.SH "DESCRIPTION"
|
||
|
|
.sp
|
||
|
|
This file is read by the driver controller \fBupsdrvctl\fR(8), the UPS drivers that use the common core (see \fBnutupsdrv\fR(8), and \fBupsd\fR(8))\&. The file begins with global directives, and then each UPS has a section which contains a number of directives that set parameters for that UPS\&.
|
||
|
|
.sp
|
||
|
|
A UPS section begins with the name of the UPS in brackets, and continues until the next UPS name in brackets or until EOF\&. The name "default" is used internally in upsd, so you can\(cqt use it in this file\&.
|
||
|
|
.sp
|
||
|
|
You must define the \fIdriver\fR and \fIport\fR elements for each entry\&. Anything after that in a section is optional\&. A simple example might look like this:
|
||
|
|
.sp
|
||
|
|
.if n \{\
|
||
|
|
.RS 4
|
||
|
|
.\}
|
||
|
|
.nf
|
||
|
|
[myups]
|
||
|
|
driver = blazer_ser
|
||
|
|
port = /dev/ttyS0
|
||
|
|
desc = "Web server UPS"
|
||
|
|
.fi
|
||
|
|
.if n \{\
|
||
|
|
.RE
|
||
|
|
.\}
|
||
|
|
.sp
|
||
|
|
A slightly more complicated version includes some extras for the hardware\-specific part of the driver:
|
||
|
|
.sp
|
||
|
|
.if n \{\
|
||
|
|
.RS 4
|
||
|
|
.\}
|
||
|
|
.nf
|
||
|
|
[bigups]
|
||
|
|
driver = apcsmart
|
||
|
|
port = /dev/cua00
|
||
|
|
cable = 940\-0095B
|
||
|
|
sdtype = 2
|
||
|
|
desc = "Database server UPS"
|
||
|
|
.fi
|
||
|
|
.if n \{\
|
||
|
|
.RE
|
||
|
|
.\}
|
||
|
|
.sp
|
||
|
|
In this case, the \fBapcsmart\fR(8) driver will receive variables called "cable" and "sdtype" which have special meanings\&. See the man pages of your driver(s) to learn which variables are supported and what they do\&.
|
||
|
|
.SH "GLOBAL DIRECTIVES"
|
||
|
|
.PP
|
||
|
|
\fBchroot\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. The driver will chroot(2) to this directory during initialization\&. This can be useful when securing systems\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBdriverpath\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. Path name of the directory in which the UPS driver executables reside\&. If you don\(cqt specify this, the programs look in a built\-in default directory, which is often /usr/local/ups/bin\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBmaxstartdelay\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. Same as the UPS field of the same name, but this is the default for UPSes that don\(cqt have the field\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBpollinterval\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. The status of the UPS will be refreshed after a maximum delay which is controlled by this setting\&. This is normally 2 seconds\&. This may be useful if the driver is creating too much of a load on your system or network\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBuser\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. If started as root, the driver will setuid(2) to the user id associated with
|
||
|
|
\fIusername\fR\&.
|
||
|
|
.RE
|
||
|
|
.SH "UPS FIELDS"
|
||
|
|
.PP
|
||
|
|
\fBdriver\fR
|
||
|
|
.RS 4
|
||
|
|
Required\&. This specifies which program will be monitoring this UPS\&. You need to specify the one that is compatible with your hardware\&. See
|
||
|
|
\fBnutupsdrv\fR(8)
|
||
|
|
for more information on drivers in general and pointers to the man pages of specific drivers\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBport\fR
|
||
|
|
.RS 4
|
||
|
|
Required\&. This is the serial port where the UPS is connected\&. On a Linux system, the first serial port usually is
|
||
|
|
\fI/dev/ttyS0\fR\&. On FreeBSD and similar systems, it probably will be
|
||
|
|
\fI/dev/cuaa0\fR\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBsdorder\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. When you have multiple UPSes on your system, you usually need to turn them off in a certain order\&. upsdrvctl shuts down all the 0s, then the 1s, 2s, and so on\&. To exclude a UPS from the shutdown sequence, set this to \-1\&.
|
||
|
|
.sp
|
||
|
|
The default value for this parameter is 0\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBdesc\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. This allows you to set a brief description that upsd will provide to clients that ask for a list of connected equipment\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBnolock\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. When you specify this, the driver skips the port locking routines every time it starts\&. This may allow other processes to seize the port if you start more than one accidentally\&.
|
||
|
|
.sp
|
||
|
|
You should only use this if your system won\(cqt work without it\&.
|
||
|
|
.sp
|
||
|
|
This may be needed on Mac OS X systems\&.
|
||
|
|
.RE
|
||
|
|
.PP
|
||
|
|
\fBmaxstartdelay\fR
|
||
|
|
.RS 4
|
||
|
|
Optional\&. This can be set as a global variable above your first UPS definition and it can also be set in a UPS section\&. This value controls how long upsdrvctl will wait for the driver to finish starting\&. This keeps your system from getting stuck due to a broken driver or UPS\&.
|
||
|
|
.sp
|
||
|
|
The default is 45 seconds\&.
|
||
|
|
.RE
|
||
|
|
.sp
|
||
|
|
All other fields are passed through to the hardware\-specific part of the driver\&. See those manuals for the list of what is allowed\&.
|

.SH "INTEGRATION"

.sp
|
||
|
|
\fBupsdrvctl\fR(8) uses this file to start and stop the drivers\&.
|
||
|
|
.sp
|
||
|
|
The drivers themselves also obtain configuration data from this file\&. Each driver looks up its section and uses that to configure itself\&.
|
||
|
|
.sp
|
||
|
|
\fBupsd\fR(8) learns about which UPSes are installed on this system by reading this file\&. If this system is called "doghouse" and you have defined a UPS in your \fBups\&.conf\fR called "snoopy", then you can monitor it from \fBupsc\fR(8) or similar as "snoopy@doghouse"\&.
