Data collector were showing correct status on CA Performance Center however after a restart of the Data aggregator the Data collector status is System health is failed.

Performance Center is polling the wrong Data aggregator to get the status of the Data collectors.
Following are the steps to check if Performance center is trying to poll the old Data Aggregator for Data collector status.
a) Login to following URL to enable debug on PC Side
Change the Debug levels to Trace for the following
On the PCService.log you should see
ERROR | Status Poller-thread-1 | 2018-05-11 12:06:47,032 | com.ca.im.portal.services.status.impl.Utils
| Failed in sending REST: http://oldDA:8581/rest/dcms
If we are seeing the above. Please restart the CA Performance Center Services
/opt/CA/PerformanceCenter/sso/bin/caperfcenter_sso stop &&
/opt/CA/PerformanceCenter/DM/bin/caperfcenter_devicemanager stop &&
/opt/CA/PerformanceCenter/EM/bin/caperfcenter_eventmanager stop &&
/opt/CA/PerformanceCenter/PC/bin/caperfcenter_console stop &&
/etc/init.d/mysql stop &&
/etc/init.d/mysql start &&
/opt/CA/PerformanceCenter/sso/bin/caperfcenter_sso start &&
/opt/CA/PerformanceCenter/DM/bin/caperfcenter_devicemanager start &&
/opt/CA/PerformanceCenter/EM/bin/caperfcenter_eventmanager start &&
After the Restart the System health should now show the correct status for Data collector.
