Plesk provides a mechanism that allows administrators to track specific
Plesk events and make Plesk execute custom scripts when these events
occur. The events include operations that Plesk users perform on
accounts, subscriptions, websites, service plans, and various Plesk
settings.
It works the following way: you create a script to be executed upon a
certain Plesk event, and then set up an event handler in Server
Administration Panel that triggers processing of the event by the
script. You can assign several handlers to a single event.
To learn how to track Plesk events and set up execution of commands or
custom scripts, refer to the Administrator’s Guide, chapter Event
Tracking.
