# Can be used with monit configuration: | |
# check program testone with path "/etc/monit.d/libexec/pidfile-checker.sh -p /tmp/testone.pid /tmp/server.sh" | |
# if status != 0 then exec "/bin/rm -f /tmp/testone.pid" | |
# | |
# You can add "as uid <username> group <groupname>" to the end of the exec statement if you like (I do). | |
# You probably want to set a sensible alert message. | |
# | |
# Note that 'with path "command args"' was only supported in some version of monit > 5.5.1 and <= 5.8.1 | |
# before that mysterious release, you could only use commands without arguments. |
