paging out or not?

paging out or not?


I would like to run a script on several servers to determine whether or not the servers are paging out to disk (are in swap trouble). What command would give me that information (text based)?

Thanks in advance

Re: paging out or not?

use the vmstat command. The values under the pi and po columns are paging in and out. If these values are ever > 5 or more then you are paging. < 5 is ok, a normal system will have the odd 1 or 2 every once in a while.

Re: paging out or not?

Hi Dan,

Use vmstat. A combination of vmstat and awk will give up just the data you need.

Man vmstat for details.

If it ain't broke, I can fix that.
