For our own CUOM product we've seen rapid repeated SNMP queries and AXL
reads spike CPU and cause code yellow just as you fear.<br>
<br>
In the specific case of Nagios it caused CSCsk46770 which is a PSIRT
issue so limited information is available.<br>
<br>
<br>
I am not recommending against this approach. I am only recommending to
take inventory of system health and behavior before and after
implementation. We have repeatedly observed monitoring tools causing
significant impact.<br>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">Would you
mind elaborating on
the issues? I wouldn’t think snmp gets every few minutes would be that
big an issue (at least compared to a single get). Of course, I could
also see a
single get spiking the cpu and causing a code yellow, I just wouldn’t
expect it. Just curious cause we are using snmp to monitor our cluster.<o:p></o:p></span></p>

What do you thinks of using Nagios to monitor performance utilization
