From few days we are facing issue with agent connections. Connection state --> Connected (Issue: Instrumentation is not available.)
2019-01-11 07:38:46  severe [native] Exception while connecting to Server/Collector 172.xx.xx.xx, info:<connect()/apr_socket_connect(), 70007, Connection timed out>
2019-01-11 07:38:46  warning [native] Unable to register with Server/Collector 172.xx.xx.xx, CONTINUING WITHOUT INSTRUMENTATION.
To reconnect agent we have to restart JVM multiple time. Which is heavenly impacting business.
Need permanent solution for this. Kindly suggest for solutions.
Hello @Ramesh N.
If there is no firewall in between agent and collector (not recommended) and even though you are facing the same situation then use the DT_WAIT (e.g. wait=30) with the environment variable to increase the connection establishment time.
This is the registry key 'wait'. It is the maximum time in seconds (default: 20; was 60 until 5.5) an Agent waits for a connection to an AppMon Collector. If the connection cannot be established within this time-frame, the application continues uninstrumented.
