How to Check Interprocess Communication (sar)
Use the sar -m command to report interprocess communication activities.
$ sar -m SunOS venus 5.6 Generic sun4m 08/20/96 00:00:03 msg/s sema/s 01:00:02 0.00 0.05 |
These figures will usually be zero (0.00), unless you are running applications that use messages or semaphores.
The output from the -m option is described in Table 64-13.
