In this section, we will use Kiali together with Jaeger to observe what's going on in the service mesh. For performance monitoring using Grafana, refer to Chapter 20, Monitoring Microservices.
Before we do that, we need to get rid of some noise created by the health checks performed by Kubernetes' liveness and readiness probes. In the previous chapters, they have been using the same port as the API requests. This means that Istio will collect telematics data for both health checks and requests sent to the API. This will cause the graphs shown by Kiali to become unnecessarily cluttered. Kiali can filter out traffic that we are not interested in, but a simpler solution is to use a different port for the health checks.
Microservices can be configured to use a separate port for requests sent to the actuator endpoints...
