## 11.13 Performance monitoring 

You can monitor storage system performance to evaluate workload processing and response times. To monitor performance, complete these steps: 

1. From the System window, select the Monitoring icon. 

2. Click Performance to display graphs that track performance indicators. The performance indicators include I/O operations per second (IOPS), latency, bandwidth, cache read hits, and write delays. 

3. The Performance window includes four preset graphs, which are listed in the Favorites menu. These pre-configured graphs can be seen by clicking on the Favorites menu icon, as shown in Figure 11-124. You also have the option to set any of these graphs as the default.

4. You can create your own performance graphs for the storage system, pools, and fibre channel ports. You can use predefined graphs and compare performance statistics for multiple pools or fibre channel ports.
