Gaining insight into the Performance of camunda Process Engine

The camunda process engine has a very active codebase and is constantly evolving. Only last week we did a major refactoring, re-implementing the way the BPMN Boundary Event, Event Subprocess, Terminate End Event and similar constructs work. In summer we introduced an activity instance model and rewrote the history implementation, turning it into a fire-and-forget event stream.We also constantly add new features such as incidentsand many others. When doing such refactorings, the extensive process engine testsuite gives us the confidence that we do not break existing functionality from a functional perspective (process engine currently has 1669Testases, over 500 were added last year). On top of that, we put quite some effort into database migration testing, making sure that you can…

Get your Tasklist as RSS Feed

I don’t like watching my Tasklist all day. Getting email notifications for tasks that I should complete is nice, but sometimes I don’t want to complete the task right after being notified but still need to keep in mind there is something pending. This is how I came to create a simple PHP script that exposes my tasks as an RSS Feed. I can use that in my personal master dashboard (Microsoft Outlook) to keep track of my camunda Tasklist. Here is the result: Huh wow, how did I do that? I used the camunda BPM PHP SDK plus 40 lines of code. You can find them here: Tasklist RSS Sources

Camunda Modeler as a standalone tool

Monitor collaborating executable BPMN 2.0 processes in cockpit

In a current customer project we faced the issue that there were two executable processes – independent of each other. So far – so normal. But these two processes had to sync status here and there – so they were clearly related, but not by using a Call Activity. BPMN 2.0 allows this by communication via messages as shown in the following example. But how to keep track of this in monitoring? We developed a small cockpit plugin to show the related process instances – see below. The process is in the area of IT infrastructure management, where changes are handled by multiple different change processes handled by different departments which are pretty autonomous. But actually for today’s post it is not…
