JMPstat

JMPstat is a tabular display of per-processor statistics, almost identical to the mpstat command.

The fields displayed are:

• CPU: the processor id
• minf: minor faults
• mjf: major faults
• xcal: inter-processor cross-calls
• intr: interrupts
• ithr: interrupts as threads (not counting clock interrupts)
• csw: context switches
• icsw: involuntary context switches
• migr: thread migrations (to another processor)
• smtx: spins on mutexes (lock not acquired on first try)
• srw: spins on readers/writer locks (lock not acquired on first try)
• syscl: system calls
• usr: percent user time
• sys: percent system time
• idl: percent idle time

The I/O wait time is not shown, as in Solaris 10 it is no longer calculated and will always return zero.

The rows can be sorted by selecting the column header.

The toolbar

The toolbar contains a small number of menus.

• File - allows you to exit jmpstat.
• Update every - allows you to set how rapidly the statistics are updated.
• Help - shows this help file, and the CDDL license that this software is licensed under.
