Step1: Deploy Kafka in Kubernetes Kafka exposes health and performance metrics via Java Management Extensions (JMX), so the first step is to enable JMX metrics on Kafka brokers. UpdateStrategy: RollingUpdate Kafka Server properties If you want to use Prometheus, you need to download and mount the JMX exporter agent JAR into the container and modify the JVM arguments to include the agent+scraper port+mbeans config file. PodManagementPolicy: OrderedReady The StatefulSet Update Strategy which Kafka will use when changes are applied: OnDelete or RollingUpdate The jmxremote.port value is also not a proper Prometheus target it's for jconsole, Visualvm, or other JMX monitoring tools, as the documentation you've linked to says. ImagePullSecrets: StatefulSet Config Start and stop pods in Parallel or OrderedReady (one-by-one.) Secrets must be manually created in the namespace. Execute below command: The yaml file looks like below and check for serviceMonitorSelector. The Prometheus created by kube-prometheus-stack is looking for a service monitor objects defined with label: release: prometheus. ImagePullPolicy: IfNotPresent Specify an array of imagePullSecrets. This tutorial describes how to use Prometheus and Java Management Extensions (JMX) to monitor a Java application running on a Google Kubernetes Engine cluster. A Prometheus, defines a desired state of Prometheus deployment. ImageTag: 5.1.0 Specify a imagePullPolicy Maybe the KSQL DB is also affected by the same issue. See this PR, which fixed it for the brokers /confluentinc/cp-all-in-one/pull/44. Declare variables to be passed into your templates. 151 2 17 I dont have any experience with KSQLDb but I submitted an issue with how JMX is handled in the docker-compose demos in the confluent repos.

The Google Kubernetes Engine ( GKE ) is responsible for controlling the. I noticed when I enable the JMX and Kafka Exporter containers for Prometheus, My HPA shows my Metric current status for memory and CPU as UKNOWN.
