After upgrading to 23.3.5 the Dynamic Alarm title is no longer displayed

Products

• Spectrum
• Network Observability
• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

The Alarm Title column displays the same information as the Alarm Type in the OneClick Console.

Note also that this affects the DX UIM <->Spectrum integration results as the Spectrums Alarm Title is more generic and customers may prefer UIM's Alarm message title to be used and displayed in OneClick instead when viewing the landscape.

Environment

• DX NetOps Spectrum OneClick 23.3.5
• DX NetOps Spectrum OneClick 23.3.6

Cause

The default, OOTB configuration was changed in the NetOps Spectrum version 23.3.5 installer.

In the $SPECROOT/tomcat/webapps/spectrum/WEB-INF/web.xml file of the OneClick server:

<context-param xmlns="">
    <param-name>com.aprisma.ClientAlarmUpdate.ParseByteCode</param-name>
    <param-value>true</param-value>
    <description>This parameter defines the parsing of byte code in alarm title.</description>
  </context-param>

Resolution

1. Edit the $SPECROOT/tomcat/webapps/spectrum/WEB-INF/web.xml file of the OneClick server

2. Change the parameter (com.aprisma.ClientAlarmUpdate.ParseByteCode) from true to false

3. Then restart the Spectrum Tomcat service to put the change in place.

• $SPECROOT/tomcat/bin/stopTomcat.sh
• $SPECROOT/tomcat/bin/startTomcat.sh

As of Spectrum 23.3.7 or higher, the default install value will be set to false.

Additional Information

This can also affect out of the box UIM integration with Spectrum using the spectrumgtw probe, as we use Dynamic Alarm titles to enrich the alarms without any user customizations.

When this is not working, you will see generic alarms such as "ALARM ON UIM MANAGED RESOURCE" instead of the UIM alarm title, for example->  "Disk Usage (%) on ...." .
