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:

1. Stop DC:   /etc/init.d/dcmd stop
2. Stop DA:   /etc/init.d/dadaemon stop
3. Stop ActiveMQ from DA:   /etc/init.d/activemq stop
