Display the high-availability interconnect device performance statistics

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The system ha interconnect statistics performance show command displays the high-availability interconnect device performance statistics.

Parameters

{ [-fields <fieldname>,…​]

If you specify the -fields <fieldname>,…​ parameter, the command displays only the fields that you specify.

| [-instance ] }

Use this parameter to display all the fields from all nodes in cluster.

[-node {<nodename>|local}] - Node (privilege: advanced)

Use this parameter to display all the fields from the specified node in the cluster.

[-elapsed <integer>] - Elapsed Time (secs) (privilege: advanced)

Selects the nodes that match this parameter value. Displays the total elapsed time between statistics collection start time to end time. During the initialization stage, statistics collection starts when the partner node is up and ready. After the initialization stage, the statistics collection start time is reset after every execution of this command. This means that after the initialization stage, elapsed time represents the time between current command execution and previous command execution.

[-qmax-wait <integer>] - Maximum Queue Wait Count (privilege: advanced)

Selects the nodes that match this wait value. The queue maximum wait value is the total number of times the interconnect device waited to post requests on the send queue.
