by | 23.09.2021 | Changelog

Jaeger v1.26.0 recently came. It has a few changes in its backend. In this article, we will cover all of this in a straightforward way. We will see all of the fixes and the new features that the devs have added.

Let’s start!

What is Jaeger?

Jaeger is a graduated CNCF project. It is a distributed tracing platform developed by Uber Technologies after getting inspiration from Dapper and OpenZipkin. Gradually it is donated to Cloud Native Computing Foundation.

We can use Jaegar for many practical purposes, such as monitoring microservices-based distributed systems, distribution of context propagation and transaction monitoring. It also helps in the analysis of root cause and service dependency. It helps optimize the performance and reduces the latency.

New Features

Version 1.26.0 of Jaegar brings the addition of Cassandra v4 support. It also adds the es-index-cleaner golang implementation for Jaegar. We can also see the addition of the CLI Option for gRPC Max Receive Message Size. With the latest release, Jaegar will be able to detect the OpenSearch version automatically. Also, we can observe the addition of SendGetBodyAs on elasticsearch. Furthermore, we can see the setting of lookback in ES rollover to distant past.

Bug fixes and Minor Improvements

The latest release will now check for invalid –agent.tags. Also, the release will replace old linters with golangci-lint. We can also see a fixing of the panic on the empty findTraces query. Also, we see the upgradation of Go lang support to v1.17. There is also the addition of docker buildx make target. Again, we see the fixing of the name for elasticsearch integration tests. Furthermore, we can see the upgradation of ES images in integration tests. As for UI changes, with the latest version, the UI got pinned to version 1.16.0.


So far, we have seen how the minor changes and some new features will help users get a better experience with Jaeger. It will be beneficial as you will be able to use Jaeger without any hindrance. I know you want to try it out too. You can download it from here and if you want to contribute to the project, visit here. Have a great sandbox experience with Jaeger until next time.
