Yes, more or less. To have Monit send an alert message that is printed from
your script, follow this receipt
1) Add a custom mail format to the check, where the message body is just
$DESCRIPTION:
check program foo with path "/path/to/foo.sh"
alert [email protected] mail-format { message: $DESCRIPTION }
if status != 0 then alert
2) Make your script write the error message you want to send to stderr. Here is
a demo script I used to test this:
foo.sh:
#!/bin/bash
echo 1>&2 "Hello this is an error message from $0";
exit 1;
3) The alert mail you get from Monit will look something like this.
status failed (1) for /path/to/foo.sh -- Error: Hello this is an error message
from /path/to/foo.sh
The prefix 'status failed (1) for /path/to/foo.sh -- Error: ' is hardcoded in
validate.c:check_program and if it bothers you, just remove the prefix.
That is replace this line
Event_post(s, Event_Status, STATE_FAILED, status->action, "status failed
(%d) for %s -- Error: %s..", s->program->exitStatus, s->path, buf);
With this one:
Event_post(s, Event_Status, STATE_FAILED, status->action, "%s", buf);
and recompile Monit.
Hope this helps.
