The Camunda BPM is a lightweight, opensource BPM platform (See here: https://camunda.com/bpm/features).
The “Cockpit” application within Camunda is the admin dashboard where deployed processes can viewed at a glance and details of running processes are displayed by the process instance ids. Clicking on a process instance id reveals runtime details while the process is running – process variables, task variables etc. If there is an error thrown from any of the services in a flow, the Cockpit application allows “retrying” the service manually after the coded automatic-retries have completed.
The steps below show how to retry a failed process from the Cockpit administrative console
From the Process Detail Screen select a failed process (click on the GUID link)
Then on the Right Hand side you should see under “Runtime” a “semi-circle with arrow” indicating “recycle” or “retry” – click on this
This launches a pop-up with check-boxes with IDs for the failed service tasks and option to replay them. Notice these are only tasks for “this” instance of the “flow”
After the “Retry” is clicked another pop-up indicates the status of the action (as in “was the engine able to process the retry request”. The actual Services may have failed again)
