Yeah, as Bob said, cron-trigger is what you are looking for.

As our discussion on IRC, currently, Mistral doesn't support to execute
shell command directly, my suggestion is, you could consider using http
action (which is supproted by Mistral out of the box) or providing a host
(physical or virtual) to run 'ping' command and use ssh action in Mistral.
