Jaeger vs Zipkin for Istio¶
Both Jaeger and Zipkin are distributed Tracing systems compatible with Istio, designed to help users monitor and troubleshoot transactions within complex service architectures^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
Overview and Purpose¶
These tools are essential for utilizing Istio's observability features, although they are not part of the Istio core^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. They function by gathering timing data needed to troubleshoot latency problems and monitor distributed transactions^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
Jaeger¶
Jaeger is an open-source, end-to-end distributed Tracing system^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. It is particularly useful for performing root cause analysis, service dependency analysis, and performance or latency optimization^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. In the context of Istio, Jaeger is tightly integrated with [[Kiali]] to provide distributed Tracing visualization directly from the Service mesh console^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
Deployment¶
Jaeger is the default distributed Tracing addon in the provided sample configurations^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. To deploy it, users typically apply the standard addons configuration^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
Zipkin¶
Zipkin is also a distributed Tracing system that helps in gathering timing data to troubleshoot latency issues^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. Istio supports Zipkin as an alternative to Jaeger^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
Deployment¶
Zipkin is not deployed by default in Istio sample configurations^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. To use Zipkin instead of Jaeger, you must manually deploy it using the command:
kubectl apply -f samples/addons/extras/zipkin.yaml^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
If Jaeger is already installed, it is recommended to remove the unused deployment with kubectl delete deployment jaeger to avoid conflicts or resource waste^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md]. Alternatively, you can follow selective installation steps to deploy only the specific addons required^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
Comparison Summary¶
- Integration: Jaeger features a direct integration with the [[Kiali]] observability console, whereas Zipkin does not have this specific integration mentioned^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
- Default Selection: Jaeger is the default Tracing option for Istio sample deployments, while Zipkin is considered an "extra" requiring explicit installation^[400-devops__07-Monitoring-and-Observability__k8s-istio__samples__addons__README.md].
