-alias

-logger

The alias for the logger session.

-schedule

The schedule to follow when monitoring. It defaults to: "*/1 * * * *". Which is do something once a minute.

initialize

This method declares the event "monitor" and opens the connection to the database.

cleanup

This method stops the "monitor" processing and closes the database connection.

PUBLIC EVENTS

startup

This event schedules the processing of "monitor" with the supplied schedule.

shutdown

This is triggered by a "shutdown" event and calls the cleanup() method.

This event does the actual monitoring. By default it does nothing and needs to be overridden. It takes two parameters: $kernel, $self.
