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 table describes target values and observations.
Table 24–19 Output From the sar -w Command
Field Name |
Description |
---|---|
swpin/s |
The number of LWP transfers into memory per second. |
bswin/s |
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. |
swpot/s |
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. |
bswot/s |
The number of blocks that are transferred for swap-outs per second. |
pswch/s |
The number of kernel thread switches, per second. |
All process swap-ins include process initialization.
