Today we announce the release of camunda BPM 7.0.0-alpha6. In this release we focused on visualizing process instance state on top of a rendered diagram in cockpit. We added the following features:
- Process Instance Detail view in cockpit visualizing active activity instances with count
- Updated process definition view to include failed jobs from sub process instances
- Added persistent Activity Instance tree in process engine
- Event Subscription Query is exposed in REST and Java API
41 issues were closed. See the complete release notes in Jira.
Process Instance Detail View in Cockpit
In cockpit we started work on the process instance detail view. This view will allow you to drill down into a single process instance and explore it’s running and completed activities as well as the variables, tasks, jobs… associated. To open the process instance detail view, you can select a process definition on the start page (dashboard), navigate the the process definition page and select a process instance from the instance list.
How does it work?
In order to visualize these diagrams, Camunda Cockpit creates two client side models:
Both the process definition tree and the process instance tree have the same structure (ie. activity instances in the process instance tree are at the same level as their corresponding activity definitions in the object model.). In order to achieve this, we had to make a couple of additions in the core process engine (PVM-Process Virtual Machine).
Visualizing the Activity Instance Tree
We will visualize the Activity Instance tree in the process instance detail view on the left hand side:
