View insights from Azure Monitor
You can access Azure Cache for Redis insights from the Insights Hub of Azure Monitor.
To view the utilization and performance of your Azure Cache for Redis instances across all of your subscriptions, do the following steps:

Workbooks
Azure Cache for Redis insights are based on the workbooks feature of Azure Monitor that provides rich visualizations for metrics and other data. Azure Cache for Redis insights provides two workbooks by default:
Azure Cache For Redis Resource Overview combines many of the most commonly used metrics so that the health and performance of the cache instance can be viewed at a glance.
Geo-Replication Dashboard pulls geo-replication health and status metrics from both the geo-primary and geo-secondary cache instances to give a complete picture of geo-replcation health. Using this dashboard is recommended, as some geo-replication metrics are only emitted from either the geo-primary or geo-secondary.
Overview
On Overview, the table displays interactive Azure Cache for Redis metrics. You can filter the results based on the options you select from the following drop-down lists:
Subscriptions: Only subscriptions that have an Azure Cache for Redis resource are listed.
Azure Cache for Redis: You can select all, a subset, or a single Azure Cache for Redis resource.
Time Range: By default, the table displays the last four hours of information based on the corresponding selections.
There's a counter tile under the drop-down lists. The tile shows the total number of Azure Cache for Redis resources in the selected subscriptions. Conditional color codes or heat maps for workbook columns report transaction metrics. The deepest color represents the highest value. Lighter colors represent lower values.
