And thanks to Stefan for your continuous fight for better IE compatibility ;-).

Under the Hood

A major contribution to this release was Daniel’s work a sophisticated authorization mechanism. Through that mechanism you have fine grained control over which users and groups may create, view, edit and delete which resources.

As a first step, we applied that mechanism to cockpit, Tasklist and the admin app. From today on, you will only be able to access the apps you have been authorized for ;-).

Furthermore, superpowered users may configure all this through the extended admin application.

Daniel also worked on improving the history, both in terms of structure and performance. The result moved into our code base, expect a blog post about it, soon.

In the meantime Roman and I overhauled the cockpit process definition and process instance view internals. The result is a small library called angular-data-depend and a cleaner code base.

Each action you perform is reflected in the url. As a result, you are able to walk back through what you have done using your browser’s history.

Last but not least, we created a process instance filter that tells you exactly where you are and what you filter for. It allows you to narrow the displayed process instances based on their business key and process variables, too.

  • Monitoring Camunda Platform 7 with Prometheus

    Monitoring is an essential facet of running applications in a production system. Through this process, organizations collect and analyze data, and determine if a program is performing as expected within set boundaries. When combined with alerting, monitoring allows for detecting unexpected system behavior to mitigate exceptional situations as fast as possible. Furthermore, tracking the performance of a system enables organizations to improve those aspects that have the biggest impact with higher priority. One essential aspect of monitoring is the list of key metrics you want to observe. There are different categories of statistics that can be of interest here. To observe the defined metrics, there are plenty of application monitoring tools on the market today. They differ in many aspects...

  • Securing Camunda 8 self-managed cluster and applications...

    Directory services are an effective way to manage an organization’s users, groups, printers, devices, and more. Most organizations accomplish this using Active Directory, Apache Directory, Oracle Internet Directory, or other similar tools. Recently I worked with a customer who wanted to see how he could secure the Camunda 8 Platform and process applications with such a directory. Their requirements consisted of: Allowing Directory users to access Camunda applications (Tasklist, Operate, Optimize) Accessing secured Tasklist & Operate APIs from our custom project Securing the custom project In this article, I’ll briefly explain the 3 easy steps taken to fulfill their requirements which include: Federate users from the Directory service into Keycloak Declare an application in Identity to access Camunda APIs Configure...
