juju deploy kafka --channel 3/stable
The Charmed Kafka Operator comes with the JMX exporter.
The metrics can be queried by accessing the
Additionally, the charm provides integration with the Canonical Observability Stack.
Deploy cos-lite bundle in a Kubernetes environment. This can be done by following the deployment tutorial. Since the Charmed Kafka Operator is deployed on a machine environment, it is needed to offer the endpoints of the COS relations. The offers-overlay can be used, and this step is shown in the COS tutorial.
Switch to COS K8s environment and offer COS interfaces to be cross-model related with Charmed Kafka VM model:
# Switch to Kubernetes controller, for the cos model. juju switch <k8s_controller>:<cos_model_name> juju offer grafana:grafana-dashboard grafana-dashboards juju offer loki:logging loki-logging juju offer prometheus:receive-remote-write prometheus-receive-remote-write
Switch to Charmed Kafka VM model, find offers and relate with them:
# We are on the Kubernetes controller, for the cos model. Switch to mysql model juju switch <machine_controller_name>:<kafka_model_name> juju find-offers <k8s_controller>:
A similar output should appear, if
k8s is the k8s controller name and
cos the model where
cos-lite has been deployed:
Store URL Access Interfaces k8s admin/cos.grafana-dashboards admin grafana_dashboard:grafana-dashboard k8s admin/cos.loki-logging admin loki_push_api:logging k8s admin/cos.prometheus-receive-remote-write admin prometheus-receive-remote-write:receive-remote-write ...
Consume offers to be reachable in the current model:
juju consume k8s:admin/cos.prometheus-receive-remote-write juju consume k8s:admin/cos.loki-logging juju consume k8s:admin/cos.grafana-dashboards
grafana-agent (subordinate charm) and relate it with Charmed Kafka, later relate
grafana-agent with consumed COS offers:
juju deploy grafana-agent juju relate kafka:cos-agent grafana-agent juju relate grafana-agent grafana-dashboards juju relate grafana-agent loki-logging juju relate grafana-agent prometheus-receive-remote-write
After this is complete, Grafana will show the new dashboards:
Kafka Exporter and allows access for Charmed Kafka logs on Loki.
