Unified Manager can be integrated with OnCommand Performance Manager, to give you access to performance data. OnCommand Performance Manager provides performance monitoring and incident root-cause analysis of systems running clustered Data ONTAP software. It is the performance management part of OnCommand Unified Manager.
Performance Manager helps you identify workloads that are over-using cluster components and decreasing the performance of other workloads on the cluster. It alerts you to these performance issues, called incidents, so that you can take corrective action and return performance back to normal. You can view and analyze incidents in the Performance Manager GUI or view them in the Unified Manager Dashboard.
Performance Manager is an analytics-based IT management software solution that helps you monitor the performance of FlexVol volumes, also called user-defined workloads, and internal workload activity, called system-defined workloads, on a system running clustered Data ONTAP. All monitored volumes must be in a QoS policy group. Infinite Volumes are not supported.
Performance Manager collects and analyzes workload activity to learn the expected range, or what it perceives to be normal activity for your environment. It uses the expected range and a dynamic performance threshold to monitor the I/O response time of each volume on a cluster. A high response time indicates which volumes are performing slower than normal. Slow response time also indicates when the performance of client applications that are using a volume has decreased. Performance Manager identifies the specific cluster component that is in contention, which is the location in the cluster where the performance issue lies. Performance Manager also provides a list of suggested actions you can take to try and address any performance issues yourself.
Performance Manager collects and analyzes workload activity every 5 minutes to detect performance incidents and detects configuration changes every 15 minutes. It retains a maximum of 90 days of historical performance and event data and forecasts the expected range for all monitored workloads.
