Generate automated Grafana metrics dashboards for MicroProfile apps

Generate automated Grafana metrics dashboards for MicroProfile apps

Grafana is an awesome visualization tool for seeing real-time metrics from your applications, and you can combine it with MicroProfile and similar tools to create one dashboard for multiple projects. Different projects use different names for metrics, however, so it is often necessary (and tedious) to handcraft the metrics for each project. Moreover, each project can expose its own custom metrics, and each MicroProfile vendor can also produce custom metrics, so there are many manual steps involved if you want to see all of your metrics in one place.

What if you could simply examine a running app and generate a dashboard with all of its exposed metrics? That is exactly what you can do with the MicroProfile Metrics Generator, a new open source tool that I created to dynamically generate Grafana dashboards for any MicroProfile project by capturing and monitoring all of your project metrics. Once you’ve created a dashboard, you can use it with Grafana, customize it to suit specific needs, and save it as a JSON file. You can also periodically regenerate your dashboards to bring in new metrics that you’ve exposed in your application.

In this article, you will learn how to do just that: Use the MicroProfile Metrics Generator to create a unified dashboard for all of your project’s metrics.

Red Hat support for Node.js

Red Hat support for Node.js

Node.js Foundation Logo

For the past two years, Red Hat Middleware has provided a supported Node.js runtime on Red Hat OpenShift as part of Red Hat Runtimes. Our goal has been to provide rapid releases of the upstream Node.js core project, example applications to get developers up and running quickly, Node.js container images, integrations with other components of Red Hat’s cloud-native stack, and (of course) provide world-class service and support for customers. Earlier this year, the team behind Red Hat’s distribution and support of Node.js even received a “Devie” award from DeveloperWeek for this work, further acknowledging Red Hat’s role in supporting the community and ecosystem.

Red Hat Node.js experts at your fingertips

Red Hat collaborates in more ways than one with the fastest growing runtimes used in business-critical applications on the cloud by contributing to the community, being part of the Technical Steering Committee, and even participating and driving strategic initiatives to carve the future of Node.js. Combining this work with our Red Hat Enterprise Linux (RHEL) and OpenShift expertise, we can help you reach your goals of delivering and supporting business-critical applications on and off the cloud.
