[Help] Can anyone help me to create these two templates ?

[dust2k]

I am currently monitoring ADSL SNR and Attenuation for my Billion 7402VGO ADSL modem/router by using following section in MRTG with RFC1471-MIB,RFC1472-MIB,RFC1473-MIB,RFC1474-MIB,RFC1695-MIB,RFC2493-MIB,RFC2662-MIB loaded, by converting all graphs into cacti I need create template to generate SNR and attenuation in cacti, but I don't have any idea how to create them, can anyone help me on this ? thanks

Sorry for knowing nothing about MRTG. But help is available if you are able to specify the OIDs needed. They may be "simple" OIDs or part of a TABLE. cacti does not rely on MIBs, so the named OIDs do not help. Please provide numeric OIDs. Some snmpwalk against those OIDs would help a lot.

Search on google about "rfc2662" which have the variables from MRTG cfg file, I found this 3155.1453.6555.26760 as OID, not sure this does help you or not.

I use Getif to search on the ADSL modem and found .iso.3.6.1.4.1.17453.0 is sysObjectID.

that is very difficult to make templates without oids 、oid types and structure, also target machine is nessary to check your newly created template works fine or not, graph and data template included.

[dust2k]

so what's the best way to find out OIDs and structure of them ?

If you have a running MRTG system, please tcpdump a couple of requests against your target system. In this trace, you will find all necessary OIDs

Ooops, this is the first time to use TCPDump, I downloaded microldap's windows tcpdump, but I am not sure which command line just can capture certain dst IP (192,168.1.254) with port 161 and all SNMP packages, can you give me some hints ?

When running a windows system, I'd definitively have a look at ethereal at http://www.ethereal.com/. Don't forget the winpcap. When starting the trace, it will ask you for a filter option. Use the string port 161.

Just try to make things simple, what's command line options to catpure all packages point to 192.168.1.254:161 ?

I have managed to get data on these sort of figures out of my Billion 7402 VGP to graph in Cacti using the named OIDs - the problem is there don't seem to be any dB-related graph templates, and I'm new to Cacti, so I'm not really sure how to create them.

Code: Select all

tcpdump host 192.168.1.254 port 161

if you're using a special interface (e.g. bond0) you'll have to prepend -i bond0

There is only one network interface card so don't need point the interface, but your command gives parse error, I will try to read manual to get it right bit lazy yesterday.

Finally done the capture with ethereal, the file is here, the capture filter is "host 192.168.1.254 and port 161" . I am currently monitor four interfaces (ppp-1, wireless bridge and ethernet) plus uptime, SNR and ATT.

The order from MRTG .cfg file is Ethernet interface , bridge, wireless, Uptime, SNR, Attenuation , ADSL. I believe the captured package are following the same order, so second last and third last will be the OIDs I need for querying the device.

thanks lvm.

[gandalf]

So you're right on the track now, eh? If not, please post the OIDs...

[dust2k]

Oooops, I thought u use ethereal to check on OIDs already, hehe, OK, Here they are :

SNR : OID1 :1.3.6.1.2.1.10.94.1.1.2.1.4.4
OID2 : 1.3.6.1.2.1.10.94.1.1.3.1.4.4

Attenuation : OID1 :1.3.6.1.2.1.10.94.1.1.2.1.5.4
OID2 : 1.3.6.1.2.1.10.94.1.1.3.1.5.4
