[Freeswitch-users] CLI status?

Hi gang! I'm trying to determine the best way to periodically check the status of production Freeswitch deployments. While Freeswitch has been incredibly stable in production, I would like to ping it periodically to check that its not hung in someway. Has anyone considered or done this yet? My thought it so issue a command via fs_cli periodically and compare the out. But am trying to determine what a good command would be. thinking of using show channels or show calls, in addition to status. Any thoughts? Is this a wrong-headed approach? Thanks for any feedback.
