[Nagiosplug-devel] check_snmp bug report and feature request: negative numbers for warning and critical flags

[Michael J. Bauer]

The check_snmp documentation says that both the warning and critical 
flags take integer ranges as arguments.  However, both flags fail on 
negative integer ranges:

# ./check_snmp -H localhost -o .1.3.6.1.4.1.42.2.70.101.1.1.8.1.4.88 -C 
public --critical=-13007:-11036
check_snmp: Invalid critical threshold - -13007:-11036
Usage:check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range]
[-C community] [-s string] [-r regex] [-R regexi] [-t timeout] [-e retries]
[-l label] [-u units] [-p port-number] [-d delimiter] [-D output-delimiter]
[-m miblist] [-P snmp version] [-L seclevel] [-U secname] [-a authproto]
[-A authpasswd] [-X privpasswd]

I get the same result if I change it to --warning, or if I use -c or -w 
without the =.  The OID in question is a sensor for the -12V power on a 
SunFire X4100 M2 motherboard.  It reports voltage * 1000, and I'd like 
to be able to monitor it.

The OS and version I'm using.  The hardware is a SunFire X4100 M2 in all 
cases.  As far as I can tell, I have the latest version of check_snmp, 
but I know that Red Hat versioning can be slippery.
