Jaeger overview

As a service owner, you can use Jaeger to instrument your services to gather insights into your service architecture. Jaeger is an open source distributed tracing platform that you can use for monitoring, network profiling, and troubleshooting the interaction between components in modern, cloud-native, microservices-based applications.

Using Jaeger lets you perform the following functions:

  • Monitor distributed transactions

  • Optimize performance and latency

  • Perform root cause analysis

Jaeger is based on the vendor-neutral OpenTracing APIs and instrumentation.

Making open source more inclusive

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Getting support

If you experience difficulty with a procedure described in this documentation, or with OpenShift Container Platform in general, visit the Red Hat Customer Portal. From the Customer Portal, you can:

  • Search or browse through the Red Hat Knowledgebase of articles and solutions relating to Red Hat products.

  • Submit a support case to Red Hat Support.

  • Access other product documentation.

To identify issues with your cluster, you can use Insights in Red Hat OpenShift Cluster Manager. Insights provides details about issues and, if available, information on how to solve a problem.

If you have a suggestion for improving this documentation or have found an error, please submit a Bugzilla report against the OpenShift Container Platform product for the Documentation component. Please provide specific details, such as the section name and OpenShift Container Platform version.

Technology Preview

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 https://access.redhat.com/support/offerings/techpreview/.

OpenShift Jaeger 2.0.0 Technology Preview 1

When you install the Jaeger Operator you can select a Technology Preview version of Jaeger. This gives you access to clients and infrastructure for exporting tracing data to Jaeger based on the OpenTelemetry framework. Note that this version is not supported for production environments.

The OpenTelemetry collector allows developers to instrument their code with vendor agnostic APIs, avoiding vendor lock-in and opening the door to a growing ecosystem of observability tooling.

Jaeger known issues

These limitations exist in Jaeger:

  • Apache Spark is not supported.

  • Jaeger streaming via AMQ/Kafka is unsupported on IBM Z and IBM Power Systems.

These are the known issues in Jaeger:

  • BZ-1918920 The Elasticsearch pods does not get restarted automatically after an update. As a workaround, restart the pods manually.

  • TRACING-809 Jaeger Ingester is incompatible with Kafka 2.3. When there are two or more instances of the Jaeger Ingester and enough traffic it will continuously generate rebalancing messages in the logs. This is due to a regression in Kafka 2.3 that was fixed in Kafka 2.3.1. For more information, see Jaegertracing-1819.

Jaeger fixed issues

  • TRACING-1725 Follow-up to TRACING-1631. Additional fix to ensure that Elasticsearch certificates are properly reconciled when there are multiple Jaeger production instances, using same name but within different namespaces. See also BZ-1918920.

  • TRACING-1631 Multiple Jaeger production instances, using same name but within different namespaces, causing Elasticsearch certificate issue. When multiple service meshes were installed, all of the Jaeger Elasticsearch instances had the same Elasticsearch secret instead of individual secrets, which prevented the OpenShift Elasticsearch Operator from communicating with all of the Elasticsearch clusters.

  • TRACING-1300 Failed connection between Agent and Collector when using Istio sidecar. An update of the Jaeger Operator enabled TLS communication by default between a Jaeger sidecar agent and the Jaeger Collector.

  • TRACING-1208 Authentication "500 Internal Error" when accessing Jaeger UI. When trying to authenticate to the UI using OAuth, I get a 500 error because oauth-proxy sidecar doesn’t trust the custom CA bundle defined at installation time with the additionalTrustBundle.

  • TRACING-1166 It is not currently possible to use the Jaeger streaming strategy within a disconnected environment. When a Kafka cluster is being provisioned, it results in a error: Failed to pull image registry.redhat.io/amq7/amq-streams-kafka-24-rhel7@sha256:f9ceca004f1b7dccb3b82d9a8027961f9fe4104e0ed69752c0bdd8078b4a1076.
