Nagios passive check not changing alert condition

[Marc Powell]

Just some suggestions --

Enable logging of passive checks in nagios.cfg -
log_passive_service_checks=1 
Make sure that you're accepting passive checks in nagios.cfg -
accept_passive_service_checks=1 

Check nagios.log and make sure that nagios is seeing and properly
processing the passive service check. 

In the submit_check_result below, the host ($1) and service description
($2) must exactly match what nagios has in it's configs. For the
example you provide, you should be submitting something (after
substitution) like:   

cmdline="[$datetime] PROCESS_SERVICE_CHECK_RESULT;$1;$2;$3;$4"

cmdline="[timestamp]
PROCESS_SERVICE_CHECK_RESULT;TestRouter;SNMP-TRAP;1;Plugin Output"
-(example for a WARNING)
