Nut upsuser - Jan 2007 - Meaning of ups.delay.*

Hi all!

As I'm currently porting the HP PowerTrust driver from nut-1.4.3, I have
a question regarding ups.delay.*.

The PTs can delay the Shutdown/Restart and Kill commands by an arbitrary
number of seconds, i.e. they wait for n seconds and then shutdown or
kill. The delay for the restart after the shutdown can't be changed.
Which of the ups.delay.* variables correspond to these values?

Regards,
Jakob Haufe

The grace period before shutting down the UPS, is 'ups.delay.shutdown'.
The 'ups.delay.start' parameter is used to specify a time to wait before
switching on the load, while the 'ups.delay.reboot' specifies the time
to
stay off when rebooting the UPS.

Basically the only time you should add a delay is when a user explicitly
asks for it (so with the instant command 'shutdown.reboot.graceful').
You
may use a delay too for 'shutdown.stayoff' too since usually this
instant
command will be the cause of a user action.

In any case, calling 'upsdrv_shutdown()' should shutdown the UPS with
(virtually) no delay.

See my answer on the development list <nut-upsdev@lists.alioth.debian.org>
