Command to restart java agent or JVM on linux?



Two of our java agents are having instrumentation issues. I see connection timed out info in logs.

Can I restart manually java agent or JVM from that linux box?

The java agents aren't separate processes, they are modifications to the code of the application/jvm so they run with the application. This means that the only way to restart the agent is to restart the application. This is the only option to restore instrumentation if the agents could not reach the collector at startup.


So the only solution for this is to restart the application right?

When they say instrumentation not available these agents do they still report any data or they skip data?

If you see the message "instrumentation not available" then you will not receive any transactional data from that JVM. A JVM restart is your only option.

Thanks Joseph. In this case we will request to restart application and hopefully it should fix the issue.

It might be a good idea to inspect the agent logs to determine the exact reason that it was not able to instrument the JVM last startup. Perhaps your collector is not located in an appropriate location for this agent? Let us know what messages exist in the log.
