New Design for Camunda Tasklist

With this release, Tasklist gets a new look:

All information about this change can be read in a dedicated blogpost.

Accessibility Features for Tasklist Users

The accessibility of Tasklist has been improved as well. All elements and buttons are now accessible using keyboard navigation. There are also keyboard shortcuts which improve productivity of Tasklist users. It is also possible to add additional shortcuts and use them in Tasklist plugins.

New Cockpit Dashboard & Navigation

The Cockpit dashboard is the main entry point for monitoring and operations. Over the past releases, a lot of features were added to Camunda Cockpit. As a consequence, the dashboard became more and more crowded.

With this release we provide a first snapshot of where we want to go with the dashboard. The new dashboard provides an overview over four categories in Cockpit: Processes, Decisions, Deployments and Reporting. In addition, it shows some aggregated counts like the number of deployed processes or running process instances. Note that we have not done any actual styling on this so you can expect it to look a bit “fancier” in the final release 🙂

As you would expect, the new dashboard can still be extended with plugins and custom functionality. See the documentation for a list of all plugin points in Cockpit

Improved Support for Multi Tenancy

With 7.5, Camunda introduces multi tenancy features which allow users to manage multiple tenants (aka isolated workspaces) in the same database over a single API entry point. Compared to the last alpha release, alpha3 enhances support for multi tenancy by making the following APIs and features tenant aware:

  • Message Correlation API
  • Signal API
  • Suspend / Activate API
  • Support for working with shared resources (Example: deploy a process definition for all tenants but assign a tenant’s instances to the tenant’s workspace)
  • Call Activities
  • DMN Decisions and Business Rule Tasks
  • History
  • Tenant Ids in Cockpit and Tasklist

More Powerful Process Instance Migration

With this release it is possible to migrate process instances which have multi-instance activities. In addition, instances can be migrated asynchronously using the new batch API.

This is code example using the (open source) Java API:

ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration().buildProcessEngine();
RepositoryService repositoryService = processEngine.getRepositoryService();
RuntimeService runtimeService = processEngine.getRuntimeService();
TaskService taskService = processEngine.getTaskService();

repositoryService.createDeployment()
  .addModelInstance("process1.bpmn", Bpmn.createExecutableProcess("coffee-process")
    .startEvent()
      .userTask("prepare-coffe")
    .endEvent()
    .done())
  .deploy();

ProcessInstance pi = runtimeService.startProcessInstanceByKey("coffee-process");
Task prepareCoffeeTask = taskService.createTaskQuery().singleResult();

// no wait, if I prepare this coffee, I cannot drink it :(

repositoryService.createDeployment()
  .addModelInstance("process1.bpmn", Bpmn.createExecutableProcess("coffee-process")
    .startEvent()
      .userTask("prepare-coffe")
      .userTask("drink-coffee")
    .endEvent()
    .done())
  .deploy();

ProcessDefinition v1 = repositoryService.createProcessDefinitionQuery().processDefinitionVersion(1).singleResult();
ProcessDefinition v2 = repositoryService.createProcessDefinitionQuery().processDefinitionVersion(2).singleResult();

MigrationPlan migrationPlan = runtimeService.createMigrationPlan(v1.getId(), v2.getId())
  .mapEqualActivities()
  .build();

runtimeService
  .newMigration(migrationPlan)
  .processInstanceIds(Collections.singletonList(pi.getId()))
// .executeAsync()   => would perform the migration in the background
  .execute();

// Yäy, now I can prepare *and* drink coffee. I really like Camunda! :)
taskService.complete(prepareCoffeeTask.getId()); // awesome that the task has preserved id with migration :)
// drink coffee task is available:
assertNotNull(taskService.createTaskQuery().taskDefinitionKey("drink-coffe").singleResult());

The Cockpit interface for the migration (Enterprise Edition only) now uses a page flow, providing separate pages for the migration mapping, instance selection and confirmation.

  • 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...
