snmp - nagios wont detect service status change


I am monitoring an APC UPS' Basic Output Status (on-line / off-line - using battery)

Here is a copy of my command:
snmp_ups_stat $USER1$/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -o .1.3.6.1.4.1.318.1.1.1.4.1.1.0 -w 3 -c 4 -l 'UPS Status'

I can unplug the UPS and the status will change from 2 (on-line) to 3 (off-line):
iso.3.6.1.4.1.318.1.1.1.4.1.1.0=3 (from Nagios' service detail webpage)

but the status remains OK:
Current Status: OK (for 0d 17h 4m 48s)
Status Information: UPS Status OK - 3
Performance Data: iso.3.6.1.4.1.318.1.1.1.4.1.1.0=3

Am I doing something wrong here?

I'm having a very similar problem.

I use a service with the following command:

check_device!-H 217.x.x.x-C nxxxxxca -o ifOperStatus.xxxx

Everything appears to work fine. Both from within Nagios and from the Bash shell. However, when I temporarily force the line down, there is no change as illustrated in the following images:

Am I making a obvious error? I use Centreon to configure Nagios but I doubt this has any effect on the actual functionality.

Thanks in advance!

I figured it out!

I hope this helps you, too.
In my listing of different status types for the UPS, it begins with the number 1: 1=unknown, 2=online, 3=offline, etc. With SNMP, it begins with the number 0 (there is an offset by -1). So SNMP sees it as 0=unknown, 1=online, 2=offline, etc.
