Snmpwalk not supported

#1 Post by click » Thu May 27, 2010 6:01 am

Hello,
I'm trying to graph an ADC device with built in support for snmpget command (snmp v1) but not for snmpwalk. Is there a way to create graphs for this device in Cacti? I have tried to use "SNMP - Generic OID Template" for single OID, but the graph dont show up. When I turn on the graph debug mode there is a rrdtool error: "ERROR: opening '/var/lib/cacti/rra/test_pico_snmp_oid_272.rrd': No such file or directory
". Snmpget for the same OID is OK. Cacti version is 0.8.7b.
Any help is appreciated!

Does this error occur only on this OID/Device or on different ones too?
What polling mechanism do you use?
Does your cacti log tell you a story (log level = debug)
Try to snmpwalk the oid/device (snmpwalk -v [version] -c [vstring] [ip/hostname] [oid])
Is the host in the devices tab shown as Up?

Code: Select all

"ERROR: opening '/var/lib/cacti/rra/test_pico_snmp_oid_272.rrd': No such file or directory"
This error means there is no .rrd file. Check the permission from the rra/ dir and the owner status of the .rrd files.

This error occurs only on this device.
Im using Spine.
The host is up when I use ping+snmp for detection. Using snmp only shows it as down.
In debug log there is nothing about this device.
I cant snmpwalk because the device do not support this command. It supports only snmpget. Snmpget works just fine from console.

Permissions are OK. This cacti box graphs many devices (mainly switches) and I dont have any issues with them.

Mhm Sorry, my mistake.

Don't know if this helps, but you can try.

Goto Console/Configuration/Settings/Poller
->Spine Specific Execution Parameters
->The Maximum SNMP OID's Per SNMP Get Request

Set this one to 0 or 1.
