Check_http status 503 gives 200 OK

[Joerg Linge]

Your example

 /usr/local/nagios/libexec/check_http -I <ip address> -u http://<url> -w1 -c2

is a proxy request!

-I = ip address to connect to
-H = HTTP/1.1 Host Header
-u = relative url to fetch without protocol infos like http://

some examples

check nagios.org

OMD[gearman]:~/lib/nagios/plugins$ ./check_http -H nagios.org
HTTP OK: HTTP/1.1 200 OK - 54919 bytes in 1.703 second response time |time=1.703114s;;;0.000000 size=54919B;;;0


OMD[gearman]:~/lib/nagios/plugins$ host nagios.org
nagios.org has address 96.126.126.159

ok, nagios .org runns on 96.126.126.159
lets check a non existing page. we got 404!

OMD[gearman]:~/lib/nagios/plugins$ ./check_http -I 96.126.126.159 -H nagios.org -u /404
HTTP WARNING: HTTP/1.1 404 Not Found - 17141 bytes in 0.536 second response time |time=0.536015s;;;0.000000 size=17141B;;;0

lets ask nagios.org for icinga.org ;) and we will get a 302

OMD[gearman]:~/lib/nagios/plugins$ ./check_http -I 96.126.126.159 -H icinga.org -u /
HTTP OK: HTTP/1.1 302 Found - 242 bytes in 1.837 second response time |time=1.837209s;;;0.000000 size=242B;;;0
