<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The load is number of tasks in the runque. In my head, to utilize your resources perfectly, the value 1 for single CPU would be good, since than
there should be minimal delay, but still there is always something to do for the CPU. If the value are > 1 for a single cpu, than there will be wait time for tasks to be done. This is not necessary an issue, depending on what the machine is used for, and the
world is not perfect, so this will not always be the same. Therefor it also is an average value we are monitoring. A long que for a short time is normal and the reason we have ques. Problem is if the que over time is longer than the cpu can process giving
delay and degraded performance. Again, what is acceptable for one machine is depending on the tasks it shall do.<o:p></o:p></span></p>

server. A load of 5 is hardly breaking a sweat. In some cases, high load doesn't even affect the system and you wouldn't want to be notified until a normally unreasonably high value. I'd suspect 10.0 15.0 for your system or 15.0 20.0 might not be a bad guess.<br>

Is correct the default params that appear on "analysis.cfg" for chect the cpu load in case that the server have 4 cores (intel xeon 1230)?, can i use this values for anyone CPU types?<br>
