Metrics
Access metrics for Redis Cluster
To fetch the above listed metrics for Redis Cluster deployments in PDS, you can connect to the metrics exporter using the following details:
Metrics port
The data service metrics are accessible on port 9121 for both Redis and Redis Cluster deployments.
Access metrics
To access the metrics from outside the Kubernetes cluster:
-
Use the
kubectl port-forwardcommand to forward the metrics port (9121) to your local machine. For example:kubectl port-forward <redis-cluster-pod-name> 9121:9121 -n <namespace>Replace
<redis-cluster-pod-name>with the name of your Redis Cluster pod and<namespace>with the appropriate namespace. -
Once the port-forwarding is active, access the metrics by navigating to the following URL in your browser or API client:
http://localhost:9121/metrics
note
Ensure that the metrics port is open and accessible within your cluster’s networking configuration.
