Use the sar -w command to report swapping and switching activity.
$ sar -w 00:00:00 swpin/s bswin/s swpot/s bswot/s pswch/s 01:00:00 0.00 0.0 0.00 0.0 22 |
The following list describes target values and observations related to the sar -w command output.
The number of LWP transfers into memory per second.
The number of blocks transferred for swap-ins per second. /* (float)PGTOBLK(xx->cvmi.pgswapin) / sec_diff */
The average number of processes that are swapped out of memory per second. If the number is greater than 1, you might need to increase memory.
The number of blocks that are transferred for swap-outs per second.
The number of kernel thread switches, per second.
All process swap-ins include process initialization.
The following example shows output from the sar -w command.
