Redis®* Cache is an open-source and in-memory data store. You must add the Redis exporters to your deployment to view Redis Cache. See Configure Redis.
AppDynamics Cloud displays Redis entities on the Observe page. Metrics display for specific entity instances in the list and detail views.
Clicking an Instance Name displays the metric details for the selected cache. The detail view displays metrics, key performance indicators, and properties (attributes) that relate to the cache you selected.
