Apcupsd Notification and Events
When a major event is generated within apcupsd, control is passed to the
script apccontrol normally found in /etc/apcupsd/apccontrol. The event
name, and a number of other important parameters are passed to the script.
The major function of the apccontrol script is to performa a shutdown of
the system (as well as the killpower operation). In addition, another major
task for this script is to notify you by email when certain events such as
powerfail occur.
Since apccontrol is a script, you can customize it to your own needs using
any text editor. To do so, you must have a minimal knowledge of Unix
shell programming. In addition, another feature is that you can write your
own scripts that will be automatically called by apccontrol before any of
its own code is executed. Details of the events and how to program them
are contained in the Advanced topics section entitled Customizing Event
Handling (see Customizing Event Handling).
