The Swap Alert
Name:
swap
Function:
To detect a swapping or paging bottleneck.
Description:
This alert is triggered whenever the system develops a swapping or paging bottleneck. It measures the number of blocks swapped or paged to disk, as a percentage of the maximum disk throughput. As any significant swapping or paging activity is very detrimental to system performance, the threshold percentage should be set quite low.
