text: 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: 
  
  (cid:2) CPU utilization 
  (cid:2) Port utilization and I/O rates 
  (cid:2) Volume and MDisk I/O rates 
  (cid:2) Bandwidth 
  (cid:2) Latency 
  
  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.
