Performance pane

You can monitor real-time performance of a storage system or active/active pair using the four graphs of the Performance pane. You can also manipulate the interface to view the graphs as percentages.

How Performance pane monitoring works

Monitoring is started when you select a storage system or a pair of storage systems and the corresponding dashboard is loaded. Monitoring and graphing continue until you choose another storage system or active/active pair of storage systems and load its dashboard.

You can click

at the top of the Performance pane to see a four-panel display of numbers and percentages for the monitored values rather than graphs. You can also hover the cursor over any of the four graphs to see a legend with exact percentages or numbers for that graph.

Performance pane for individual storage systems

The following table lists and describes the graphs that are displayed in the Performance pane for individual storage systems.

Graph name	Description
CPU	The system CPU percent busy
I/O	The network I/O throughput and the disk I/O throughput
Protocol Ops	The iSCSI operations per second (if licensed), the CIFS operations per second (if licensed), and the NFS operations per second (if licensed)
Protocol Latencies	The iSCSI latencies (if licensed), the CIFS latencies (if licensed), and the NFS latencies (if licensed)

Performance pane for active/active pairs

The following table defines the graphs that are displayed in the Performance pane for active/active pairs.

Graph name	Description
CPU	The highest node CPU percent busy
I/O	The node summation of network I/O throughput and the node summations of disk I/O throughput
Operations	The node summation of iSCSI operations per second (if licensed), the node summation of CIFS operations per second (if licensed), and the node summation of NFS operations per second (if licensed)
Latency	The highest node iSCSI latency (if licensed), the highest node CIFS latency (if licensed), and the highest NFS latency (if licensed)
