System health showing failed for multiple components in CAPM

Products

• CA Performance Management - Usage and Administration
• DX NetOps

Issue/Introduction

After rebooting the DX NetOps Performance Management server machines (DX NetOps Portal, DA, DC & DR) all processes are restarted as per:

 

Broadcom TechDocs : DX NetOps 20.2 - Restarting CAPM components

 

Sometimes, everything appears to stop and start as expected, with the data repository up and running and the collectors "appear" to be running ok (service shows running), and the DA "appears" to be ok (service shows running).  However, when logging into DX NetOps Portal, System Status shows the Data Aggregator (DA) with "Unable to Contact" with both it and the Data Collector/s (DC) showing "failed".

Environment

DX NetOps Performance Management 3.6.x and later

Resolution

Checked the DA as the karaf.log was very small.

Check the processes using:

ps -ef | grep -i activemq.jar

If there are 2 activemq processes running, then shut down the dadaemon, activemq and if necessary, kill the still running activemq process. Then restart activemq and the dadaemon as per normal. Then restart the DC's.
