View Sharded Clusters
On this page
A sharded cluster is the set of nodes comprising a sharded MongoDB deployment. To view the metrics for a specific Ops Manager deployment in a project, click the Metrics button for that deployment. Alternatively, click on the name of the deployment to open the deployment overview, then click the Metrics tab.
Monitor deployment metrics to identify performance issues and determine whether your current deployment meets your requirements. To learn more about the metrics available to monitor your deployments, see Review Available Metrics.
The Metrics view has three distinct sections:

As a result, when rendering metrics for large deployments over a long period of time, Ops Manager may display metrics at a lower granularity than is retained. For example, for Premium Ops Manager users, Ops Manager retains data for the past
year with a granularity of 1 hour. A year's worth of data
results in The granularity at which Ops Manager gathers and stores metric data depends on your Ops Manager plan. |
