A monitoring application for Zeebe. It is designed for developers to
- get in touch with Zeebe and workflow execution (BPMN)
- test workflows manually
- provide insides on how workflows are executed
The application imports the data from Zeebe using the Hazelcast exporter. It aggregates the data and stores it into a (in-memory) database. The data is displayed on server-side rendered HTML pages.
The docker image for the worker is published to DockerHub.
docker pull camunda/zeebe-simple-monitor:latest
- ensure that a Zeebe broker is running with a Hazelcast exporter (>= 0.8.0-alpha1)
- forward the Hazelcast port to the docker container (default:
5701) - configure the connection to the Zeebe broker by setting
zeebe.client.broker.contactPoint(default:localhost:26500) - configure the connection to Hazelcast by setting
zeebe.client.worker.hazelcast.connection(default:localhost:5701)
For a local setup, the repository contains a docker-compose file. It starts a Zeebe broker with the Hazelcast exporter and the application.
mvn clean install -DskipTests
cd docker
docker-compose up
Go to http://localhost:8082
-
Download the latest application JAR (zeebe-simple-monitor-%{VERSION}.jar )
-
Start the application
java -jar zeebe-simple-monitor-{VERSION}.jar -
Go to http://localhost:8082
The application is a Spring Boot application that uses the Spring Zeebe Starter. The configuration can be changed via environment variables or an application.yaml file. See also the following resources:
By default, the port is set to 8082 and the database is only in-memory (i.e. not persistent).

Using a different database, for example, PostgreSQL:
- change the following database configuration settings
- spring.datasource.url=jdbc:postgresql://db:5432/postgres
- spring.datasource.username=postgres
- spring.datasource.password=zeebe
- spring.datasource.driverClassName=org.postgresql.Driver
- spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
- add the database driver JAR to the classpath
- using docker, the JAR should be mounted to the
/app/libs/folder (e.g./app/libs/postgresql-42.2.12.jar)
- using docker, the JAR should be mounted to the
