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 trigger\&.

by default, \fBupsmon\fR(8) will run upssched as whatever user you have defined with RUN_AS_USER in \fBupsmon.conf\fR(8)\&. Make sure that user can create files and write to files in the path you use for PIPEFN and LOCKFN\&.

My recommendation: create a special directory for upssched, make it owned by your upsmon user, then use it for both\&.
|
|
.sp
|
|
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\&.
|
|
.PP
|
|
\fBLOCKFN\fR \fIfilename\fR
|
|
.RS 4
|
|
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\&.
|
|
.sp
|
|
You should put this in the same directory as PIPEFN\&.

\fBAT\fR \fInotifytype\fR \fIupsname\fR \fIcommand\fR
|
|
.RS 4
|
|
Define a handler for a specific event
|
|
\fInotifytype\fR
|
|
on UPS
|
|
\fIupsname\fR\&.
|
|
\fIupsname\fR
|
|
can be the special value * to apply this handler to every UPS\&.
|
|
.sp
|

This will perform the command
|
|
\fIcommand\fR
|
|
when the
|
|
\fInotifytype\fR
|
|
and
|
|
\fIupsname\fR
|
|
match the current activity\&. Possible values for
|
|
\fIcommand\fR

are:

.PP

\fBSTART\-TIMER\fR \fItimername\fR \fIinterval\fR
|
|
.RS 4
|
|
Start a timer of
|
|
\fIinterval\fR
|
|
seconds\&. When it triggers, it will pass the argument
|
|
\fItimername\fR
|
|
as an argument to your CMDSCRIPT\&.
|
|
.sp
|

Example:
|
|
.sp
|
|
Start a timer that\(cqll execute when any UPS (*) has been gone for 10 seconds

\fBCANCEL\-TIMER\fR \fItimername\fR [\fIcmd\fR]
|
|
.RS 4
|

Cancel a running timer called

\fItimername\fR, if possible\&. If the timer has passed then pass the optional argument
|
|
\fIcmd\fR
|
|
to CMDSCRIPT\&.
|
|
.sp
|

Example:
|
|
.sp
|
|
If a specific UPS (myups@localhost) comes back online, then stop the timer before it triggers
|
|
.sp
|
|
.if n \{\

.RS 4

Immediately pass

as an argument to CMDSCRIPT\&.
|

.sp
|

Example:
|

If any UPS (*) reverts to utility power, then execute
|

ups\-back\-on\-line
|
|
via CMDSCRIPT\&.
|

Note that any AT that matches both the \fInotifytype\fR and the \fIupsname\fR for the current event will be used\&.
