Re: [Nagios-users] check_http and regular expressions
Here is command line definition which works fine for what you are trying to
achieve.
define command{
command_namecheck_https_reverse
command_line$USER1$/check_http -H $HOSTADDRESS$ -S -u $ARG1$ -r
$ARG2$ -r $ARG3$ --invert-regex
}

Nothing, you just don't know how nagios determines status. It's not
the plugin text output, that's just for humans. Nagios determines OK,
CRITICAL, etc from the exit code of the plugin.
All commans are run from /usr/lib/nagios/plugins directory;
/usr/lib/nagios/plugins/check_http -H x -u /sample/test.html -p
80 –a user:password -s TAPE
Response:
HTTP OK HTTP/1.1 200 OK - 0.018 second response time |
time=0.018116s;;;0.00 size=3648B;;;0
echo $? - should be 0
Now I run it with negate as you suggested:
./negate /usr/lib/nagios/plugins/check_http -H x -u /sample/
test.html -p 80 –a user:password -s TAPE
HTTP OK HTTP/1.1 200 OK - 0.006 second response time |
time=0.006001s;;;0.00 size=3648B;;;0
echo $? - should be 2
