especially a slow one. Nagios generally concerns itself with the status of some
measured value at the time of the check. You can check the amount of available
memory, and report back if the total free memory is less than some
threshold, but there is no plugin that checks the status of memory over
time.<BR><BR><PRE class=moz-signature cols="72">--
