juju deploy kafka --channel 3/stable
You will need Juju 2.9 to be able to run this command. Learn how to upgrade to Juju 2.9.
Deploy universal operators easily with Juju, the Universal Operator Lifecycle Manager.
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.
