DOCSIS Stats

[BSOD2600]

I might play around with it over spring break with my parents cable modem on Comcast (they block snmp).

[Mees]

Thans for the this "Coocking book" in how to set up polling via the script server.
I am have been implementing this on one of my modems also, which now is easy

One thing I have seen is that when I run two different templates from the same script, it seems like (poller cache and log file) that the script is runned twice during one 5 min. cycle.
Does cacti and its script server understand that it only needs to run this script once, or will it run the script twice on the same host when the two graph templates utilised ?

So does Cacti, like MRTG, economise on the polling?

Best regards,
Mees

[BSOD2600]

The script should only be run once per data source its set on...

[oscar.sanabria]

My CM's support SNMP but when the cacti create graphs for signal levels and Stat Counters, thats not take datas, the graph dont have data, is empty, without data.

Any can help me...My grpahs are same that jadam's graph,

This is a example in debug mode in data source:

doesn't look like your modem supports all the fields that are being queried.

snmpwalk .1.3.6.1.2.1.10.127.1.1.1.1.6 and post the results.

Also manually run the script under the php script server and see what the results are.

[oscar.sanabria]

Hi.

This are my result for u mib:

SNMPv2-SMI::transmission.127.1.1.1.1.6.3 = INTEGER: 0

Thanks a lot.

[BSOD2600]

hmm, ok. So what happens when you manually run the script under the script server?

[kanada]

Hmm.. i have one problem when i load this script. Cacti in debug mode tell me:

ERROR: Not enough arguments

I clean load this script, so i don't understand.

Bay the way, when i made from console:
php scripts/ss_docsis_stats.php 10.80.4.7 public 2 161 500

i get answer:

docsIfDownChannelPower:141 docsIfSigQSignalNoise:378 docsIfSigQMicroreflections:36 docsIfCmRangingTimeout:5 docsIfCmStatusTxPower:393 docsIfCmStatusResets:0 docsIfCmStatusLostSyncs:0 docsIfCmStatusT1Timeouts:0 docsIfCmStatusT2Timeouts:0 docsIfCmStatusT3Timeouts:0 docsIfCmStatusT4

& rrd begin make graphs, but without results.

any ideas? Thanks..

Greetz,

Alexander.

[BSOD2600]

Are you using cmd.php or cactid poller?

Clear your poller cache. Post the section of cacti log where the script runs.

[kanada]

Are you using cmd.php or cactid poller?

Clear your poller cache. Post the section of cacti log where the script runs.

I test it on cmd/cactid poller, on both rrd made graphs without results.

Older problem was solved (in script was no spaces between parameters, maybe someone will be repair that?)

Now all its ok.

Many Thanks && Greetz,

Alexander

[BSOD2600]

Space between the parameters in the Data Input Method? Sounds like it wasn't properly imported or something.... the default script has spaces.

[quinten]

also be sure you have these mibs in your snmp/mibs directory.

docs-baseline-privacy.mib
docs-cable-device.mib
docs-cable-if.mib

without these mibs, some docsis devices will not report the correct information OID, or it will say that the OID is not supported on X device.

The scripts use the DOCSIS standard v2 SNMP MIB, which is globally uniform for ALL docsis devices... if the modem does not answer the above mibs, its not fully DOCSIS compliant and should be beaten, burned, shot, blown up and trashed.

I have yet to find a Docsis Device that does not answer any of the above mib's.

[3AHO3A]

Hi. Have a problem. Docsis signal & stats dont appear. Modem is answering my SNMP queries, cause i can see the modem traffic information. Please show me where to dig?
thanx in advance

i think this is the problem logs

Please manually run the script under the script server and see what it reports back. It's possible your modem doesn't report all the snmp data.
