Kuma 0.4 Released With L7 Tracing + Grafana Dashboards!

We are happy to announce the release of Kuma 0.4! This is a major release focused on significantly better observability capabilities that also includes many new features and improvements across the board.

This release also marks the 10th release of Kuma since September 2019! We are very proud of the release momentum we have executed so far, and we are looking forward to accelerating the delivery of more advanced L7 features within the next few months, as well as more advanced networking support for complex service mesh deployments across hybrid environments.

Notable Features

  • A new TrafficTrace policy that allows users to configure tracing on L7 HTTP traffic
  • Three official Grafana dashboards to visualize traffic metrics collected by Prometheus
  • For Kubernetes, a new selective sidecar injection capability
  • For Universal deployments, a new data plane format to better support gateway use cases
  • A new protocol tag to support different L7 protocols
  • And much more!

For a complete list of features and updates, take a look at the full changelog.

L7 Tracing

Kuma now supports L7 tracing with configurable tracing backends by leveraging the new TrafficTrace policy. It supports Zipkin and Jaeger out of the box, and it allows users to better identify the flow of traffic among our services in order to identify dependencies and bottlenecks in our systems.

Below you can see a Jaeger example after being integrated with Kuma:

Grafana Dashboards

Kuma already allowed the collection of metrics via the TrafficMetric, and now it supports three new official Grafana dashboards that, out of the box, allow you to visualize vital metrics about the service mesh. The dashboards provide:

  • Metrics for a single data plane
  • Metrics for a single mesh
  • Metrics for the service traffic in a mesh

You can find the dashboards in the Grafana marketplace. Below, you see an example:

As we keep adding more and more features in Kuma and work with the broader community, don’t forget to check out the Community resources, including a real-time Slack chat to get an answer to any question you may have when using Kuma.

Kuma’s goal is to create a simple, portable and feature-rich service mesh that everybody can use in minutes across any system. Contributions are welcome to get one step closer to this vision on every new release.


Be sure to carefully read the Upgrade Guide, as this new version introduces a few important changes.
