## 5.4.3 Performance 

The Performance pane reports the general system statistics that relate to processor (CPU) utilization, host and internal interfaces, volumes, and MDisks. You can switch between MBps or IOPS, or even drill down in the statistics to the node level. This capability might be useful when you compare the performance of each node in the system if problems exist after a node failover occurs. See Figure 5-34.

The performance statistics in the GUI show, by default, the latest 5 minutes of data. To see details of each sample, click the graph and select the time stamp, as shown in Figure 5-35.

The charts that are shown in Figure 5-35 represent 5 minutes of the data stream. For in-depth storage monitoring and performance statistics with historical data about your SVC system, use IBM Spectrum Control (enabled by former IBM Tivoli Storage Productivity Center for Disk and IBM Virtual Storage Center) or IBM Storage Insights. 

## 5.4.4 Background tasks 

This menu provides an overview of currently running tasks triggered by the administrator. In contrast to the Running jobs and Suggested tasks indication in the middle of the top pane, it does not list the suggested tasks that administrators should consider performing.
