Load average (current load) is the average number of processes that are
ready to run, averaged over 1, 5 and 15 minutes. Load average has
nothing to do with memory utilization.<br>
<br>
There is no way to directly detect a memory leak... 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>
