Introduction:
When the Data Collectors are not connected or display a status of Unknown, this could be a result of a bad upgrade of the DC or it could be other components of Performance Management not working. Here are some troubleshooting steps that could help reconnect your Data Collectors.
Instructions:
Confirm Status of Data Collector/s
/etc/init.d/dcmd status
Stop and Restart your Data Collector/s
/etc/init.d/dcmd stop /etc/init.d/dcmd status (to confirm it has stopped) /etc/init.d/dcmd start
Stop DC, move data and Restart your Data Collector/s:
/etc/init.d/dcmd stop ps -ef | grep java kill -9 <PID> (if Needed) cd /opt/IMDataCollector/apache-karaf-2.3.0/ mv data data.old /etc/init.d/dcmd start
Stop/Restart your Data Collector/s and Aggregator:
Stop DC: /etc/init.d/dcmd stop
Stop DA: /etc/init.d/dadaemon stop
Stop ActiveMQ from DA: /etc/init.d/activemq stop
Start DA: /etc/init.d/dadaemon start
Start DC: /etc/init.d/dcmd start
In Performance Center UI go to Admin/Data Sources and Re-sync the DA (note: re-syncing can take up to 5 min)
