744 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
As with system statistics, node statistics help you to evaluate whether the node is operating 
within normal performance metrics.
Real-time performance monitoring gathers the following system-level performance statistics:
/SM590000CPU utilization
/SM590000Port utilization and I/O rates
/SM590000Volume and MDisk I/O rates
/SM590000Bandwidth
/SM590000Latency
Real-time statistics are not a configurable option and cannot be disabled. 
Real-time performance monitoring with the CLI
The lsnodecanisterstats and lssystemstats commands are available for monitoring the 
statistics through the CLI. 
The lsnodecanisterstats command provides performance statistics for the nodes that are 
part of a clustered system, as shown in Example A-4. The output is truncated and shows only 
part of the available statistics. You can also specify a node name in the command to limit the 
output for a specific node.
