Has anyone any experience about how to pull 3G SNR (Signal to Noise Ratio) from Cisco 881g 3G Router with Nagios Core? I've been trying to accomplish that for a few days now but can't seem to find suitable MIBs. I found one MIB for it:
Specific Object Information
Type C3gEcIo
Status current
Range -150 - 0
MIB CISCO-WAN-3G-MIB ; - View Supporting Images
Description Generic EcIo range.
So I would assume that the -150 value is correct and you just have very little noise in your device's band.

Hmm.. I wonder if there is any way to monitor the actual "current SNR" value? Fortunately, i've managed to work out the signal strength but it would be perfect to have the SNR monitored besides that also..
GSM/Ec/IO is about as close to SNR as you will get for that MIB. The oid you posted does report current values, but will not report values lower than -150 dB. You could just have so little noise in your band that the oid reports the lowest value possible.
