Prometheus supports scraping multiple instances of an application. Applications that run in orchestrated environments require to be discovered dynamically, since their IP addresses will change. Prometheus can be configured to use the Kubernetes API to discover changes in the list of running instances dynamically.<\/p>\n

The following shows a minimalistic Prometheus example of instrumenting an application with multiple pod instances.<\/p>\n

Prometheus configuration<\/strong><\/p>\n

We configure Prometheus to discover the pods of our config-example<\/code> application.<\/p>\n

Instrumented application<\/strong><\/p>\n

This example uses the MicroProfile Metrics endpoint that runs on top of Open Liberty. The application exposes the metrics in the Prometheus format under port 9443<\/code> and path \/metrics\/<\/code>.<\/p>\n

Prometheus setup & RBAC<\/strong><\/p>\n

In order to make the example work for a RBAC Kubernetes setup, the Prometheus service account needs to have the correct permissions. Therefore, we create a service account and corresponding cluster roles as included in the YAML definitions here<\/a>. Similarly, we specify the service account when creating the Prometheus deployment.<\/p>\n

We create a deployment and service for our Prometheus instance.<\/p>\n

We can see the actual targets including their IP address under the Prometheus configuration.<\/p>\n

\n
\"Kubernetes<\/figure>\n<\/div>\n

Have a look at the full example on GitHub<\/a>. You might also see the following video<\/a> how to implement business metrics in Java EE applications using MicroProfile.<\/p>\n

For more complex microservice examples that define many more applications, this approach using the plain Prometheus configuration might be a bit cumbersome. To minimize boilerplate code, developers can use solutions that abstracts away the lower-level configuration, such as Prometheus Operator<\/a>. In the next post we\u2019ll see how Prometheus Operator facilitates the configuration of applications.<\/p>\n

Happy monitoring!<\/p>\n
