Resolution

To resolve the issue, the local admin user must own and be granted the write permissions on the /var/lib/loginsight-agent/liagent.ini file.

1. Log into the affected vRealize Operations Manager node as root via SSH or Console.
2. Run the following command to change the owner and set permissions on the liagent.ini file:

chown admin:admin /var/lib/loginsight-agent/liagent.ini && chmod 644 /var/lib/loginsight-agent/liagent.ini

3. Repeat steps 1-2 on all other affected vRealize Operations Manager nodes.

The vRealize Log Insight agent will now accept changes made from the vRealize Operations Manager UI from Administration > Support > Logs, or Administration > Management > Log Forwarding pages.
