Wireless Data

[bob]

Im trying to monitor some wireless links and collect data from them (signal, and noise). I can't seem to get Cacti to work for some reason, its not even pulling any data. I have double checked my OID and SNMP string and even verified it works with another application but its still not pulling any data. The values im getting are just 0 (not NAN) Here is my source:

Another thing, how does it know what interface to look at for the wireless information? Like in MRTG it gives me data on the ethernet and wireless interface.

I'm afraid I don't have the solution to your problem, but out of curiousity, what OID are you using to get this information?

[bob]

Im using:

1.3.6.1.4.1.762.2.5.2.1.8 (for noise)
1.3.6.1.4.1.762.2.5.2.1.7 (for signal)

These OID's are for KarlBridge radios.

Can you post the output of snmpet on these OIDs? I know with my wireless product, the signal and noise values are returned as strings, which cacti didn't really appreciate, so I had to write a script to regex out the values.

I use Solectek Skyway wireless router, so its no doubt different, but its a thought.
