upssched.conf - Configuration for upssched timer program
This file controls the operations of upssched(8), the timer-based
helper program for upsmon(8).
Required. This must be above any AT lines. This script is used to
invoke commands when your timers are triggered. It receives a
single argument which is the name of the timer that caused it to
Required. This sets the file name of the socket which will be used
for interprocess communications. This should be in a directory
where normal users can’t create the file, due to the possibility of
symlinking and other evil.
if you are running Solaris or similar, the permissions that
upssched sets on this file are not enough to keep you safe. If your
OS ignores the permissions on a FIFO, then you MUST put this in a
by default, upsmon(8) will run upssched as whatever user you have
defined with RUN_AS_USER in upsmon.conf(8). Make sure that user can
create files and write to files in the path you use for PIPEFN and
My recommendation: create a special directory for upssched, make it
owned by your upsmon user, then use it for both.
The stock version of the upssched.conf ships with PIPEFN disabled to
make you visit this portion of the documentation and think about how
your system works before potentially opening a security hole.
Required. upssched attempts to create this file in order to avoid a
race condition when two events are dispatched from upsmon at nearly
the same time. This file will only exist briefly. It must not be
created by any other process.
You should put this in the same directory as PIPEFN.
AT notifytype upsname command
Define a handler for a specific event notifytype on UPS upsname.
upsname can be the special value * to apply this handler to every
This will perform the command command when the notifytype and
upsname match the current activity. Possible values for command
START-TIMER timername interval
Start a timer of interval seconds. When it triggers, it will
pass the argument timername as an argument to your CMDSCRIPT.
Start a timer that’ll execute when any UPS (*) has been gone
for 10 seconds
AT COMMBAD * START-TIMER upsgone 10
CANCEL-TIMER timername [cmd]
Cancel a running timer called timername, if possible. If the
timer has passed then pass the optional argument cmd to
If a specific UPS (myups@localhost) comes back online, then
stop the timer before it triggers
AT COMMOK myups@localhost CANCEL-TIMER upsgone
Immediately pass command as an argument to CMDSCRIPT.
If any UPS (*) reverts to utility power, then execute
ups-back-on-line via CMDSCRIPT.
AT ONLINE * EXECUTE ups-back-on-line
Note that any AT that matches both the notifytype and the upsname for
the current event will be used.
For a complete list of notifytype possible values, refer to the section
NOTIFY EVENTS in upsmon(8).
