OnCommand Performance Manager provides performance monitoring and incident root-cause analysis for systems running clustered Data ONTAP software. It is the performance management part of OnCommand Unified Manager.
Performance Manager helps you identify workloads that are overusing cluster components and decreasing the performance of other workloads on the cluster. It alerts you to these performance events, called incidents, so that you can take corrective action and return performance back to normal operation. You can view and analyze incidents in the Performance Manager GUI or view them in the Unified Manager Dashboard.
Performance Manager monitors the performance of two types of workloads:
These workloads consist of FlexVol volumes that you have created in your cluster.
These workloads consist of internal system activity.
