Strange thing with snmp poller.

[Vitriol]

I have a problem with polling some OID of my localhost snmpd. This OID is generated by a script. There are 4 actually the same OIDs, but three of them are generated normally and one not.
There is cacti log:

Code: Select all

when i poll this through snmpwalk utility i see no problems:

What does this "output: U" mean?

[TheWitness]

It means that Cacti could not interpret the result, or there was some timeout that prevented the correct result from returning in time. Typically, when that happens, you get another message in your log though.

How can I find what timeout I have? Can it be tuned up?
