Chapter 1. Release notes for the Red Hat OpenShift Distributed Tracing Platform 3.8
1.1. About this release
Distributed Tracing Platform 3.8 is provided through the Tempo Operator 0.19.0 and based on the open source Grafana Tempo 2.9.0.
Only supported features are documented. Undocumented features are currently unsupported. If you need assistance with a feature, contact Red Hat’s support.
1.2. Fixed issues
- Resolved issue with TLS certificates affecting Tempo pods
Before this update, the Tempo pods would stop to communicate because internal TLS certificates were renewed. With this update, the Tempo pods automatically restart when certificates are renewed.
- Tempo query frontend no longer fails to fetch trace JSON
Before this update, clicking on Trace in the Jaeger UI and refreshing the page, or accessing Trace
Trace Timeline Trace JSON from the Tempo query frontend, might result in the Tempo query pod failing with an EOF error. With this update, this issue is resolved.
Some linked Jira tickets are accessible only with Red Hat credentials.
