I had a similar thing working on an older version and when I upgraded I had to track that down.

using Nagios version 1.3 with Plugins version 1.4-2 on a debian sarge system.<o:p></o:p> I am using perfparse to capture performance data to mysql.<o:p></o:p> I am trying to capture an rfinput value of a wireless device through the check_snmp plugin and write it to a mysql db for reporting.<o:p></o:p> <o:p> </o:p> Since check_snmp does not currently write performance data in the output I was trying to write a simple perl script to use check_snmp but add the performance data to the output.<o:p></o:p> To make a long story short my simple perl script is adding performance data to the output and perfparse is picking it up, but I noticed that the service status in Nagios is always “OK” even when the Status Information says otherwise.<o:p></o:p> <table class=MsoNormalTable border=0
