Highlights

HotROD Demo

By popular demand, the HotROD demo is now available as a Docker image, jaegertracing/example-hotrod.

Centrally Configurable Sampling Policies

Jaeger clients have long supported centrally controlled per-service sampling policies. We are still working on rolling out full adaptive sampling to the open source version, but now the collectors allow configuring sampling strategies via a configuration file (see Sampling section in the documentation) that can be pushed to the clients without manual re-configuration of the microservices.

Running Jaeger UI Behind Reverse Proxy

Another popular request is to support running Jaeger UI with a custom site prefix, such as mycompany.com/jaeger. Now possible with the new query.base-path command line argument or the QUERY_BASE_PATH environment variable.

Google Analytics Support in the UI

If you are running a tracing team in your company, you probably want to measure how other engineers are using Jaeger. Jaeger UI supports Google Analytics, see Deployment documentation on how to configure it.

Metrics Improvements

We are still tweaking how the backend emits metrics, check the issues list below.
