Java Event List Configuration
This chapter covers how configure the Cisco Info Center Java Event List. You need only read this section
if you have installed Java support for the Java Event List.
This chapter includes the following sections:
• “Introduction”
• “Configuration Procedure”
• “License File”
• “Creating HTML Pages”
• “Running the JELD Process in Background”
The Java Event List is used to distribute and manage Cisco Info Center events through the World Wide
Web (WWW). The Java Event List uses a background server process, which obtains information from
the Cisco Info Server.
The background process, called jeld, and a Web server should be installed on the same machine to
overcome Java browser security issues.
When a Web browser makes a connection to the Web server, the server can send back an HTML page
containing the Java applet to the browser. The applet then connects to the jeld and requests a
configuration. The jeld

The configuration information is stored in an Cisco Info Server database table and is configured using
the JEL Advanced Configuration Editor (JACE).

Configuration Procedure
The Java support components are, by default, installed in the $OMNIHOME/java directory. The
configuration procedure for Java support covers the following steps:
1. Install a Web server and set up the communications to Cisco Info Center.
2. Copy the class files to the publication home directory of the Web server.
3. Set the jeld properties files.
4. Create configurations with JACE.
5. Create the HTML pages.
6. Run the background process, jeld.
These steps are described in detail in the following sections.
Web Servers
In order to use the Java Event List, you must have a Web server installed and configured to support Java
applets. The Web server must be installed on the same machine as the Java support components. You can
obtain free Web servers from the WWW.

6-2
For information about how to configure the Web server to support Java applets, for example,
initialization of class files, see your Web server documentation.
You should configure the system that runs the Web server to connect to Cisco Info Center. To do this,
you install a Cisco Info Admin Desktop on the machine that runs the Web server to check the
connectivity requirements. See the Cisco Info Center Installation and Configuration guide for more
information.
You also need to generate an interfaces file. This file contains information about which machines run
the Cisco Info Servers and also the communications between those machines. See the Cisco Info Center
Installation and Configuration guide for more information.

Chapter 6 Java Event List Configuration
Publishing Class and Zip Files
Before you can create HTML pages for the WWW, you must publish the class and zip files on the Web
server. The class files are in the $OMNIHOME/java/jel directory. This directory contains the following
subdirectories:
• classes containing the Java class files
• html containing an example configuration of the applet.
Copy these directories to the publication home directory of your Web server. To test the applets, load the
pages from the Web server.
For example, specify your server name with the following URL:
http://<your-server-name>/html/index.html
Setting the Properties File
The jeld.props properties file is located in the $OMNIHOME/java/props directory. You must modify
this file to match your system configuration. An example properties file is shown below.
jeld.Cisco Info Server.host: omnihost
jeld.Cisco Info Server.port: 4100
jeld.Cisco Info Server.user: root
jeld.objectserver.password
jeld.objectserver.1.host: host

Configuration Procedure
78-5664-05
The following sections explain the items in the properties file and how to set the values.
Cisco Info Center Administrator Reference
6-3
Configuration Procedure
Info Server Connection Properties
The properties file provides three methods of connecting to an Info Server. These are:
1. Connection to a list of Info Servers. JELD tries each Info Server in the list until a connection is
made. This is the preferred method.
2. Single connection to an Info Server. This method is provided for backward compatibility with
previous versions.
3. Connection to a list of URLs. Each URL specifies fully an Info Server connection. JELD tries each
URL in the list until it connects to an Info Server. This option is only for use by experienced
integrators. It should not be used in normal implementations.
Connection to List of Info Servers
The preferred method for the JELD to connect to an Info Server is for it to try to connect to each Info
Server in a list until it makes a connection. This means that you can specify a fallback Info Server, or
have the JELD retry the same one several times.
Chapter 6 Java Event List Configuration
Host Name
Port
Each Info Server is specified in the properties file by a set of properties. Each property includes a number
which identifies the position of the Info Server in the list. The property names for the first Info Server
are:
jeld.objectserver.1.host:
jeld.objectserver.1.port:
jeld.objectserver.1.user:
jeld.objectserver.1.password:
The second Info Server has 2 instead of 1, and so on for subsequent Info Servers.
You can override the entries in the properties file from the command line. For more information, see the
“JELD Command Line Utility” section on page B-2
This entry contains the host name where the Cisco Info Server is located. For example, specify:
jeld.objectserver.host: <omnihost>
Where <omnihost> is the name of the host.
You can override this entry with the jeld command line option -host.
This entry contains the port setting for the Cisco Info Server. For example, specify:
jeld.objectserver.port: 4100
You can override this entry with the jeld command line option -port.
User Name
6-4
This entry contains a user name (the suggested user name is jeld) for the Cisco Info Server. For example,
specify:
jeld.objectserver.user: jeld
Cisco Info Center Administrator Reference
78-5664-05
Chapter 6 Java Event List Configuration
Password
This entry contains the jeld password for the Cisco Info Server. The password should be encrypted using
the nco_crypt command. For example, specify:
jeld.Cisco Info Server.password: <string>
Where <string> is the encrypted password. To create an encrypted password, specify:
nco_crypt <password>
Where <password> is the unencrypted form of the password. The nco_crypt command displays an
encrypted version of the password.
Single Connection to an Info Server
This option is provided for backward compatibility only. These lines are commented out in the example
configuration file.
Use the following fields to specify a connection to a single Info Server.
jeld.objectserver.host:
jeld.objectserver.port:
jeld.objectserver.user:
jeld.objectserver.password:
Configuration Procedure
Enter the Info Server details against these properties. The JELD tries to connect to the specified Info
Server. If it cannot connect the first time, it tries a second time. If it cannot connect then, it returns a
failure.
Info Server URL List
Note Only experienced integrators should use this connection method.
When you specify an Info Server URL list, the data from each URL is used to establish a connection to
the Info Server. You can use this option you need to specify fully the connection to an Info Server. The
property name is:
jeld.objectserver.1.url
In this property name, url is the address of the machine running the Info Server. It is not a web reference
and does not include the
This property is commented out in the example configuration file. Replace the number 1 with the number
2 for the second Info Server, 3 for the third Info Server and so on.
JDBC Driver Properties
http: prefix.
78-5664-05
This option defines the way in which the connection to the Info Server is established:
jeld.jdbc: com.sybase.jdbc.SybDriver
It should not be changed or removed except under instruction from technical support.
Cisco Info Center Administrator Reference

Configuration Procedure
JELD Server Properties
There are two JELD server properties: listenport and maxconns.
Listen Port
This entry contains the listen port number. For example, specify:
jeld.listenport: 7575
You can override this entry with the jeld command line option -listenport.
Maximum Connections
This entry contains the maximum number of connections supported by the nco_jeld process. For
example, specify:
jeld.maxconns: 3
You can control the number of connections a single jeld process can handle, however, this does not
override the number of available licences.
Chapter 6 Java Event List Configuration
JELD Global Security Properties
There are two JELD global security properties: ips and hosts.
IPS
This entry is a list of the domains allowed to connect to the applet. For example, to allow only 10.0.0.1,
10.0.0.5, and 10.0.0.10 to connect to the applet, specify:
ips:+10.0.0.1 +10.0.0.5 +10.0.0.10 -*
To allow only machines in the domain 10.n.n.n to connect, specify:
ips:+10.* -*
To allow any domain to connect, specify:
ips: +*
Hosts
This entry is a list of hosts allowed to connect to the applet. For example, to allow only machine1,
machine2, and machine3 to connect to the applet, specify:
hosts:+machine1 +machine2 +machine3 -*
To allow only machine1 to connect, specify:
hosts:+*machine1 -*
To allow any machine to connect, specify:
hosts:+*

Chapter 6 Java Event List Configuration
Log File Properties
There are two log file properties: logdir and logfile.
Log Directory
This entry contains the name of the directory in which the log file is located. For example, to ensure the
log file is located in the /opt/Omnibus directory, specify:
jeld.logdir: /opt/Omnibus
Log File
This entry contain the name of a log file. The log file contains diagnostic information about the
background process, jeld. For example, to use a log file called jeld.log
jeld.logfile: jeld.log
License File
Configuration Procedure
,specify:
The JELD license file is $OMNIHOME/java/props/jeld.lic.
The license file contains information about the IP address of the host on which the JELD is licensed to
run, the license key, the number of licenses, and the expiry date of the JELD license. For example, a
license file could look like the following:
jeld.license.key:string
jeld.license.address:IP_address
jeld.license.count: 3
jeld.license.expire:01/Feb/2000
To obtain a license file, email Micromuse Technical Support (support@micromuse.com). After they
send you the information for a license, use the text editor of your choice to create a jeld.lic file and paste
the information that they send you into the file. Then save the file in the
directory.
Info Server Connection and Reconnection
This section describes how JELD makes a connection when it is configured to connect to a list of Info
Servers, and how it reconnects if necessary. For more information about the Info Server connection see
the “Info Server Connection Properties” section on page 6-4.
Initial Info Server Connection
When JELD is started, it tries to establish a connection to the first Info Server in the properties file. If it
cannot, it tries to establish a connection to the second Info Server.
If you wish to try to connect to the same Info Server twice, enter the same details in the first and second
Info Server properties.
opt/Omnibus/java/props
78-5664-05
Cisco Info Center Administrator Reference
6-7
Configuration with the JACE Editor
There is no limit to the number of Info Servers that you can specify in the properties file or the number
of times you can enter the details of the same Info Server.
Once a connection has been established, the JELD can respond to requests from the Java applet in the
JEL.
Info Server Connection Failure
If the connection to the Info Server is broken, the JELD shuts down automatically. The JEL detects the
shutdown of the JELD, report an error on the desktop and offers the user the option of reconnecting.
If the JELD is running under process control it can be restarted automatically. As a new process the JELD
tries to establish a connection with an Info Server as described in the “Initial Info Server Connection”
section on page 6-7.
A dialog box appears on the JEL to reconnect to the JELD. If the JELD has established a new Info Server
connection, the JEL resynchronizes the data from the Info Server.
Fail Over Support
Chapter 6 Java Event List Configuration
When you enter a list of Info Servers in the jeld.props file, the JELD attempts to connect to each Info
Server in turn until a successful connection is made.
For the JELD to continue to operate after a failure, every Info Server listed in the
contain the same JELD configuration table, and the JELD must be restarted automatically under process
control.
Configuration with the JACE Editor
For Java configuration, use the JEL Advanced Configuration Editor (JACE). JACE is a table-orientated
editor that allows you to manage configurations. These configurations are stored in the jel.jel_props
Cisco Info Server table, to which the jeld is connected. You must have super user privilege to use JACE.
For maximum flexibility, the configuration files include options to take particular settings from the
HTML parameters. These parameters include, view name, fields, order, and filter.
Starting JACE
Before starting JACE, set OMNIHOME:
host# setenv OMNIHOME=/opt/Omnibus
To start JACE, specify the following command:
host# $OMNIHOME/java/bin/jace

Sets and properties can be added to the current configuration. The value of a property in the current
configuration overrides the same property in the included configuration.
If a configuration includes another configuration that contains the admin set, the included configuration
can point to the including configuration. This creates an loop that never ends. JACE cannot validate the
included configuration when this occurs. It should be avoided.
For the JELD to continue to operate after a failover, every Info Server listed in the jeld.props file must
contain the same JELD configuration table. You must copy any changes that you make to the JELD
configuration table in JACE to all of the Info Servers in the
jeld.props file.
For more information on this topic, see the “Connection to List of Info Servers” section on page 6-4.

Chapter 6 Java Event List Configuration
Creating HTML Pages
To configure the JEL, you add applet pa rameters t o t h e HTML pag e s . An example HT M L fi l e i s provided
in the following file:
$OMNIHOME/java/html/jel1.htm.
The following sections describe the available parameters and how to set their values.
The APPLET Tag
The applet tag defines where the code for the JEL is located and the class that should be run. It also
defines the width and height of the applet in the HTML page. For example:
<APPLET CODEBASE=”../classes” archive=”jel.zip”
CODE=”COM.micromuse.jel.Jel.class” WIDTH=200 HEIGHT=64>
For Netscape Communicator and other Java 1.1 compliant browser users, change the archive entry to
jel.jar. For example:
<APPLET CODEBASE=”../classes” archive=”jel.jar”
CODE=”COM.micromuse.jel.Jel.class” WIDTH=200 HEIGHT=64>
Creating HTML Pages
There must be a corresponding </APPLET> tag at the end of the applet.
Host Parameter
The host parameter allows you to specify a host to which the applet connects directly. The applet can
connect only if the host has no access control. Use this tag with caution. For example:
<param name=”host” value=”host”>
Configuration Parameter
The config parameter allows you to specify the configuration to use. The configuration is defined with
JACE, as described in the “Configuration with the JACE Editor” section on page 6-8. For example
<param name=”config” value=”jel1”>
Port Parameter
The port parameter allows you to specify the port number. For example, enter:
<param name=”port” value=”7575”>
78-5664-05
This parameter defaults to 7575.
Cisco Info Center Administrator Reference
6-21
Creating HTML Pages
ViewName Parameter
The ViewName parameter is a string that labels the button and window that appear in float mode. For
example:
<param name=”ViewName” value=”High Severity”>
This parameter is used when the configuration namefromhtml is set to true.
Order Parameter
The Order parameter is the SQL text of an ordered by clause. For example:
• Severity desc orders by descending severity
• Severity asc orders by ascending severity
You can specify multiple orders, with precedence going from left to right, by separating entries with a
comma. For example, enter:
<param name=”Order” value=”Severity desc, Serial asc”>
Chapter 6 Java Event List Configuration
This parameter is used when the configuration orderfromhtml is set to true.
ViewFields Parameter
The ViewFields parameter controls the display of fields. For example, enter:
<param name=”ViewFields” value=”Serial,,Serial,R,10|Node,,Node,,16|
Summary,,Summary,,64|Severity,,Sev,,10|Acknowledged,,Ack,,3|FirstOccurence,,First,,16|Owne
rID,,Owner,,16”>
The fields are listed in the following format:
FieldName,Justify,Title,JustifyTitle,Width [| FieldName,Justify,Title, JustifyTitle,Width
]...
The fields are as follows:
• FieldName is the field from the Info Server
• Justify is the justification of the field name. If omitted the default is left.
• Title is the text to appear above the column when it is displayed,
• JustifyTitle is the justification of the column title. If omitted the default is left.
• Width is the number of characters.
The vertical bar character (|) is used to separate the entries.
If you do not include the
Acknowledged field, no acknowledgment shading appears. This feature allows you to prevent severity
and acknowledgment information appearing in the event list. This parameter is used when the
configuration
Severity field, no severity coloring appears. If you do not include the

Chapter 6 Java Event List Configuration
Filter Parameter
The Filter parameter allows you to define the filter. This is the value of an SQL where clause and can
contain any valid filter text. For example, enter:
<param name=”Filter” value=”Severity>3”>
This parameter is used when the configuration filterfromhtml is set to true.
Tools Parameter
The Tools parameter defines tools that call CGI scripts (or other web-based tools) according to the value
of fields in selected alerts. The parameter’s value consists of a list of tool definitions:
<param name=”Tools” value=”
Tool1(type)(BaseURL)([CGIParam,Value,CGIParam,Value...)
Tool2(type)(BaseURL)([CGIParam,Value,CGIParam,Value...)
.
.
”>
Configuring Tools
Each tool is defined on a single line in the following format:
NameforMenu(type)(BaseURL)(CGIParam,Value,CGIParam,Value...)
For example:
Ping multiple hosts (all)(http://armagnac/cgi-bin/ncping)(Node,Node,Serial,Serial)
This parameter is used when the configuration toolsfromhtml is set to true.
See the “Configuring Tools” section on page 6-23 for details of the parameters.
Configuring Tools
You can specify tools for use with alerts displayed in a Java event list. Each tool consists of a URL that
points to a web based application, for example a CGI script or page relevant to the alert. You can
configure tools either in the JACE, as part of the JEL configuration, or in the HTML for a Java event list
web page. If you define tools in the web page, the JEL configuration must have the
to true for a Java event list to use them.
Each tool consists of the following:
• A name
• A base URL
• A type
• Parameters derived from the alert
toolsfromhtml set
Tool Name
78-5664-05
The name of the tool is displayed in the Too ls menu title bar. In a tool defined in JACE, it is defined in

Configuring Tools
Base URL
Chapter 6 Java Event List Configuration
You must specify a base URL that forms the stem of the URL for each tool. The rest of the tool’s URL
is derived from the parameters in a way that depends on the tool’s type. See the “Tool Type” section on
page 6-24 and the “Tools Parameters” section on page 6-24 for details.
In a tool defined in JACE, the base URL is defined in the second (

Tools of type go have no parameters. In a tool defined in JACE, the params property should be empty. In
a tool defined in an applet, the fourth parameter should be null:
Show Home Page(go)(http://armagnac/)()
Tools of type one have one or more parameters, each of which that consists of the name of a parameter
used by the tool, and its value. The list of parameters is itself a single parameter in the tool definition:
Ping a single host(one)(http://armagnac/cgi-bin/ncping)(Node,Node,Serial,Serial)
The contents of the final parentheses in these examples are the same as the value of the params parameter
in a tool defined in JACE.
The name/value pair is passed to the script at the URL. The value of each named parameter is taken from
the specified field in the alert. In this example, the script expects a
value of the
the script as the value of a
Node field in the first alert. The value of the Serial field in each alert is similarly passed to
Serial parameter. The name of the parameter does not have to be the same as
Node parameter, and runs with the
the name of the field from which it takes its value, although this helps in tracking values.
78-5664-05
Chapter 6 Java Event List Configuration
Tools of Type All
Tools of type all have one or more parameters, defined in the same way as for tools of type one:
Ping multiple hosts(all)(http://armagnac/cgi-bin/ncping)(Node,Node,Serial,Serial)
In this example, the script expects a Node parameter, and runs with the value of the Node field in the each
selected alert. The value of the
a
Serial parameter.
Tools of Type Curl
A tool of type curl accesses a URL constructed from the values of the third and forth parameters. The
third parameter is a base URL, for example,
values which can be either taken from fields in the alert or passed as strings, included in quotes.
For example, if you have a directory structure that contains appropriate HTML pages for each type of
alert, the following file could contain instructions for dealing with a critical (severity 5) alert involving
a disk failure on the node
http://armagnac/info/demo5/Disk/help.html
Running the JELD Process in Background
Serial field in each alert is similarly passed to the script as the value of
http://armagnac/info. The fourth parameter is a list of
demo:
To access this URL when the relevant alert occurs, the tool definition is:
Help(curl)(http://armagnac/info/) (Node,Severity,”/help.html”)
Running the JELD Process in Background
To run t h e jeld process in background, enter the following:
$OMNIHOME/java/bin/jeld&
The JELD process can also be run under process control. For information on process control, see
Chapter 2, “Process Control.”
You can then open the HTML page in a web browser. The page displays the configuration settings.
Figure 6-6 shows the web browser with a configuration modified to show the metric and a histogram in
the monitor box.
