Re: Knowing if application is "alive"

Have the running apps log an event, then remotely read the event logs and
scan for the messages. If you dont see them its not running(or at least
properly). If they have write they can even log the messages to the machine
your monitoring and to a specific log(instead of the standard logs). this
way you dont have to read through huge files.

You can also use SMNP traps as well.
