Graphing a mib with multiple values

[iamsure]

I've created an exec script that runs on a monitored machine. The machine runs the script, and happily answers snmpwalk. I formatted the script output to match cacti's defined preferences. Here is the snmpwalk:

UCD-SNMP-MIB::extIndex.1 = INTEGER: 1
UCD-SNMP-MIB::extNames.1 = STRING: cputemp.sh
UCD-SNMP-MIB::extCommand.1 = STRING: /root/bin/cputemp.sh
UCD-SNMP-MIB::extResult.1 = INTEGER: 0
UCD-SNMP-MIB::extOutput.1 = STRING: CPU1:109.40 CPU2:116.60 CPU3:105.80 CPU4:98.60 CPU5:102.20 CPU6:111.20 CPU7:111.20 CPU8:114.80
UCD-SNMP-MIB::extErrFix.1 = INTEGER: 0
UCD-SNMP-MIB::extErrFixCmd.1 = STRING:

As you can see, the output is a string with multiple (in this case, item/value pairs. (I'm attempting to monitor AMD CPU temperatures)

I've tried following the "My First Graph Template" instructions, and also the "Create a graph from a single OID" instructions, but neither worked. I don't understand the process, so I'm sure its user error.

If it helps, I'm running 0.8.7a, on FreeBSD-6.2, snmp talking via net-snmp 5.3.1.

How can I get the above into cacti, graphing, and acting like a good little first class cacti graph citizen?

Many thanks in advance.

I don't believe cacti can natively parse that, so you're going to have to write a script that will. I'd suggest using the PHP script server (ss_* script) and using cacti's built-in snmp functionality. Follow the guide(s) in the documentation site.

Its the exact format specified in the cacti documentation:

I wrote a script to change the existing output to match that, and put it into snmp.

Can anyone tell me how to set up cacti to import this data?

Correct, but cacti isn't expecting a single snmp string to contain all of that. Thats why you must spit it out with a script.
