SNMP timeout on Cacti 0.8.8g

[JulienWCNT]

Hi, I need some help for a timeout problem concerning some SNMP requests. I created templates to graph frequency on antennas, but the grah remains empty, and when I look in the logs, it's always written:
WARNING: SNMP Get Timeout for Host:'172.18.224.144', and OID:'.1.3.6.1.4.1.3942.1.1.2.1.1.3'
But when I do the following request on the server:
snmpwalk -c "name of the community -v2c 172.18.224.144 .1.3.6.1.4.1.3942.1.1.2.1.1.3
I always get the answer I want: SNMPv2-SMI::enterprises.3942.1.1.2.1.1.3.3 = INTEGER: 5470000
I reduced the number of max OID in a request and augmentated the timeout, but it doesn't change anything, I still get the same answer, and I'm running out of ideas. I hope somebody have an answer to my problem. Thank you, and have a nice day.

Edit: I also sometime have this in the logs:
SNMP: v2: 172.18.224.144, dsname: rmFrequency, oid: .1.3.6.1.4.1.3942.1.1.2.1.1.3, output: U
I don't know if it just mean that the request didn't worked, or if it's something else.

can you post your setup in Cacti for this ?

snmpwalk and snmpget aren't the same. The error reffers to the SNMPGet timeout, while you're doing an SNMP Walk. Also the OIDs differ from the error message and the OID which is in your snmpwalk:

Code: Select all

.1.3.6.1.4.1.3942.1.1.2.1.1.3  ( Snmpget )
vs.
.1.3.6.1.4.1.3942.1.1.2.1.1.3.3 ( Snmpwalk )

Thanks for your answer, first you are right, if I wan't to have the answer with "snmpget", I need to use the .1.3.6.1.4.1.3942.1.1.2.1.1.3.3, and not .1.3.6.1.4.1.3942.1.1.2.1.1.3
I don't know why, but I see the second value with iReasoning.
Now I have this in the log:
SNMP: v2: 172.18.224.144, dsname: rmFrequency, oid: .1.3.6.1.4.1.3942.1.1.2.1.1.3.3, output: 5470000
So it seems to work, but the grah remains empty, do you have any idea of what could provent it from working?

Edit: A mistake in the interpretation of "Last" for the graph value was creating this problem, thanks for the hepl!
