The mmpmon command is intended for system administrators to analyze their I/O on the node on which it is run. It is not primarily a diagnostic tool, but may be used as one for certain problems. For example, running mmpmon on several nodes may be used to detect nodes that are experiencing poor performance or connectivity problems.
