Using Cacti To Monitor Modems, How to monitor modem stats, line quality, etc Options

[Demosthenes]

I have found an interesting thread on the Cacti forum suggesting how to use Cacti to monitor Billion modems. I have installed Cacti on my Ubuntu system and it seems to be working as it's graphing my memory load out of the box. Not sure what else Cacti can do though.

Installed the template and getting the following in debug mode as no data was returned. Anyone else have any luck with Cacti or can suggest better methods to monitor a Billion modem?

I have used the mrtg method under http://au.billion.com/forums/index.php?showtopic=4309 for some time although I heard Cacti is better so though I would give it a shot.

I am using Naked ADSL so it is very important to keep an eye on line quality and uptime.

On another node did anyone ever work out how to save the modem log to disk and monitor specific aspects such as the firewall?

From memory, the OIDs in the template aren't quite right (one of the numbers is one out.)

The OIDs I'm using are:
Downstream Attenuation: .1.3.6.1.2.1.10.94.1.1.2.1.5.3
Downstream SNR: .1.3.6.1.2.1.10.94.1.1.2.1.4.3
Downstream Speed: .1.3.6.1.2.1.10.94.1.1.4.1.2.3
Upstream Attenuation: .1.3.6.1.2.1.10.94.1.1.3.1.5.3
Upstream SNR: .1.3.6.1.2.1.10.94.1.1.3.1.4.3
Upstream Speed: .1.3.6.1.2.1.10.94.1.1.5.1.2.3

Thanks for this - I have linked this back to the Cacti forum and the below forum after the below response over there:

"These are for my 7404R2, I doubt they've changed, but it's possible.

Upstream: .1.3.6.1.2.1.10.94.1.1.3.1.5.3

You might also find these useful:

Modem Uptime (time since boot): .1.3.6.1.2.1.1.3.0"

now I'm getting this out of debug for the attenuation graph - I think broke something else in Cacti..

All working in Cacti now - tool of choice! Now I just need to work out how to enter the other templates such as connect time, and do other cool stuff with Cacti

Relatedly to the above - can anybody tell me the OID for Line Speed on a 7800n?
Alternatively, can somebody tell me what numbers I would expect to find in the output of snmpwalk for a given up and down linespeed on a modem with a known OID?

To explain, I have attempted to capture linespeed on a 7800n using the OID .1.3.6.1.2.1.10.94.1.1.4.1.2.3
This is not the correct OID for a 7800n.

I also tried doing an snmpwalk, and looking through the output for a number that matched the linespeed reported in the web interface.
My current linespeed, according to the web interface is 734 / 13478 kbps - but neither of these numbers appear in the output.
Accordingly, I assume that there must be a multiplier or similar - could somebody with another modem tell me if they are aware of a multiplier?

Thanks!
