How to Check Interprocess Communication (sar -m)

1. Use the sar -m command to report interprocess communication activities.

   $ sar -m 00:00:00 msg/s sema/s 01:00:00 0.00 0.00

   These figures are usually zero (0.00), unless you are running applications that use messages or semaphores.

   The following list describes the output from the -m option.

   msg/s

   The number of message operations (sends and receives) per second

   sema/s

   The number of semaphore operations per second
