NPM has it available, it would be nice to use it with SAM as I dont have licensing for NPM and would like to be able to add my UPS and wethergoos to alerts.
If you have SAM:
Universal Device Pollers are available as part of NPM and Device Studio is part of the Orion Platform ( Orion Platform features available in SAM )
Device studio is shipped with SAM standalone and if you need something similar to undp, I agree with Jamison's comment that the SNMP component monitor is the way to go.
