No Such Instance currently exists at this OID

Hi,

I try it, but i have some errors. I'm trying to query data from my fortigate.
I get these errors:

/opt/splunk/etc/apps/snmp_ta/bin/snmp.py" Traceback (most recent call last):
/opt/splunk/etc/apps/snmp_ta/bin/snmp.py"   File "/opt/splunk/etc/apps/snmp_ta/bin/snmp.py", line 492, in <module>

/opt/splunk/etc/apps/snmp_ta/bin/snmp.py" UnboundLocalError: local variable 'oid_args' referenced before assignment

In my splunk index:

FORTINET-FORTIGATE-MIB::fgSysCpuUsage."" = "No Such Instance currently exists at this OID" 
FORTINET-CORE-MIB::fnSysSerial."" = "No Such Instance currently exists at this OID"

With MibViewer I have received the snmp reply:

Send snmp get request to x.x.x.x:161
.1.3.6.1.4.1.12356.100.1.1.1.0 (not in loaded mib files) --> FG600C3912801998

Send snmp get request to x.x.x.x1:161
.1.3.6.1.4.1.12356.101.4.1.3.0 (not in loaded mib files) --> 0

You get the "No Such Instance currently exists at this OID" message if you make an SNMP request for a non-existent OID, or for an OID that has multiple instances without including an appropriate leaf instance identifier.

What does your SNMP configuration in Splunk look like (in the inputs.conf file) ?

I did try with Object Names too, but the result is wronger: no data @ my index. The result is the same with mibviewer.

pffff... I have found the problem.

Wrong Settings:
object_names = 1.3.6.1.4.1.12356.101.4.1.3
object_names = 1.3.6.1.4.1.12356.101.4.1.3

Good Settings:
object_names = 1.3.6.1.4.1.12356.101.4.1.3.0
object_names = 1.3.6.1.4.1.12356.101.4.1.3.0

You need to add an ".0" string to end of your query and all it is OK.

Yes , unless you tell the SNMP Mod Input to do a bulk get (where it will walk the OID tree) , you need to provide the fully qualified OID name (all the way to the leaf).
