Environment

VMware Smart Assurance - Watch4Net/M&R

Cause

The above issue has been found to occur in environments where the icStats.sh/icStats.cmd and ICSTATS.import did not have the required "execute" permissions on the Smarts server.

Resolution

If you encounter this issue, do the following:

1. Ensure the correct execute permissions are set on icStats.sh and ICSTATS.import.
2. Restart the Smarts domain manager.
3. After a few polling cycles, confirm that the Smarts health data is present in the Watch4net Front End/Web Portal reports.

Additional Information

The above issue occurs even though the required scripts provided with Watch4net have been deployed in the Smarts installation, and the instructions in /opt/APG/Collecting/Smarts-Collector/Default/contrib/sm-domain-health/README.txt were followed correctly.
