Cockpit Plugin

In order to be able to control the process of correlation via inbox storage, we created a cockpit plugin showing the messages in the system. In order to activate it, just add the following dependency to your classpath:

<dependendcy>
  <groupId>io.holunda</groupId>
  <artifactId>camunda-bpm-correlate-cockpit-plugin</artifactId>
</dependendcy>

After restart of the Camunda 7 engine, navigate to the Cockpit WebApp and you will see an additional tab Correlation, showing the message overview.

The table above represents messages stored in the inbox table waiting for the correlation. The columns from left to right are:

• Message State
• Message id
• Payload type
• Time of ingestion via Ingress
• Number of retries left
• Time of next retry attempt
• Available actions (if available):
  • Show Stacktrace
  • Change retry parameters (next retry, number of retries)
  • Pause / Resume delivery
  • Delete message

If the error is present, you will be able to see the stacktrace in causing the error during correlation:

To change message correlation parameters, click on the corresponding button:

The following message states are available:

• :glyphicon-ok-sign: green: ok
• :glyphicon-remove-sign: red: max retries reached
• :glyphicon-hourglass: orange: paused
• :glyphicon-circle-arrow-right: blue: retrying
