Email Notification of Events
On Win95/98 systems, it is possible to receive notification of apcupsd events
that are passed to apccontrol. This is possible using a simple email program
that unfortunately is not functioning 100% correctly. In addition, I (Kern)
was not able to make this program work on WinNT while apcupsd is running
as a service under the system account (it works fine with any user account).
If you wish to try this program on Win95/98 systems, look at the files
named changeme, commfailure, commok, onbattery, and mains-
back in the directory c:\apcupsd\examples. To use them, you must modify
the SYSADMIN variable to have a valid email address, then copy the files
into the directory c:\apcupsd\etc\apcupsd.
Killpower under Windows
If your batteries become exhausted during a power failure and you want your
machine to automatically reboot when the power comes back, it is useful to
implement the killpower feature of the UPS where apcupsd sends the UPS
the command to shut off the power. In doing so, the power will be cut to
your PC and if your BIOS is properly setup, the machine will automatically
reboot when the power comes back. This is important for servers.
This feature is implemented on Unix systems by first requesting a system
shutdown. As a part of the shutdown, apcupsd is terminated by the system,
but the shutdown process executes a script where apcupsd is recalled after
the disks are synced and the machine is idle. Apcupsd then requests the
UPS to shut off the power (killpower).
Unfortunately on Windows, there is no such shutdown script that we are
aware of and no way for apcupsd to get control after the machine is idled.
If this feature is important to you, it is possible to do it by telling apcupsd
to immediately issue the killpower command after issuing the shutdown
request. The danger in doing so is that if the machine is not sufficiently
idled when the killpower takes place, the disks will need to be rescanned
(and there is a possibility of lost data however small). Generally, UPSes
have a shutdown grace period which gives sufficient time for the OS to
shutdown before the power is cut.
To implement this feature, you need to add the -p option to the apcupsd
command line that is executed by the system. Currently the procedure is
manual. You do so by editing the registry and changing the line:
