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: Real-time statistics are not a configurable option and cannot be disabled.  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.
