Hello. I would like to use check_http to check a webpage for a certain word to see if it's working correctly. If I run check_http from the command line, it works fine: [root@nagios ~]# check_http -H uranus -u "<a href="http://uranus/cognos8/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/main.xts&startwel=yes">http://uranus/cognos8/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/main.xts&startwel=yes</a>" -f follow --string=Query HTTP OK: HTTP/1.1 200 OK - 2059 bytes in 0.149 second response time |time=0.148962s;;;0.000000 size=2059B;;;0 I know that it's checking the page correctly because if I query for a word that isn't on that page I get an error: [root@nagios ~]# check_http -H uranus -u "<a href="http://uranus/cognos8/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/main.xts&startwel=yes">http://uranus/cognos8/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/main.xts&startwel=yes</a>" -f follow --string=blah HTTP CRITICAL: HTTP/1.1 200 OK - string not found - 2059 bytes in 0.148 second response time |time=0.148124s;;;0.000000 size=2059B;;;0 I have my configuration file for this website configured like this: define service{ use generic-service ; Inherit default values from a template host_name uranus service_description Check page content for the word password check_command check_http! -H uranus -u "<a href="http://uranus/cognos8/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/main.xts&startwel=yes">http://uranus/cognos8/cgi-bin/cognos.cgi?b_action=xts.run&m=portal/main.xts&startwel=yes</a>" -f follow --string=Query } I force a check in Nagios and see this in the Nagios logs: [1259172769] EXTERNAL COMMAND: SCHEDULE_FORCED_HOST_SVC_CHECKS;uranus;1259172769 [1259172774] SERVICE ALERT: uranus;Check page content for the word password;CRITICAL;SOFT;1;HTTP CRITICAL: HTTP/1.1 404 Not Found - string not found - 478 bytes in 0.003 second response time I see that it's getting a 404 error. Is it not handling the URL the same way in the config file as it does from the command line? What can I do to fix this? Thank you..
