06/09/2008 01:52:27 PM - CACTID: Poller[0] Host[1048] DS[14387] SNMP: v2: (.. not important ..), dsname: snmp_oid, oid: .1.3.6.1.4.1.2021.8.1.100, value: U
06/09/2008 01:52:27 PM - CACTID: Poller[0] Host[1048] DS[14392] SNMP: v2: (.. not important ..), dsname: mem_cache, oid: .1.3.6.1.4.1.2021.4.15.0, value: 370424

Code: Select all

[root ]# snmpwalk (.. not important ..) .1.3.6.1.4.1.2021.8.1.100
UCD-SNMP-MIB::extResult.1 = INTEGER: 72
[root ]# snmpwalk (.. not important ..) .1.3.6.1.4.1.2021.4.15.0
UCD-SNMP-MIB::memCached.0 = INTEGER: 370448

so - snmp polilng a host works like a charm, the values are returned, the oid is correct, but cacti said - U (nknown value) - why? what to check?

Are the not important parts from the log exactly the same as the ones from the test commands ?
Have the test commands have been executed on the very same host cacti's poller is running on ?

Maybe you could try using snmp V1 ? There has been some threads here about V2, if i remember correctly.

dus do you mind posting constructive replies? im using cacti for a long time and 'm really able to solve problems myself - but i've just stumbled on something strange, and working against any logical explanation...

once more - Reinhard?

Please do not snmpwalk against .1.3.6.1.4.1.2021.8.1.100 but snmpget against .1.3.6.1.4.1.2021.8.1.100.1

Guys! i'm beggining to think, you're not reading and understanding what my problem is! i'm running proper snmp queries, from the same host, to the same host, with the same credentials. it's not a matter of snmpwalk/snmpget - as a matter of fact, for a single oid, they work the same.

the problem is:

why the fsck can i poll both variables by hand, and cacti can poll one, and cannot the other??

I have to re-phrase: Please make cacti NOT poll .1.3.6.1.4.1.2021.8.1.100 but make it poll .1.3.6.1.4.1.2021.8.1.100.1
Your example from above shows, that the target is responding to .1.3.6.1.4.1.2021.8.1.100.1 and NOT to .1.3.6.1.4.1.2021.8.1.100
