Monitoring Objects in Your Managed
Environment by Using
vRealize Operations Manager 1
You can use vRealize Operations Manager to resolve problems that your customers raise, respond to alerts
that identify problems before your customers report problems, and generally monitor your environment for
problems.
When your customers experience performance problems and call you to resolve the problem, the data that
vRealize Operations Manager collects and analyzes is presented to you in graphical forms so that you can
compare and contrast objects, understand the relationship between objects, and determine the root cause of
problems.
To manage your environment as a proactive rather than reactive administrator, you monitor and respond to
alerts. A generated alert noties you when objects in your environment are experiencing problems. If you
resolve the problem based on the alert before your customers notice, then you avoid service interruptions.
You can investigate the problems that generate alerts or that result in calls by using the Analysis,
Troubleshooting, Details, and Environment tabs.
If you nd the root cause of the problem, you might be able to resolve the problem by running an action.
The actions make changes to objects in the target system, for example, the VMware vCenter Server® system,
from vRealize Operations Manager.
This chapter includes the following topics:

User Scenario: You See Problems as You Monitor the State of Your Objects on page 19
n
As you investigate your objects in the context of this scenario, vRealize Operations Manager provides
details to help you resolve the problems. You analyze the state of your environment, examine current
problems, investigate solutions, and take action to resolve the problems.
User Scenario: A User Calls With a Problem
The vice president of sales telephones the help desk reporting that her virtual machine, VPSALES4632, is
running slow. She is working on sales reports for an upcoming meeting and is running behind schedule
because of the slow performance of her virtual machine.
As a network operations engineer, you were just reviewing the morning alerts and did not see any problems
with her virtual machine, so you begin troubleshooting the problem.
Procedure
1 Search for a Specic Object on page 8
As a network operations engineer, you must locate the customer's virtual machine in
vRealize Operations Manager so that you can begin troubleshooting the reported problem.
2 Review Alerts Related to Reported Problems on page 9
To determine if the virtual machine about which the vice president of sales reported problems has
alerts that indicate the cause of the problem, you review the alerts in vRealize Operations Manager for
the object.
3 Use the Troubleshooting Tab Options to Investigate a Reported Problem on page 10
To troubleshoot problems with the VPSALES4632 virtual machine, you evaluate the symptoms,
examine time line information, consider events, and create metric charts to nd the root cause of the
problem.
Search for a Specific Object
As a network operations engineer, you must locate the customer's virtual machine in
vRealize Operations Manager so that you can begin troubleshooting the reported problem.
You use vRealize Operations Manager to monitor three vCenter Server instances with a total of 360 hosts
and 18,000 virtual machines. The easiest way to locate a particular virtual machine is to search for it.
Procedure
1 In the Search text box, located on the vRealize Operations Manager title bar, type the name of the
virtual machine.
The Search text box displays all the objects that contain the string you type in the text box. If your
customer knows that her virtual machine name contains SALES, you can type the string and the virtual
machine is included in the list.
2 Select the object in the list.
The left pane displays the object name and the related objects, including the host system and vCenter Server
instance. The main pane displays the Summary tab.
What to do next
Look for alerts related to the reported problem for the object. See “Review Alerts Related to Reported
Problems,” on page 9.
8 VMware, Inc.
Chapter 1 Monitoring Objects in Your Managed Environment by Using vRealize Operations Manager
Review Alerts Related to Reported Problems
To determine if the virtual machine about which the vice president of sales reported problems has alerts that
indicate the cause of the problem, you review the alerts in vRealize Operations Manager for the object.
Alerts on an object give you an insight into problems other than the one that the object user reports.
Prerequisites
Locate the customer's virtual machine so that you can review related alerts. See “Search for a Specic
Object,” on page 8.
Procedure
1 Click the Summary tab for the problematic object.
The Summary tab displays active alerts for the object and for any descendant objects that are classied
at the top alerts.
2 Review the top alerts for Health, Risk, and Eciency.
Top alerts are considered the primary contributors to the current state of the alert badges. Do any of
them appear to contribute to the slow response problem? For example, any ballooning or swapping
alerts, which indicates that you need to add memory to the virtual machine? Any alerts related to
memory contention, which indicates that you need to add memory to the host.
3 If the Summary tab does not include any top issues that appear to explain the reported problem, click
the Alerts tab.
The Alerts tab displays all active alerts for the current object.
4 Review the alerts for problems that are similar to or contribute to the reported problem.
a To view the active and cancelled alerts, click Status: Active to clear the lter and display active and
inactive alerts.
The cancelled alerts might provide information about the problem.
b Click the Created On column to sort the alerts so that you can locate alerts generated on or before
the time when your customer reported the problem.
c To view alerts for the ancestor objects in the same list with the alert for the virtual machine, click
the up arrow and select Host System and Cluster Compute Resources, if they are congured in
your environment.
Add these object types to the list so that you can determine if alerts among the parent objects are
contributing to the reported problem.
5 If you locate an alert that appears to explain the reported problem, click the alert name in the alerts list.
6 On the alert details Summary tab, review the triggered symptoms and recommendations to determine
if the alert indicates the root cause of the reported problem.
What to do next
If the alert appears to indicate the source of the problem, follow the recommendations and verify the
n
resolution with your customer. For an example, see “Run a Recommendation On a Datastore to Resolve
an Alert,” on page 18.
If you cannot locate the cause of the reported problem among the alerts, begin more in-depth
n
troubleshooting. See “Use the Troubleshooting Tab Options to Investigate a Reported Problem,” on
page 10.
VMware, Inc. 9
vRealize Operations Manager User Guide
Use the Troubleshooting Tab Options to Investigate a Reported Problem
To troubleshoot problems with the VPSALES4632 virtual machine, you evaluate the symptoms, examine
time line information, consider events, and create metric charts to nd the root cause of the problem.
If a review of the alerts did not help you identify the cause of the problem reported for the virtual machine,
use the Troubleshooting tabs, Symptoms, Timeline, Events, and All Metrics, to troubleshoot the history and
current state of the virtual machine.
Prerequisites
Locate the object for which the problem was reported. See “Search for a Specic Object,” on page 8.
n
Review the alerts for the virtual machine to determine if the problem is already identied and
n
recommendations made. See “Review Alerts Related to Reported Problems,” on page 9.
Procedure
1 If you are viewing the Alert Details tabs, click Virtual Machine in the left pane and select
VPSALES4632 in the lower list.
The main pane updates to the display the object Summary tab.
2 Click the Troubleshooting tab, click the Symptoms tab, and review the symptoms to determine if one
of the symptoms is related to the reported problem.
Depending on how your alerts are congured, some symptoms might be triggered but not sucient to
generate an alert.
a Review symptom names to determine if one or more symptoms are related to the reported
problem.
The Information column provides the triggering condition, trend, and current value. What are the
most common symptoms that aect response time? Do you see any symptoms related to CPU or
memory usage?
b Sort by the Created On date so that you can focus on the time frame in which your customer
reported that the problem.
c Click the Status: Active lter buon to disable the lter so that you can review active and inactive
symptoms.
Based on symptoms, you think the problem is related to CPU or memory use. But you do not know if
the problem is with the virtual machine or with the host.
3 Click the Timeline tab and review the alerts, symptoms, and change events over time that might help
you identify common trends that are contributing to the reported problem.
a To determine if other virtual machines had symptoms triggered and alerts generated at the same
time as your reported problem, click Show Peer Events.
Other virtual machine alerts are added to the time line. If you see that multiple virtual machines
triggered symptoms in the same time frame, then you can investigate ancestor objects.
b Click the Show Ancestor Events and select Host System.
The alerts and symptoms that are associated with the host on which the virtual machine is
deployed are added to the time line. Use the information to determine if a correlation exists
between the reported problem and the alerts on the host.
10 VMware, Inc.
Chapter 1 Monitoring Objects in Your Managed Environment by Using vRealize Operations Manager
4 Click the Events tab to view changes in the collected metrics for the problematic virtual machine that
could direct you toward the cause of the reported problem.
a Use the Date Controls option view event for the approximate time when your customer reported
the problem.
b Click through the Workload, Capacity, and Stress badges to determine if any events are associated
with the problem.
c Click Zoom the View and zoom in on any events or event clusters that occurred at or before the
problem was reported.
d Click Show Data Values and place the cursor over an event to view the details about the event.
The events for the selected time also appear in the data grid below the event chart.
e In the left pane, click Host System, click the host name in the list on the lower left pane, and repeat
the analysis of the host using Workload, Capacity, and Stress.
Comparing events on the virtual machine and the host, and evaluating those results, indicates that CPU
or memory issues are the likely cause of the problem.
5 If you can identify that the problem is related to, for example, CPU or memory use, click the All Metrics
tab to create your own metric charts so that you can determine whether it is one or the other, or a
combination.
a If host is still the focus, then start by working with host metrics.
b In the metric list, double-click the CPU Usage (%) and the Memory Usage (%) metrics to add them
to the workspace on the right.
c In the map, click the VPSALES4632 object.
The metric list now displays the virtual machine metrics.
d In the metric list, double-click the CPU Usage (%) and the Memory Usage (%) metrics to add them
to the workspace on the right.
e Review the host and virtual machine charts to see if you can identify a paern that indicates the
cause of the reported problem.
In this scenario, comparing the four charts reveals that CPU use is normal on both the host and the
virtual machine, and the memory use is normal on the virtual machine. However, the memory use on
the host began going consistently high three days before the reported problem on the VPSALES4632
virtual machine.
The host memory is running consistently high, aecting the response time for the virtual machines. The
number of virtual machines it is running is well within the supported amounts. The possible cause might be
too many high process applications on the virtual machines. You can move some of the virtual machines to
other hosts, distribute the workload, or power o idle virtual machines.
What to do next
In this example, you can use vRealize Operations Manager to power o virtual machines on the host so
n
that you can improve the performance of the virtual machines that are in use. See “Run Actions From
Toolbars in vRealize Operations Manager,” on page 66.
If the combination of charts that you created on the All Metrics tab are something that you might want
n
to use again, click Generate Dashboard.
If you did not resolve the problem, continue your investigation.

User Scenario: An Alert Arrives in Your Inbox
You return from lunch to nd an alert notication in your inbox. You can use vRealize Operations Manager
to investigate and resolve the alert.
As a network operations engineer, you are responsible for several hosts and their datastores and virtual
machines, and you receive emails when an alert is generated for your monitored objects. In addition to
alerting you to problems in your environment, alerts should provide viable recommendations to resolve
those problems. As you investigate this alert, you are evaluating the data to determine if one or more of the
recommendations can resolve the problem.
This scenario assumes that you congured the outbound alerts to send standard email using SMTP and that
you congured notications to send you alert notications using the standard email plug-in. When
outbound alerts and notications are congured, vRealize Operations Manager sends you messages when
an alert is generated so that you can begin responding to problems as quickly as possible.
Prerequisites
Verify that outbound alerts are congured for standard email alerts. See vRealize Operations Manager
n
Customization and Administration Guide.
Procedure
1 Respond to an Alert in Your Email on page 13
As a network operations engineer, you receive an email message from vRealize Operations Manager
with information about one of the data stores for which you are responsible. The email notication
informs you about the problem even when you are not presently working in
vRealize Operations Manager.
2 Evaluate Other Triggered Symptoms for the Aected Data Store on page 14
You determined that you need more information about the data store before you decide the best
response. As a network operations engineer, you examine the Impacted Object Symptoms tab to see
the other triggered symptoms for the data store.
3 Compare Alerts and Events Over Time in Response to a Datastore Alert on page 15
To evaluate an alert over time, compare the current alert and symptoms for the datastore to other
alerts and symptoms, other events, other objects, and over time.
4 View the Aected Datastore in Relation to Other Objects on page 16
To view the object for which the alert was generated as it relates to other objects, use the topological
map on the Relationships tab in vRealize Operations Manager to visualize the environment.
5 Construct Metric Charts to Investigate the Cause of the Data Store Alert on page 17
To analyze the capacity metrics related to the generated alert, you create charts in
vRealize Operations Manager that compare dierent metrics. These comparisons help identify when
something changed in your environment and what eect it had on the datastore.
6 Run a Recommendation On a Datastore to Resolve an Alert on page 18
As a network operations engineer, you investigated the alert regarding datastore disk space and
determined that the provided recommendations will resolve the problem, particularly the
recommendation to delete unused snapshots. You use vRealize Operations Manager to delete the
snapshots.

understand the steps that you must take to resolve the issue. If implemented, will the
prioritized recommendations resolve the problem?
Which symptoms were triggered? Which were not triggered? What aect does this
evaluation have on your investigation? In this example, the alert that the datastore is
running out of space is congured so that the criticality is symptom based. If you
received a critical alert, then it is likely that the symptoms are already at a critical level,
having moved up from Warning and Immediate. Look at the sparkline or metric graph
chart for each symptom to determine when the problem escalated on the datastore
object.
If you need more information about the aected objects, continue your investigation. Begin by looking
n
at other triggered symptoms for the data store. See “Evaluate Other Triggered Symptoms for the
Aected Data Store,” on page 14.
Evaluate Other Triggered Symptoms for the Affected Data Store
You determined that you need more information about the data store before you decide the best response.
As a network operations engineer, you examine the Impacted Object Symptoms tab to see the other
triggered symptoms for the data store.
If other symptoms are triggered for the object, not just the symptom included in the alert, you can evaluate
them to determine what aect these symptoms could have on the alert to which you are responding, and
whether the recommendations might resolve the problem.
Prerequisites
Verify that you are addressing the alert for which you received an alert message in your email. See
“Respond to an Alert in Your Email,” on page 13.
Procedure
1 In the left pane of vRealize Operations Manager, click the Alerts icon.
2 In any of the alert lists, click the alert name.
The center pane view changes to display the alert detail tabs.
3 Click the Impacted Object Symptoms tab and review the active symptoms.
Option Evaluation Process
Criticality Are other symptoms of similar criticality present that are aecting the object?
Symptom Are any of the triggered symptoms related to the symptoms that triggered the current alert?
Symptoms related to time remaining, capacity, or stress that could indicate storage problems?
14 VMware, Inc.
Chapter 1 Monitoring Objects in Your Managed Environment by Using vRealize Operations Manager
Option Evaluation Process
Created On Do the date and time stamps for the symptoms indicate that they were triggered before the alert you
are investigating, indicating that it might be a related symptom? Were the symptoms triggered after
the alert was generated, indicating that the alert symptoms contributed to these other symptoms?
Information Can you identify a correlation between the alert symptoms and the other symptoms based on the
triggering metric values?
What to do next
If your review of the symptoms and the provided information clearly indicates that the
n
recommendations will solve the problem, implement one or more of the recommendations. For an
example, of implementing one of the recommendations, see “Run a Recommendation On a Datastore to
Resolve an Alert,” on page 18.
If your review of the symptoms did not convince you that the recommendations will resolve the
n
problem or provide you with enough information to identify the root cause, continue your investigation
using the Timeline tab. See “Compare Alerts and Events Over Time in Response to a Datastore Alert,”
on page 15.
Compare Alerts and Events Over Time in Response to a Datastore Alert
To evaluate an alert over time, compare the current alert and symptoms for the datastore to other alerts and
symptoms, other events, other objects, and over time.
As a network operations engineer, you use the Timeline tab to compare this alert to other alerts and events
in your environment so that you can determine if you can resolve the problem of the datastore running out
of disk space by applying one or more alert recommendations.
Prerequisites
Verify that you are addressing the alert for which you received an alert message in your email. See
“Respond to an Alert in Your Email,” on page 13.
Procedure
1 In the left pane of vRealize Operations Manager, click the Alerts icon.
2 Click the alert name link.
The center pane view changes to display the alert detail tabs.
3 Click the Timeline tab.
The Timeline tab displays the generated alert and the triggered symptoms for the aected object in a
scrollable timeline format, starting when the alert was generated.
4 To determine if other alerts are generated for the object, click the other alert buons.
In this example, the datastore alert generated a Risk alert, so the other alerts to add to the timeline are
Health and Eciency. Scroll through the timeline using the week timeline at the boom.
5 To view events that might contribute to the alert, click Select Event Type and click the check box for
each event type.
Events related to the object are added to the timeline. You add the events to your evaluation of the
current state of the object and whether the recommendations can resolve the problem.
6 Click Show Ancestor Events and select Host.
Because the alert is related to disk space, adding the host to the timeline allows you to see what alerts
and symptoms are generated for the host. As you scroll through the timeline, when did some of the
related alerts begin? When are they no longer on the timeline? What was the eect on the state of the
datastore object?
VMware, Inc. 15
vRealize Operations Manager User Guide
7 Click Show Peer Events.
If other datastores have alerts related to the alert you are currently investigating, seeing when the alerts
for the other datastores were generated can help you determine what resource problems you are
experiencing in your environment.
8 To remove canceled alerts from your timeline, click Select Status and deselect the Canceled check box.
Removing the canceled alerts and symptoms from the timeline clears the view and allows you to focus
on current alerts.
What to do next
If your evaluation of alert in the timeline provided enough information to indicate that one or more of

7 Use the options to evaluate the datastore.
For example, what does the map tell you about the number of virtual machines that are associated with
the datastore? If many virtual machines are associated with a datastore, moving them might free
datastore disk space.
What to do next
If your review of the map provided enough information to indicate that one or more of the
n
recommendations to resolve the alert are valid, implement the recommendations. See “Run a
Recommendation On a Datastore to Resolve an Alert,” on page 18.
If you need more information about the aected object, continue your investigation. See “Construct
n
Metric Charts to Investigate the Cause of the Data Store Alert,” on page 17.
Construct Metric Charts to Investigate the Cause of the Data Store Alert
To analyze the capacity metrics related to the generated alert, you create charts in
vRealize Operations Manager that compare dierent metrics. These comparisons help identify when
something changed in your environment and what eect it had on the datastore.
As a network operations engineer, you create custom charts so that you can further investigate the problem,
and to determine if implementing the alert recommendations will resolve the problem that the alert
identies.

c Compare the charts.
For example, if the Capacity | Used Space (%) chart shows an increase in used space, but the Disk
Space | Capacity (GB) did not increase and the Summary | Number of Capacity Consumers did
not decrease, then adding capacity is a solution, but it does not address the root cause.
VMware, Inc. 17
vRealize Operations Manager User Guide
5 To analyze the second recommendation, vMotion some Virtual Machines to a different Datastore,
add related charts to the workspace.
a Enter vm in the metric list search text box.
b Double-click the Summary | Total Number of VMs metric to add it to the workspace
c Compare the 4 charts.
For example, if the Summary | Total Number of VMs chart shows that the number of virtual
machines did not increase enough to negatively aect the data store, then moving some of the
virtual machines is a solution, but it does not address the root cause.
6 To analyze the third recommendation, Delete unused snapshots of virtual machines, add related charts
to the workspace.
a Enter snapshot in the metric list search text box.
b Double-click the following metrics to add the charts to the workspace:
Disk Space | Snapshot Space (GB)
n
Disk Space Reclaimable | Snapshot Space | Waste Value (GB)
n
c Compare the charts.
For example, if the amount of Disk Space | Snapshot Space (GB) increased and the Disk Space
Reclaimable | Snapshot Space | Waste Value (GB) indicates an area where space can be reclaimed,
then deleting unused snapshots will positively aect the data store disk space problem and resolve
the alert.
7 If this is a problematic data store that you must continue to monitor, you can create a dashboard.
a Click the Generate Dashboard buon on the workspace toolbar.
b Enter a name for the dashboard and click OK.
In this example, use a name like Datastore disk space.
The dashboard is added to your available dashboards.
You compared metric charts to determine if the recommendations are valid and which recommendation to
implement rst. In this example, the Delete unused snapshots of Virtual Machines recommendation appears
to be the most likely way to resolve the alert.
What to do next
Implement the alert recommendations. See “Run a Recommendation On a Datastore to Resolve an Alert,”
on page 18.
Run a Recommendation On a Datastore to Resolve an Alert
As a network operations engineer, you investigated the alert regarding datastore disk space and determined
that the provided recommendations will resolve the problem, particularly the recommendation to delete
unused snapshots. You use vRealize Operations Manager to delete the snapshots.
If you have not enabled actions in the vCenter adapter, you can manually delete the snapshots on your
vCenter Server instance.
Prerequisites

This is the delete task. The status should be Completed.
In this example, you ran an action on the datastore in vCenter Server. The other recommendations might
also be valid.
What to do next
Verify that the recommendations resolve the alert. Allow a few collection cycles to run after you run the
n
action and verify that the alert is canceled. Alerts are canceled when the conditions that generated them
are no longer true.
Implement the other recommendations. The other recommendations for this alert require you to use
n
other applications. You cannot implement the recommendations from vRealize Operations Manager.
Use other options to investigate the root cause. See “User Scenario: Investigate the Root Cause of a
n
Problem by Using the Troubleshooting Tab Options,” on page 56 for an alternative example for
investigating the root cause of a problem.
User Scenario: You See Problems as You Monitor the State of Your Objects
As you investigate your objects in the context of this scenario, vRealize Operations Manager provides details
to help you resolve the problems. You analyze the state of your environment, examine current problems,
investigate solutions, and take action to resolve the problems.
As a virtual infrastructure administrator, you regularly browse through vRealize Operations Manager at
various levels so that you know the general state of the objects in your managed environment. Although no
one has called or complained, and you do not see any new alerts, you are starting to see that your cluster is
running out of capacity.
VMware, Inc. 19
vRealize Operations Manager User Guide
This scenario refers to objects that are associated with the VMware vSphere Solution, which connects
vRealize Operations Manager to one or more vCenter Server instances. The objects in your environment
include multiple vCenter Server instances, data centers, clusters (cluster compute resources), host systems,
resource pools, and virtual machines.
As you perform the steps in this scenario, and progress through the stages of troubleshooting, you learn
how to use vRealize Operations Manager to help you resolve problems. You will analyze the state of the
objects in your environment, examine current problems, investigate solutions, and take action to resolve the
problems.
This scenario shows you how to evaluate the problems that occur on your objects, and take action to resolve
problems.
With the Analysis tab, you view the seings for object resources, click the links provided to further
n
analyze the problem, and examine the policy seings and thresholds.
Using the Troubleshooting tab, you examine the symptoms that triggered on the objects, determine
n
when the problems that triggered those symptoms occurred, identify the events associated with those
problems, and examine the metric values involved.
On the Details tab, you investigate the metric activity as a graph, list, or distribution chart, and view the
n
heat maps to examine the criticality levels of your objects.
With the Environment tab, you evaluate the health, risk, and eciency of various objects as they relate
n
to your overall object hierarchy. You view the object relationships to determine how an object that is in a
critical state might be aecting other objects.
To support future troubleshooting and ongoing maintenance, you can create a new alert denition, and
create a dashboard and one or more views and reports. To plan for growth and account for newly approved
projects, you can create and commit capacity projects. To enforce the rules used to monitor your objects, you
can create and customize operational policies.
Prerequisites
Verify that you are monitoring one or more vCenter Server instances. See the vRealize Operations Manager
Customization and Administration Guide.

24 VMware, Inc.
Chapter 1 Monitoring Objects in Your Managed Environment by Using vRealize Operations Manager
You have analyzed the symptoms, timeline, events, and metrics related to the problems on your cluster, and
determined that the heavy workload on the cluster has decreased the cluster density in the last several days,
which indicates that the cluster is starting to run out of capacity.
What to do next
Examine the Details views and heatmaps to interpret the properties, metrics, and alerts to look for trends
and spikes that occur in the resources for your objects, the distributions of resources across your objects, and
data maps to examine the use of various resource types across your objects. See “Examine the Environment
Details,” on page 25.
Examine the Environment Details
Examine the status of your objects in the views and heatmaps so that you can identify the trends and spikes
that are occurring with the resources on your cluster and objects. To determine whether any deviations have
occurred, you can display overall summaries for an object, such as for the cluster disk space usage
breakdown.
To examine the problems with your USA-Cluster further, use the Details views to display the metrics and
collected capacity data for your cluster. Each view includes specic metrics data collected from your objects.
For example, trend views use data collected from objects over time to generate trends and forecasts for
resources such as memory, CPU, disk space, and so on.
Use the heatmaps to examine the capacity levels on the cluster, host systems, and virtual machines. The
block sizes and colors are based on the metrics selected in the heatmap conguration. For example, the
heatmap that shows the most abnormal workload for virtual machines is sized by the Badge|Workload (%)
metric, and is colored by the Badge|Anomaly metric.
Prerequisites
Use the Troubleshooting tabs to look for root causes. See “Troubleshoot Problems with a Host System,” on
page 23
Procedure
1 Click Environment > vSphere Hosts and Clusters > USA-Cluster.

the object.
e Click Show Sparkline to display the activity trend on the virtual machine.
f Click each of the Details links to display more information.
To verify that freeing up memory on the virtual machines has improved the workload of the host system
and the cluster, you can now examine the status of the host system and cluster.
You used views and heatmaps to evaluate the status of your objects and identify trends and spikes, and free
up capacity for your host system and USA-Cluster. To further narrow in on problems, you can examine the
other views and heatmaps. You can also create your own views and heatmaps.
What to do next
Examine the badge status for the objects in your environment hierarchy to determine which objects are in a
critical state, and examine the object relationships to determine whether a problem on one object is aecting
one or more other objects. See “Examine the Environment Relationships,” on page 26.
Examine the Environment Relationships
You use the Environment Overview and List to examine the status of the badges as they relate to the objects
in your environment hierarchy, and determine which objects are in a critical state for a particular badge. To
view the relationships between your objects to determine whether an ancestor object that has a critical
problem might be causing problems with the descendants of the object, you use the Environment Map.
As you click each of the badges in the Environment Overview, you see that several objects are experiencing
critical problems with health, workload, and faults. Others are reporting critical risk status, and many are in
critical time remaining and capacity remaining states.
