Hi to all,
I have strange issue when i'm using check_snmp plugin with -u option.
Nagios Core 4.1.1
Nagios plugin 2.1.1
Ubuntu 14
Command : check_snmp!-C public -o BSS-RCP-MIB::storage-load.0 -u % -c 1:100
Nagios service :
Status Information: SNMP OK - 12 %
Performance Data: BSS-RCP-MIB::storage-load.0=12;;1:100%;;100;
No RRD file created, error in perfdata format % is after the critical threshold and not after the value.
Command : check_snmp!-C public -o BSS-RCP-MIB::storage-load.0 -c 1:100
Nagios service :
Status Information: SNMP OK - 1
Performance Data: BSS-RCP-MIB::storage-load.0=1;;1:100;;100;
RRD file created, correct perfdata output
Does someone already seen this? or better does someone have a solution.
Best regards
Sebastien

Can you run the check_snmp command over the CLI, and post the full command and output for us to look at?
As well, what happens if you place the % in quotes?
Code: Select all
check_snmp!-C public -o BSS-RCP-MIB::storage-load.0 -u "%" -c 1:100

Hi rkennedy,
I just do the test and unfortunately I have the same result
Code: Select all
check_snmp!-C public -o BSS-RCP-MIB::cpu-load-idle.1 -u "%" -w 8:100 -c 2:100
Perfdata output with error with "%" at the wrong place
BSS-RCP-MIB::cpu-load-idle.1=87;8:100;2:100%;100;100;
It looks like a bug

Can you execute these commands and post back the output:
Code: Select all
./check_snmp -H xxx.xxx.xxx.xxx -C public -o BSS-RCP-MIB::storage-load.0 -u % -v
Code: Select all
./check_snmp -H xxx.xxx.xxx.xxx -C public -o BSS-RCP-MIB::storage-load.0 -u % -c 1:100 -v
Code: Select all
/usr/bin/snmpget -Le -t 1 -r 5 -m ALL -v 1 -c public xxx.xxx.xxx.xxx:161 BSS-RCP-MIB::storage-load.0 -D all
Replace xxx.xxx.xxx.xxx with the correct IP.

I verified that using the -u "units" option for check_snmp version 2.1.1 outputs the unit in the wrong location in the performance data.
Running the same check command using version 2.0.3 puts the unit in the correct location.
I will fill on a bug report for this.

Nice troubleshooting
@tgriep.
@Seb06 as a temporary workaround you could compile plugins 2.0.3 and just copy the check_snmp binary over the 2.1.1 version to work around your issue.
