Index OID's

[halfshaft]

I have written an xml in resources for cpu monitoring on one of my servers, there are plenty of OID's for differnet aspects of cpu utilization that I want to monitor but there is no Index oid.

Does 'cacti' rely on being able to walk an oid index to then walk all other oid's in the index order?

as my snmp query gives a success but 0 items and 0 rows

-------------------------------------------------------

Answered my own question!! You do need an oid_index.

Alright, sorry to resurrect an old post, but this one never got a reply and I'm vexed with the same issue - in my case, trying to graph per-port switch interface statistics where there is no ifIndex for the number of ports provided by the SNMP agent on the switch.

I read in the manual that as of Cacti 0.8.6c, one can derive the a index from a OID... but I can't find any details on how to make this happen. The manual is great about telling you that you can do things, but sparse on detail or examples. My toiling about has failed to produce anything. Running a debugged query returns 0 of 0 rows.

So, the question remains - how does one derive a index when the device's SNMP agent doesn't provide them for the things you are querying?

Any help or pointers would be GREATLY appreciated.

Please paste a walk of the entire series of the OID's within this not-indexed data query.

Thanks for the reply, TheWitness

Let me give you some quick background - This switch is a Qlogic SANbox 5200 20-port fiber channel switch, and it uses the FIBRE-CHANNEL-FE-MIB that the fiber channel working group defined some years ago.

Given that, here are the relevant bits of a snmpwalk that I want to graph on the switch. 20 ports, so I want to make a graph for each port that shows a combo of stats for a port. I've prefaced each section with the numeric OID for clarity's sake.

I do appreciate you taking the time to check this out! I'll definitely post up the configs once they get working, as this could be used against any switch that implements the FIBER-CHANNEL-FE MIB.

And attached is the Data Query XML file I'm working with from the resource/snmp_queries directory:

[TheWitness]

where is this one? .1.3.6.1.2.1.75.1.4.3.1.1

if it does not exist, then have you tried .2 for the index?

After a sanity check, I retract my post... boy do I feel silly.

By the way, thank you VERY much for doing all the hard work on generating the xml file. The thought of doing one myself was daunting to say the least.
