VoIP Sessions graph

imran.alvi · Post by **imran.alvi** » Thu Oct 09, 2008 2:06 am

cacti is the best tool around for NMS. It made my life easier. Now I am trying to make the graphs for my VoIP proxy servers which are Acme Packet Net-Net model. I used the Generic OID template for fetching the SNMP stats for total VoIP sessions on the VoIP proxy Server but didnt get through. The OID I am using is working Ok in MRTG and i have build the graph but somehow I am missing something or doing something wrong here. Kindly help me out here. the logs show me the value "U" against the OID but as I a mentioned earlier the same OID is working fine in MRTG.

HELP ...

Please post result of an snmpwalk against that OID and the exact error message in the cacti.log file

I issued the command mentioned below
snmpwalk -v 2c -On -c acmepacket 10.1.6.41 1.3.6.1.4.1.9148.3.2.1
Output is attached.

Cacti Log: 10/10/2008 12:15:03 PM - SPINE: Poller[0] Host[448] DS[197521] SNMP: v2: 10.1.6.31, dsname: snmp_oid, oid: .1.3.6.1.4.1.9148.3.2.1.2.4.1.7.3 = Counter32: 2947

This integer value is changing constantly. Now I can see thee graph but no output shown. Attached is the graph PNG.

Please debug as given in 2nd link of my sig. Serach for the "rrdtool update" one and verify it. I assume, that the data source MAX issue has hit you

thanks for the help, i will test it, one thing more rrdtool update will not effect current ok graphs right?

And please send me the link you mentioned in your last reply i was not able to find it.

Ok thanks, i'll do that, if I try the "rrdtool update" to create rrd data files will it effect the exsisting rrd data files currently being maintained for my other critical devices in cacti?

Becuase I have a single node of cacti monitoring the whole network including our Cisco GSR routers. And i dont want to take risk, if its risky I will install another node of cacti for new rrd data files to accomodate data source MAX issue.

I have found a very useful doc regarding the rrdtool. Attached is the pdf.

Existing rrd files will not be affected. But it is always a good idea to debug using a test installation
