OID for processor usage changes after a restart

[jagbarcelo]

This is a simple one, but I cannot find a single word in cacti documentation about this subject.

OID for processor usage is .1.3.6.1.2.1.25.3.3.1.2.X where X is the id of the processor.

For whatever the reason (I don't know), this X is not fixed for my servers (I don't know if this happens to everyone). This number changes sometimes after a restart and the processor usage informatinon stops being monitored.

If I define the whole OID for the processor, i.e. .1.3.6.1.2.1.25.3.3.1.2.1 (note the last 1), it runs fine for some time, but after a restart of the server this 1 might have changed to another number, 5 for instance. When I note the graph is not showing correctly, I have to go and find the new value that should be used in the OID field of the datasource, and change it accordingly (to .1.3.6.1.2.1.25.3.3.1.2.5 in this case). This manual fix is not a nice/elegant solution to the problem.

I thought there would be a feature such as not defining this OID completely and leave it as .1.3.6.1.2.1.25.3.3.1.2.X so that cacti (or cactid) do a walk of that branch and retrieve the correct value (whatever X is). So I tried to define the OID of my datasource to .1.3.6.1.2.1.25.3.3.1.2.X and recieve the following error message in cacti.log:

Is there any documentation about defining multi snmp oids? Will multi snmp oids solve my problem or should I use other feature?

Regards.

Can you please test with the attached version of Cactid and provide feedback. There was a corner case problem in the prior version that was causing issues if the number of OID's to retrieve was larger than the MAX OID GET size and the first round of OID's has "U" results.

I'm now using the version of cactid you have just uploaded. I have also set poller looging level to DEBUG. Here are the results:

Data set 64 is defined for host 10.0.3.2 and OID .1.3.6.1.2.1.25.3.3.1.2.X
Still the same behaviour. Should I define OID to a different value? What kind of feedback do u need?

Thanks and regards.

'.X' can never be valid. Should always be numeric.
