JMS Bridge Docs

Observability

Starting point

JMS Bridge provides a JMX-prometheus port to build dashboards.

To enable the prometheus export in docker, set these environment variables:

  • PROMETHEUS_ENABLED=Y
  • PROMETHEUS_PORT=8888

And make sure the jmx-prometheus-javaagent/* library if copied to /usr/share/java/

Mappings from JMX beans to Prometheus counters are in observability/docker-examples/jms-bridge/image/docker/etc/jmx-prometheus-config.yml.

Examples

In the root of the present folder, the Health and Performance.json file provides a Grafana dashboard with Artemis, JVM and Kafka graphs showing the health and performance of the system.

In the docker-examples directory you will find:

  • A JMS Bridge server along with Kafka a producer and a consumer. In the provided compose file, you have to adjust line 4 to match the desired jms-bridge container image. A sample Dockerfile can be found in the jms-bridge/image folder. It needs a folder containing compiled JMS Bridge classes and configuration files (inside bin, etc, lib, share folders).

  • A full Prometheus + Grafana docker compose suite. To use:

    1. Adjust the networks section to match other docker compose containers or the location of the Kafka cluster.
    2. Connect to Grafana on port 3000. Inside the UI, make sure that the data source is named prometheus and adjust the source location if necessary. In the example docker compose JMS bridge, the Prometheus port is 8888.
    3. Import the Health and Performance.json dashboard and enjoy!
