diagnose -n

(Maui Node Diagnostics)

Synopsis:

diagnose -n [ -t <PARTITION>] [ -v ] [<NODENAME>]

Overview:

The 'diagnose -n' command provides detailed information about the state of nodes Maui is currently tracking.  This command also performs a large number of sanity and state checks.  The node configuration and status information as well as the results of the various checks are presented by this command.

Flags:

-n (nodes)diagnose node information
-t <PARTITION>(partition) show only nodes contained in the specified partition
-v (verbose)do not truncate data fields

Output:

This command presents detailed node information in whitespace delineated fields.

A few upfront notes about this command.  First, the output of this command is VERY long.  You will need to have a wide window or will need to mentally 'unwrap' the output.  Second, it is important to note that a number of fields will contains truncated outputs by default (ie, the 'Classes' column is truncated at 20 characters).  You will need to use the '-v' flag to see the entire field content.
