GCP Memorystore for Redis Cluster

GCP Memorystore for Redis Cluster is a fully managed Redis service for GCP that enables applications to leverage the highly scalable, available, secure Redis service without the burden of managing complex Redis deployments.

Cisco Cloud Observability supports monitoring the following GCP Memorystore for Redis Cluster entities:

GCP Redis Cluster: A container for your data. Refers to a single GCP Memorystore for Redis Cluster unit of deployment. When provisioning a Memorystore instance, you must provision enough shards to serve the keyspace of your entire application.
Discovery Endpoint: A combination of an IP address and port number. Every instance has a discovery endpoint that you use to connect to your instance.
Private Service Connect (PSC) Connection: A private endpoint that allows secure connections to Redis Cloud databases without exposing your application's virtual private cloud.

You must configure cloud connections to monitor this entity. See Configure Google Cloud Platform Connection.

Cisco Cloud Observability displays GCP entities on the Observe page. Metrics are displayed for specific entity instances in the list and detail views.

Detail View

To display the detail view of a GCP Redis Cluster:

Navigate to the Observe page.
Under Database & Store, click GCP Redis Clusters.
The list view now displays.
From the list, click a Name to display the detail view.
The detail view displays metrics, key performance indicators, and properties (attributes) related to the GCP Redis Cluster you selected. It also displays the list and properties of the GCP Redis Cluster's Discovery Endpoints and PSC Connections.
