Did you figure out how to graph signal strength?

I have had luck setting up the data source as a function instead of an SNMP OID and using a call like this:

oid("iso.org.dod.internet.private.enterprises.99.5.101.1")

Not that this will be your oid but you get the idea.
Hope it helps...

Hi guys,

Maybe an idea here : why not graph the ping quality with a sensible equipment on the wireless lan ? It is not the response to your question, but gives an idea of the signal quality.

Hope this helps,

Thanks innova,
Using function as you described, helped me, with another oid.
Here is my steps to make the nice graphs for signal strength:
1. Identified the oid that represents the signal strength (snmpwalk)
iso.org.dod.internet.private.enterprises.1240.2.3.4.7.3.12.0.
2. Added a new function. Name=SignalStrength and code=oid("iso.org.dod.internet.private.enterprises.1240.2.3.4.7.3.12.0").
3. Added a new probe. Type=Function, Available=SignalStrength() > 0, Error="", Value=SignalStrength(), Unit=%.
4. Under Services for every wlan-unit, I added the new probe.
5. Added a new Chart just for wireless units (signalstrength graphs), and added all the new SignalStrength services just made in step 4.
Works very nice!

Hi There,

I have seen the same odd numbers presented in v3.0b3, but there is a way around it. Latest stable version seems ok.

I described it in this new wiki I made:
