I'm having trouble calling check_snmp with multiple OIDs. Tested with 1.14.16 and 2.0.3.
It works with some OIDs, but not others.

combo of syName & sysDescr works fine.

check_snmp -P 2c -H XXXX -C XXXX -o .1.3.6.1.2.1.1.5.0 -o .1.3.6.1.2.1.1.1.0 -l sysName -l sysDescr
SNMP OK - sysName "xBalancer1" sysDescr "xBalancer" |

Then there's these two OIDs, IF-MIB::ifOutOctets, and IF-MIB::ifInOctets, which work on their own.

check_snmp -P 2c -H XXXX -C XXXX -o .1.3.6.1.2.1.2.2.1.16.1
SNMP OK - 3234859200 | iso.3.6.1.2.1.2.2.1.16.1=3234859200c
check_snmp -P 2c -H XXXX -C XXXX -o .1.3.6.1.2.1.2.2.1.10.1
SNMP OK - 15737717 | iso.3.6.1.2.1.2.2.1.10.1=15737717c

But when I try to get those same two OIDs in one call, it fails.

check_snmp -P 2c -H XXXX -C XXXX -o .1.3.6.1.2.1.2.2.1.16.1 -o .1.3.6.1.2.1.2.2.1.10.1
External command error: Error in packet

Failed object: iso.3.6.1.2.1.2.2.1.10.1

Odd. Using 2.0.3, I can check multiple oids: Can you try running the check in verbose mode and post the output?

Must be something broken in the SNMP implementation of the device type I'm trying to poll then.
Thanks for the sanity check.

Fair enough, though verbose mode (-vvv) may shed some light on the "why?".

check_snmp with multiple OIDs. Is simple only is executed as follows



./check_snmp -H 1x.x.x.x -C name -o .1.3.6.1.4.1.13045.1.1.2.2.1.4.3,.1.3.6.1.4.1.13045.1.1.2.2.1.4.1 -w 24,40 -c 40,42 -l "Temperature,Humidity"

OUTPUT:
Temperature CRITICAL - Temperature 22 Humidity *43* | Temperature=22;0:24;0:40 Humidity=43;0:40;0:42

Yeah, though I think OP's problem is related to an snmp device with an odd snmp implementation.

You can test if the device returns data using snmpwalk.

Temperature
# snmpwalk -c name x.x.x.x -On .1.3.6.1.4.1.13045.1.1.2.2.1.4.3 -v1
.1.3.6.1.4.1.13045.1.1.2.2.1.4.3 = INTEGER: 22

Humidity
# snmpwalk -c name x.x.x.x -On .1.3.6.1.4.1.13045.1.1.2.2.1.4.1 -v1
.1.3.6.1.4.1.13045.1.1.2.2.1.4.1 = INTEGER: 45

The above command return data(INTEGER: 22, INTEGER: 45), we can say that the device returns information using snmp agent

OP: Do you need any more help, or should we lock this thread?
