is assigned their user name and password when first introduced to the NMS. If you did not receive a user name and password, contact your system administrator. (See “Managing User Accounts” on page 8 for more information.) To connect to the NMS interface:

1. Launch the Internet Explorer browser.

2. Open the address: https://<IP_Address>:8443/NMS where

<IP_Address> is the address of the Admin Node.

The Navigation Tree on the left side of the NMS interface displays a tree structure of the grid: the sites, cabinets, nodes, services, and components. This frame provides quick access to any element of th e grid.

Naming Conventions

The names that appear in the Navigation Tree follow the following convention:

• Locations:

• Site A—The primary site for the HP Medical Archive.

• Site B—An optional Disaster Recovery (DR) site.

• Cabinets:

• A-1 through A-10—Cabinets at the primary site.

• B-1 through B-10—Cabinets at an optional DR site.

• Nodes—Named using the following elements:

• Two or three-letter code for the type of node (such as: AN for

• A sequence number within the cabinet

• The cabinet identifier (such as B-1, A-3, and so on)

• Services—Named by the software with a three letter acronym,

T o view detailed information about an element o f the grid, click on the element’s name. The information is displayed in the Content frame of the NMS interface.

Status Indicators

The icon beside each location, cabinet, node, and service reflects the overall status of that part of the grid. (Components do not include a status indicator; they retain their normal icon and color .) If there are no alarms, the icon appears in the normal (green) state. If there is an alarm, the icon reflects the most severe alarm currently active on that branch of the tree (see Table 3 on page 33).

Content Frames

Tabs

After using the Navigation Tr ee to select a grid element, you can use the Content frame to view and report on the component’s status, alarms, and configuration.

Figure 11: Sample Overview Page

Text Color

The display of attribute values normally appears black, indicating the service is running normally (reporting to the NMS). If the text appears

blue, the service is in an unknown state (not reporting to the NMS) and

the attribute values shown are the last known values. In cases where a service is gracefully removed from the grid (offline) the last known attribute values appear in gray italics.

Immediate Reports

Beside attributes that support chart style reports (“Charts” on page 46) there is an icon indicating the format of the chart available. Selecting the icon delivers the page with the Immediate report (“Immediate Reports” on page 43) for that attribute over the past hour.

Active Alarms

If an alarm status icon (Table 3 on page 33) appears beside the attribute’s name on the Overview page, alarm monitoring for that attribute is active (see “Enabling (or Disabling) an Alarm” on page 205). The attribute status can be viewed in more detail on the Alarms tab by clicking the icon.

T4434-96001

Alarms

Interface Components

The Alarms tab provides information to trace the source of an alarm and to review an alarm’s history. This tab offers two pages of information.

• The Main page displays a table of the attributes actively being

monitored, showing their current state. Each row represents a monitored attribute and the color represents the alarm state. The table includes the attribute code, the description, and the alarm time of faults.

• The History page provides query functionality for attribute alarm

histories. Reviewing the alarm history is useful for preventing grid issues and for proactive grid maintenance. The query mechanism operates in the same fashion as custom reports (page 45).

See Chapter 3 for a full description of the alarm capability.

Reports

Configuration

The Reports tab starts with a form to create a quick report or custom query about a selected attribute. There are two kinds of reports available, chart and text, selected using the appropriate page option.

• The Chart page produces graphical data for the selected attribute.

• The Text page produces tables of data.

Both are useful tools for analyzing the system and for troubleshooting alarms. See Chapter 4 for a full des cription.

The Configuration tab offers two pages for configuring the main properties of the service or component, and for setting the alarm monitoring features.

HP Medical Archive 23 T4434-96001

HPMA User Guide

Some configuration items are not accessible to the Admin account. These can only be changed using the Vendor account.

• The Main page form allows you to change the state, label, and

notes related to an attribute.

WARNING

Changing configuration settings requires careful and deliberate planning. Some configurable elements can affect the state of your live system. Only experienced administrators should alter the device and component configuration settings.

CAUTION

Changes to the configuration are rarely needed, and should only be undertaken after consultation with HP technical support.

• The Notification page is used to change the notification details for

an attribute, as well as activating and deactivating alarms. This page gives you the ability to customize alarm settings to your specific grid needs.

CAUTION

Alarm settings are enabled as part of your i nstalla tion. Changes to alarm settings should not be made for simple convenience; this may conceal underlying problems that should be resolved. If you find an alarm is persistent, discuss the situation with HP technical support before making changes.

Configuration of alarm notifications is discussed in “Alarm Configuration” on page 201 and changes to the main configuration of services and components is discussed in Chapter 6 for each service.

Navigating Locations and Nodes

Once you have logged on to the NMS, the first displayed content is a Scalable Vector Graphic (SVG) indicating two sites. Icons indicate the actual installation of Site A and Site B. As you navigate to a site, the map shows a set of cabinets (the possible maximum of eight); again, icons above the cabinets indicate the actual installation of y our grid. At the cabinet level, a fully installed cabinet is schematically illustrated with icons beside the nodes actually installed. For a given node, a schematic image appears with icons for each service installed. Samples are shown in the following subsections.

Location and Node Maps

The grid’s geographic locations (the primary site and optional DR site) are illustrated on the map with a status icon representing actual installation. The color of the icon gives you an immediate indication of the location’s alarm state.

Interface Components

Figure 12: NMS Interface—Sample Grid Map of Locations

Clicking on an icon displays the next level (the individual location). At this level, there are eight cabinets illustrated, the maximum possible

in a single site deployment of the HP Medical Archive. (If a DR site is used, the maximum at either site is four cabinets, howe ver the illustration shows the maximum of eight.) Only installed cabinets have an icon above them.

System Status Overview

The Network Management System provides useful day-to-day information on the status of your grid. When a component of your grid is not performing within expectations however, the NMS becomes a critical assessment tool. Alarm indicators draw immediate attention to grid issues.

The NMS uses color-coding and icons for easy identification of alarm locations and levels. When you first view the NMS interface, the System Statu s icon (in the upper right corner of the page) indicates the highest alarm level on the system. You can then use the NMS tree or maps to locate the specific grid problem, assess the cause, and take quick action toward a resolution.

System Monitoring

A primary role of the NMS is to monitor grid activity and issue alarms if any attributes reach or exceed user-defined thresholds. When a tested alarm level evaluates true, that level is set.

There are six levels of alarm for each attribute; each uniquely identified (by an ID number) and individually configured. As new services are added to the grid, new alarm attribute IDs are created for it, ensuring that each alarm is uniquely associated with a specific service or component attribute and alarm level.

Each monitored attribute of each service and component is tested against the configured thresholds using the algorithm shown in Figure 15.

The attribute value is tested against each enabled setting starting from the most critical and working toward normal. The “Unknown” setting is the last one tested.

T4434-96001

Alarms

When an alarm condition is found to be true, that level is checked against the current alarm level for the attribute. If there is no change, then no further action is taken.

Figure 15: Alarm Monitoring Algorithm

Only if a new alarm level is detected is there a change in the alarm level reported. This automatically clears alarms when conditions return to the “Normal” level.

If an alarm level changes, the current alarm level is set and propagated up the network hierarchy as needed. If there is a notification e-mail address, then a brief text notification is sent. The notification is sent only at the time the alarm state enters the new level.

Notifications

Administrators can be notified if an alarm reaches a level of urgent concern. All alarms provide indicators for informational purposes that you can check on a routine basis. Urgent ones can also be configured to

HP Medical Archive 31 T4434-96001

HPMA User Guide

issue a text notification to the user-specified e-mail addresses (possibly routed to a pager or mobile phone) of system administration staff.

The NMS is pre-configured with a default set of alarms and notification settings. You can easily customize these settings to reflect your company’s network monitoring methodology.

For information on how to customize the alarm notification settings, see “Alarm Configuration” on page 201.

CAUTION

Indicators and Propagation

Alarms are generated at the attribute level of the grid. When an issue is detected, the alarm is propagated up through the grid hierarchy. The associated attribute, component, service, and node information on the NMS are all changed to reflect the alarm state. As a result, you can view the general alarm state at the grid level, then drill down through the service components to locate the specific details. (See Figure 16: “Sample Alarm Indicator Propagation” on page 34.)

Each individual service reflects the highest alarm state of its components. If more than one alarm exists on a node, the node always reflects the highest and most serious alarm level (see “Alarm Levels and Indicators” below). Locations (Site A and Site B) display the highest alarm level of the nodes on that branch.

Refer to Figure 16 on page 34 for an example. One node’s SSM indicates a minor alarm state while its LDR indicates an unknown state. That node icon displays the unknown alarm state (the higher alarm level). Another node in the same group shows a major alarm on the AMS service. The group location propagates the “unknown” alarm indicator. The color and icon of each service, node, and location reflects its highest alarm state along its branch of the Navigation Tree.

Alarm Levels and Indicators

NMS alarms are organized into a hierarchy of levels. The hierarchy reflects the seriousness of a grid issue. There are six alarm levels in the NMS interface. Each alarm level has an associated color and icon. The NMS alarms levels (from lowest to highest) are:

Offline

The “Unknown” alarm level is considered the most severe if it is enabled and detected, although it is the last level tested in the alarm monitoring algorithm (Figure 15 on page 31). Most attributes do not enable this level. It is typically used to indicate loss of connection between the NMS and a service.

Each alarm level has it s own icon and color. These icons and colors are used throughout the NMS interface to save you time when analyzing a critical grid situation. Alarm colors and icons accelerate alarm identification and resolution by making the alarm source quickly visible on the NMS interface. The System Sta tus icon in the Header frame immediately indicates the most serious alarm level of the grid. The icons on the Network Map indicate the status of each location or node. You can then follow the tree branch to the individual service to find the source of the alarm.

operation. Requires immediate attention.

Nodes display the alarm icon of the highest alarm state among their hosted services (Figure 16). Note that each service retains its unique icon, but the color changes to reflect its current alarm state. Component icons and colors, however, remain unchanged regardless of the alarm state.

Figure 16: Sample Alarm Indicator Propagation

Alarms Tab

Under the Alarms tab of each service or component, colors highlight critical alarm information (Figure 17). By default, the table rows are green to indicate a normal status. If the status of an attribute changes, an alarm row for that attribute changes to the appropriate color (Table 3 on page 33).

Figure 17: Sample Alarms Tab

Each row provides detailed information about the alarm (see Table 4 on page 36 for details). More detailed information about each attribute’s code, value, and definition can be found in Chapter 7, “Troubleshooting Alarms” on page 247.

Main Page

Once the alarm is resolved, the alarm returns to the green status to indicate that the attribute has returned to a normal state.

You can access and view alarm status at both the service and the component levels. There are two pages under the Alarms tab: Main and History. When the tab is selected, it defaults to the Main page, which provides details of the current status.

The Main page of the Alarms tab gives the current status of the selected service or component attributes. This page is an overview of each attribute’s current alarm level. You can use this page to get a quick, but detailed, sense of what may be causing a system alarm. The Main page can also be used to track the daily status of the system in order to prevent major alarms.

Analyzing Alarm Histories

Queries on the alarm history page provide valuable analytical information. You can query for data about a specific attribute or for all of the alarms that have occurred on a node over a specified period of time.

These queries are a powerful grid diagnostic tool, enabling you to identify alarm patterns and service issues. Regularly reviewing alarm patterns can resolve minor issues before they impact grid functionality. At the very least, reviewing the alarm history gives an overview of how the system is functioning and may help to prevent future alarms.

Alarm Handling

The NMS is a critical tool for responding to system alarms. When you receive an alarm notification, the NMS provides the data necessary to resolve the issue. This section provides step-by-step procedures for investigating, evaluating, and responding to alarms.

Tracing the Source of an Alarm

Tracing an alarm follows these main steps (each is expanded later in the text):

1. Trace through the network tree to the specific node generating the

alarm.

2. Use the information from the Alarms table to identify the compo-

nent and attribute causing the alarm.

3. Troubleshoot the alarm by using the lookup table in Chapter 7,

“Troubleshooting Alarms” on page 247.

Introduction to Reporting

Reports are a powerful system analysis and troubleshooting tool. The NMS can generate reports at both the service and the component level, although some individual attributes do not have reportable events. These reports provide an overview of how a system attribut e is functioning over a selected period of time. By viewing a report, you can quickly ascertain if the attribute has any issues.

Reports are also valuable to track the data flow on the grid. You can view how much data enters the grid each day, how many audit messages are being sent, and whether the data storage capacity is sufficient. You always know the state of resources on your grid.

The NMS provides a variety of report query options and displays. You generate reports with the simple click of a button or by requesting a custom report according to specific time spans. The generated report can be displayed in a graphical chart or a text table. You can then print the final report, or copy it for use in documents.

Report Types

The NMS provides three different way s to gener ate report s:

• Immediate—generated by the click of a button on the Overview

page.

• Quick—created through preset criteria selections on the Reports

page.

• Custom—a form on the Reports page enables you to specify your

requirements, providing feedback specifically customized to your needs.

Charts and Text Reports

Reports take one of two forms: chart or text. Charts present the data in a graphical view. Text reports are a simple text table with row entries for each event that an attribute reported. Both types are described in greater detail later in this chapter.

The format is determined by the page from which you select the report. Immediate reports are always charts, selected from the

Overview page. Quick and Custom reports are available from both the Reports

Accessing Reports

Reports are accessed in one of two ways:

• Immediate reports are accessed by clicking the chart icon on the

Overview tab for the service or component.

• Quick and Customized reports are accessed from a form on the

Reports tab under either the Chart page or the Text page. Under the Reports tab, each service and component has select

attributes for which reports can be generated. Individual service details in Chapter 5 indicate whether attributes are reportable. In some cases, the attributes available under the chart and the text pages differ.

Immediate Reports

Immediate reports are available on the Overview page for reportable attributes, indicated by a chart butt on at the right side of the page.

Quick Reports

To generate an immediate report:

1. Navigate to the service or component you want to report on. The

item’s Overview page appears.

2. Scroll to the attribute you w ant to chart. If reports can be generated

for the attribute, the appropriate report button is available at the far right of the attribute’s row.

3. Click on the report button. The Reports page appears and the

requested chart is displayed.

The report displays the attribute’s data over the past hour, a preset time span. To view other time ranges, or to see a wider (zoom out) or narrow (zoom in) range of time use either the Quick Reports or the custom report form.

Quick reports are available on the Reports tab, from both the Chart and Text pages.

There are six options specifying the time span for the report, ranging from the last 5 minutes to the last year. Quick reports can be generated with the selection of an attribute and then the push of a time span button.

CAUTION

Allow several minutes for charts to appear. Although the Content frame may update fairly quickly, charts can take several minutes to tabulate and form the image. Do not initiate another report request until the current one has completed.

To view other time ranges, or to see a wider (zoom out) or narrow (zoom in) range of time, modify the start and end dates in the custom report form.

Report Formats

Chart and text reports present essentially the same data in very different ways. You can use each report format to suit your specific reporting needs. Chart reports give a graphical presentation of data. T ext reports give th e basic data in a simple table with no customization options after the report has been created.

Charts

Chart reports present the data with the attribute values (vertical axis) over a specified time span (horizontal axis). The types of chart reports available are detailed below. If the numbers in the chart represent a volume portion (such as the percentage of memory being used), the area under bars is shaded. If the numbers represent exact values (such as the number of system restarts), the bars appear as a simple line with no shading.

Data for a given period may appear slightly different on charts that cover different time ranges. For example, the charted values shown in the last hour may differ when included in a chart of the last day. This is

46 HP Medical Archive

T4434-96001

Reports

an artifact of the data downsampling and “binning” that is performed prior to charting large volumes of data. These differences are normal.

If you require precise results, you can obtain the unprocessed values by using a text report. Note that text reports do not list any data during periods when the attribute was either unavailable or was unreported (indeterminate). Charts use white space or light purple shadi ng respectively to indicate these periods.

Interpreting Lines and Shading

Charts use color and shading to convey specific informat ion about th e graph.

Table 6: Chart Colors and Shading

Sample Meaning

Reported attribute values are plotted using dark green lines.

Light green shading around dark green lines indicates that the actual values in that time range vary and have been “binned” together for faster plotting. The range in light green indicates the maximum and minimum values within the “bin”. Light brown shading is used for bar graphs to indicate volumetric data.

Light purple shading indicates that the attribute value at that time was indeterminate; the attribute wa s not reporting.

Blank areas (white, no data plotted) indicate that the attribute was unavailable. The service or component was known to be offline, so no data exists for that time range.

HP Medical Archive 47 T4434-96001

HPMA User Guide

Level Graph

Level graphs are used to plot the values of an attribute that has a “unit” value (such as Local Clock Rate Error, in ppm). The changes in the value are plotted in “bins” at regular intervals over time.

Bar Graph

Bar (area) graphs are similar to level graphs but include a light brown shading below the line. These are used to plot the values of an attribute that has a “quantity” value (such as Service Load, a percentage). The changes in the value are plotted in “bins” at regular interv als over time.

48 HP Medical Archive

T4434-96001

Reports

State Graph

State graphs are similar to level grap hs but the trans itio n is discontinuous; that is, the value jumps from one state (value) to another. These are used to plot values that represent distinct states (such as a service State, that can be online, standby, or offline). The changes in the value appear as distinct horizontal lines at predefined levels on the chart.

Text Reports

Text reports present the data in a simple table with the date and time in the first column and the attribute values in the second column. They give the basic data in a simple format without any of the additional overview information provided in a chart report.

Figure 24: Sample Text Report

The Date column lists the local date and time of attribute reports. The Value column displays the attribute’s value for each report.

This detailed breakdown of data can result in very long tables. Text reports are therefore better suited to shorter, more specific time spans.

HP Medical Archive 49 T4434-96001

HPMA User Guide

Text reports support some attributes—such as changes to text attributes—that are not available in chart form.

Chart View Controls

When you generate a chart report, it may be useful to compare the results with another chart. The NMS provides the ability to view the data in a new window; to hold it while using the main interface to select other reports or views.

To see other time ranges of data, use the custom report form to select the desired range. Narrowing the time span “zooms” in on the data for detailed analysis.

Window

To capture the current view for comparison with other chart views, you can place the chart in a new window (kiosk). You may open as many of these kiosk views as you wish.

Opens a new window and displays the current view.

When you are done, use your operating system’s window close button to close these chart windows.

Overview of Services and Components

The NMS categorizes system information by the services a nd se rvice components found on each node. These services and components contain attributes that form the basis for the NMS alarm notification and report options.

This chapter provides a complete list of NMS services and components. Services are listed alphabetically.

Not all grids use every service and component listed here. Each grid uses only those services and components suited to the options purchased and the functionality required.

Services

Grid services are programs that run on the physical servers (nodes). Each delivers particular services to the grid as shown in Table 7. The NMS is used to access the critical information gathered by these services so that you can monitor the condition and performance of your grid.

By clicking on the service name in the NMS, you can view detailed data about the service and each of its component functions. The NMS provides basic functional statistics, alarm status, reporting functionality, and configuration options for each service and node.

Within a grid, the same service can be installed and used on more than one node. The settings made to a service on one node do not affect the settings on the same service installed on a different node. System-wide configurations can be made by a service technician under the Vendor account using components of the Configuration Management Node (CMN).

Service Components

Each service is composed of one or more components that manage one piece of the service’s functionality. When using the NMS, you can select a service’s component to view the attributes that the component manages. The NMS also provides alarm status, reporting functionality, and configuration options for each component.

The Type/Units column identifies the data type or units of measure. This is useful in interpreting alarm settings and the nature of reports that can be generated. If the type is “Enumerated text”, the enumerated values that the attribute can have are listed with the description of the attribute. Note that some attributes have enumerated values that can only occur under software control.

For units of “Duration” or “Bytes”, the values displayed in the NMS are scaled to a suitable unit. For example, durations scale to seconds, minutes, hours, or days; bytes scale to Kilobytes, Megabytes, or Gigabytes.

The scale of bytes displayed by the NMS uses the “natural” measure of powers of 10. For example 3 MBytes = 3 x 10

= 3,000,000 bytes. This is not the same as powers of 2 normally used for computing, where 3 MBytes = 3x220 = 3,145,728 bytes.

Services and Components

ADC—Administrative Domain Controller

The Administrative Domain Controller (ADC) authenticates the grid nodes and their connections with each other. For two nodes to connect, the ADC must have certificates for both. The ADC maintains the certificates and synchronizes this information with the other ADCs in the grid.

In general, all system nodes maintain a connection to at leas t one ADC. This ensures that the nodes are always accessing the latest certificates (which may occasionally be updated or revoked). When nodes connect they cache other nodes’ certificates, enabling systems to continue functioning with known nodes even when an ADC is unavailable. New nodes can only establish connections via an ADC.

The connection of each node lets the ADC gath er topology information. This node information includes the CPU load, the amount of available disk space (if it has storage), the supported services, and the node’s group ID (location). The grid’s LDRs, CMSs, and CLBs ask the ADC for topology information through topology queries. The ADC responds to each query with the latest information received from the grid.

Group IDs are in the form of 10X00Y, where X and Y are pre-assigned based on the site and cabinet number. For example, cabinet B-3 would have a Group ID of 102003. These are used in placing replications under business rules, to permit the grid to disperse data in the most robust and efficient manner possible within the available topology.

ADC Attributes

The ADC supports the common set of service attributes. These common service attributes appear on the Overview tab for the service.

AMS—Audit Management System

The Audit Management System (AMS) logs all audited system events to a text file on the server. The grid uses positive acknowledgement to prevent loss of audit messages. A message remains queued at a se rvice until the AMS, or an intermediate audit relay service, has acknowledged control of it.

Access to the audit log files is limited to authorized technical support staff unless you have purchased the audit option. For those with the audit option a separate document detailing access and log content is provided.

CLB—Connection Load Balancer

The Connection Load Balancer (CLB) directs incoming content to the most optimal storage service based on a variety of criteria. The CLB ranks nodes based on several factors such as availability, and system load. When the most optimal node has been chosen, the CLB establishes an outgoing connection and forwards the traffic to the chosen node.

The CLB serves as a connection pipeline between the remote entity and an LDR for DICOM.

CMN—Configuration Management Node

This service provides a mechanism to perform grid-wide configuration of connectivity and protocol features needed by all services in the grid. Viewing the attributes of this service and its components, enables you to determine:

• The File System Gateway (FSG) replication groups (see ) and the

roles each FSG is performing.

• The remote entities permitted to connect and to which capabilities

they have access

• The state and history of Grid Tasks; specially programmed opera-

tions to update or service the HP Medical Archive.

• Your Grid ID number

• Other information related to servicing your grid.

Remote Connections and Permissions

Components of this service control the list of “friends” from which connections to the grid are permitted. Each of these is allocated permission to use the HTTP or DICOM protocol, or both. Within each protocol, there are profiles that govern the permitted activities.

Access to the settings for components of this service is restricted to the V endor account. Contact HP technical support for assistance.
