Re: Monit http error status

[Martin Pala]

Hi,

the default HTTP protocol test returns just failure if the HTTP code is error.

You can use the "check program" test with custom script and use curl/wget to 
get the http response code, for example (not tested):
/usr/local/bin/myhttptest.sh:
--8<--
#!/bin/bash
exit `curl -sL -w "%{http_code}\\n" "http://mymachine"; -o /dev/null`
--8<--

and then connect it to Monit like this:
--8<--
check process apache with pidfile /var/run/apache.pid
    start program = ...
    stop program = ...

check program myhttptest with path /usr/local/bin/myhttptest.sh
    if status == 502 then restart
    depends on apache
--8<--



Another option is to use the generic send/expect test to write simple HTTP 
check and test the 502 response - generic example from the monit manual:
--8<--
 if failed host cave.persia.ir port 4040
    send "Open, Sesame!\r\n"
    expect "Please enter the cave\r\n"
    send "Shut, Sesame!\r\n"
    expect "See you later [A-Za-z ]+\r\n"
 then restart
--8<--


Regards,
Martin
