Hi Everyone,
I'm having an issue and looking for some insight in how to best resolve. I'm new in implementing Solarwinds, but in the past have built a free monitoring solution from the ground up. One problem I had with device hardware, such as fans and power supplies, is that they poll via SNMP fine when operational, but return a value of N/A when I remove a unit from the device.
Two big questions that come of this:
A) If a fan or power supply actually fails (i.e. not user induced pulling of the unit), will it still alert automatically?
If not, what is the best way to monitor a change in the hardware devices? I've done trapping in the past, and know this is an option, but would like to move away from trap-based monitoring for simplicity's sake. My other thought would be to implement a "value change" threshold instead of the operational thresholds commonly used in Solarwinds. What I mean by this is if I have four fans in one chassis, and the number changes to three, then alert me. However, I can't use a "less than" statement for this, because my chassis have a varying number of members, and there for hardware components.
Any suggestions on this situation are greatly appreciated!
