Chapter 1. Distributed tracing release notes | Red Hat Product Documentation

1.1. Release notes for Red Hat OpenShift distributed tracing platform 3.0

1.1.1. Distributed tracing overview

As a service owner, you can use distributed tracing to instrument your services to gather insights into your service architecture. You can use the Red Hat OpenShift distributed tracing platform for monitoring, network profiling, and troubleshooting the interaction between components in modern, cloud-native, microservices-based applications.

With the distributed tracing platform, you can perform the following functions:

Monitor distributed transactions
Optimize performance and latency
Perform root cause analysis

The distributed tracing platform consists of three components:

Red Hat OpenShift distributed tracing platform (Jaeger), which is based on the open source Jaeger project.
Red Hat OpenShift distributed tracing platform (Tempo), which is based on the open source Grafana Tempo project.
Red Hat build of OpenTelemetry, which is based on the open source OpenTelemetry project.

1.1.2. Component versions in the Red Hat OpenShift distributed tracing platform 3.0

Operator	Component	Version

1.1.3. Red Hat OpenShift distributed tracing platform (Jaeger)

1.1.3.1. Deprecated functionality

In Red Hat OpenShift distributed tracing 3.0, Jaeger and Elasticsearch are deprecated, and both are planned to be removed in a future release. Red Hat will provide critical and above CVE bug fixes and support for these components during the current release lifecycle, but these components will no longer receive feature enhancements.

In Red Hat OpenShift distributed tracing 3.0, Tempo provided by the Tempo Operator and the OpenTelemetry collector provided by the Red Hat build of OpenTelemetry are the preferred Operators for distributed tracing collection and storage. The OpenTelemetry and Tempo distributed tracing stack is to be adopted by all users because this will be the stack that will be enhanced going forward.

1.5.3. Technology Preview features

This release introduces support for the Red Hat OpenShift distributed tracing platform (Tempo) as a Technology Preview feature for Red Hat OpenShift distributed tracing platform.

Important

The Red Hat OpenShift distributed tracing platform (Tempo) is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

The feature uses version 0.1.0 of the Red Hat OpenShift distributed tracing platform (Tempo) and version 2.0.1 of the upstream distributed tracing platform (Tempo) components.

You can use the distributed tracing platform (Tempo) to replace Jaeger so that you can use S3-compatible storage instead of ElasticSearch. Most users who use the distributed tracing platform (Tempo) instead of Jaeger will not notice any difference in functionality because the distributed tracing platform (Tempo) supports the same ingestion and query protocols as Jaeger and uses the same user interface.

If you enable this Technology Preview feature, note the following limitations of the current implementation:

The distributed tracing platform (Tempo) currently does not support disconnected installations. (TRACING-3145)
When you use the Jaeger user interface (UI) with the distributed tracing platform (Tempo), the Jaeger UI lists only services that have sent traces within the last 15 minutes. For services that have not sent traces within the last 15 minutes, those traces are still stored even though they are not visible in the Jaeger UI. (TRACING-3139)

Expanded support for the Tempo Operator is planned for future releases of the Red Hat OpenShift distributed tracing platform. Possible additional features might include support for TLS authentication, multitenancy, and multiple clusters. For more information about the Tempo Operator, see the Tempo community documentation.
