The next monit version will allow to customize the service non-existence
condition. Changelog excerpt:
--8<--
* Allow to override default action when service doesn't exist (for example
process
is not running, file doesn't exist). Default action is service restart, it
can be
customized with following statement now:
if [does] not exist [[<x> times within] <y> cycles] then <action1>
[else if succeeded [[<x> times within] <y> cycles] then <action2>]
For example instead of default restart action:
check file with path /cifs/mydata
if does not exist for 5 cycles then exec "/usr/bin/mount_cifs.sh"
