<p class=MsoNormal>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:#1F497D'>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.</span><o:p></o:p></p>

<p class=MsoNormal>It is possible but I would caution you to take careful
inventory of functionality and alarms before and after implementing
nagios. we have seen numerous service impacting issues caused by
monitoring tools.<br>
