trouble w/SNMP

[Natalie Aloi]

Thanks Allan! That's what its doing a getnext - see below!
note mib oid and value!

[root at nagios mibwalk]# snmpgetnext -v 1 -c public 10.1.102.40 SNMPv2-SMI::mib-2.33.1.1.5.0
SNMPv2-SMI::mib-2.33.1.2.1.0 = INTEGER: 1
[root at nagios mibwalk]#

hmmm now I need to figure out how to tell nagios to do a walk on that oid...

I am trying to get something to work in Nagios and my command generates a response of unknown, but the snmpwalk generates a value of 2
I also tried another oid and the values generated are identical for the snmpwalk and the snmpget

(the one for the upsBatteryStatus is the one I am curious about)


[root at nagios mibwalk]# /usr/lib/nagios/plugins/check_snmp -H 10.1.102.40 -C public -o SNMPv2-SMI::mib-2.33.1.2.2.0
SNMP OK - 0 seconds | UPS-MIB::upsSecondsOnBattery.0=0 seconds

[root at nagios mibwalk]# /usr/lib/nagios/plugins/check_snmp -H 10.1.102.40 -C public -o SNMPv2-SMI::mib-2.33.1.2.1.0
SNMP OK - unknown(1) | UPS-MIB::upsBatteryStatus.0=unknown(1)
[root at nagios mibwalk]#

Data from snmpwalk is below:


UPS-MIB::upsBatteryStatus.0 = INTEGER: batteryNormal(2)
UPS-MIB::upsSecondsOnBattery.0 = INTEGER: 0 seconds





try something like:

 snmpget -v 1 -c public 10.1.102.40 SNMPv2-SMI::mib-2.33.1.2.1.0

Assuming SNMP-v1; try with "-v 2c" as well, to see which one matches your results. I don't have a commandline available to check which the snmp command plugin uses, but maybe this will give you an idea whether the snmpwalk differs form the snmpget result, perhaps an avenue to investigate further.

If we assume Nagios is doing snmpget rather than snmpwalk, then the problem is slightly different: how would we get snmpget to produce the desired/accurate "2" rather than "1".

For giggles, try:

snmpget -v 1 -c public 10.1.102.40 SNMPv2-SMI::mib-2.33.1.2.1

(dropping the .0)

I'm curious about this because I remember something with snmpwalk needing a .0 in places where snmpget didn't seem to. Don't recall exactly what it was.
