Issue/Introduction

Java agent is install by UMA agent. There are more then 100 Application PODs that has been enabled to monitored by java agent. Java agent intermittently show metric gaps and also agent log showing agent is connecting and disconnecting. If few Application PODs are running then this issue is not occurring.

Cause

The connects and disconnects are occurring with Java agent and not with the UMA agent components.

Java agent is part of the Application JVM POD and it does not run as an independent POD with UMA agent components.

Resolution

Lowering the number of application PODs resolved the issue.

Most likely the issue is with resources availability in your cluster on the Application side and not UMA or Java agent side.

Look into the Memory, heap settings, CPU and network side for Application JVM PODs which are monitored by the Java agent.
