Issue/Introduction

After restart of the MOM, most of the pre-configured dashboards and metrics in management modules are not reporting in WebView or APM workstation. We can see that individual metrics are reporting as normal in the Investigator.

 

 

 



Environment

Release : 10.x

Component : APM

Cause

The IntroscopeEnterpriseManager.log file contained message like the following

[ERROR] [main] [Manager.Bootstrap] Cannot write to Management Module file: /opt/Introscope10.5.1.8/config/modules/domain1/Accounts.jar

 [ERROR] [main] [Manager.Bootstrap] Could not read Management Module file /opt/Introscope10.5.1.8/config/modules/domain1

It was identified that the ownership of the majority of the management module jar files in the domain subfolders was root.

This caused a problem because the file permissions were set to 644 so the user running the Enterprise manager did not have permission to update these files during start up.

Resolution

Changing the ownership of the config/modules hierarchy to the user account running the Enterprise Manager and restarting the MOM resolved the problem.

It is suspected that the EM had been mistakenly previously been started by the root user account.
