Thanks for data. The settings is OK, the problem is caused by the missing
interpreter on the beginning of the script ("#!/bin/bash" for example), it
should include look like this:
--8<--
#!/bin/bash
curl https://myfavoriteapp.com --location --silent --output /dev/null
--write-out "%{http_code}\n" | grep "[2].."
exit $?
--8<--
If the interpreter is missing, monit will log the following error in verbose
mode:
--8<--
'test' failed to execute '/tmp/test.sh' -- Exec format error
--8<--
I have updated the manual - added script example and described the
requirements:
