Templates to Cisco uBR (SNR, FEC, Modems Ups, Interf Utiliz)

[Spark]

Hi,
Sorry for reply so late

Does the problem persist?

[crimsonstone]

Has anyone tried this in 0.8.7a, yet?

[Hitch]

I've been using it on 8.7a since the first week of december with no problems. Currently watching 23 cisco cmts units.

[crimsonstone]

Groovy. I'll give it a shot.

[Nevare]

Is there a way to quickly graph the uBRs interfaces with the correct templates?

I run six uBR10012s with a _lot_ of interfaces...

[Spark]

Hi, Im using in:
uBR 7223
uBR 7246
uBR 10K

Example: Success [908 Items, 227 Rows]

I can export all the templates from the cacti Version 0.8.7a
Using Spine

if anyone needed

Thanks

Howdy,

I am trying to get this to go on my UBR 10k, however, it is not graphing SNR as I would like it to be.

See the attachment:

How do I get it to display the actual SNR....right now it seems to be dividing the number by 10.

Actually, the uBR10k gives SNR values measured in tenth of a dB (atleast via SNMP), try checking what kind of response you get from manually running an snmpget/walk. I use the "Divide by 10" CDEF in order to represent my graphs in dB, so unless you've accidentially added it again somewhere, you must have a funny OS version running on your CMTS.

[jbarbieri]

I normally do have to divide by 10, thats what I do for MRTG.

I was just wondering if this is dividing by 10 twice, or if its polling a different OID, or if its just graphing differently.

And I am running 12.3 (21a) BC6

Which came out a couple months ago.

My SNR graphs look fine, and I haven't changed the template. I'm running 12.3 21a BC1. Did you do a manual snmpget? You might want to check the debug of your graph (preferably, paste the debug info here so that we can see what happens to the data).

I hate to really bring this back up, but I am starting to really use Cacti a lot more, and the SNR is still showing incorrectly.

Does anybody see something different in my debugs?


Edit-------------------
I shut off the "diviser par dix" in the graph template, and my graphs now are working right.

"Diviser par dix" literally means "divide by ten" in french, was this enabled twice?

No, it was not.

And I did know that meant divide by ten, but it was not enabled twice.

Maybe this is monitoring a different OID that I usually monitor, where I do have to divide by 10.
