The (gnu services pm)
module provides a Guix service definition for
the Linux Power Profiles Daemon, which makes power profiles handling
available over D-Bus.
The available profiles consist of the default ‘balanced’ mode, a ‘power-saver’ mode and on supported systems a ‘performance’ mode.
Importante: The
power-profiles-daemon
conflicts with other power management tools liketlp
. Using both together is not recommended.
This is the service type for the
Power
Profiles Daemon. The value for this service is a
power-profiles-daemon-configuration
.
To enable the Power Profiles Daemon with default configuration add this line to your services:
Data type representing the configuration of
power-profiles-daemon-service-type
.
power-profiles-daemon
(default: power-profiles-daemon
) (type: file-like)Package object of power-profiles-daemon.
El módulo (gnu services pm)
proporciona una definición de servicio
Guix para la herramienta de gestión de energía de Linux TLP.
TLP activa varios modos de ahorro de energía en el núcleo y en espacio de
usuaria. Al contrario que upower-service
, no es una herramienta de
monitorización pasiva, puesto que aplicará una nueva configuración
personalizada cada vez que se detecte una nueva fuente de
energía/alimentación. Puede encontrar más información en
la página de TLP.
EL tipo de servicio para la herramienta TLP. La configuración predeterminada
está optimizada para la vida de la batería en la mayoría de los sistemas,
pero puede modificarla al completo con las opciones que desee proporcionando
un objeto tlp-configuration
válido:
(service tlp-service-type
(tlp-configuration
(cpu-scaling-governor-on-ac (list "performance"))
(sched-powersave-on-bat? #t)))
Each parameter definition is preceded by its type; for example,
‘boolean foo’ indicates that the foo
parameter should be
specified as a boolean. Types starting with maybe-
denote parameters
that won’t show up in TLP config file when their value is left unset, or is
explicitly set to the %unset-value
value.

El módulo (gnu services pm)
proporciona una interfaz con thermald, un
servicio de escalado de frecuencia de la CPU que ayuda a prevenir el
sobrecalentamiento.
Este es el tipo de servicio para thermald, el daemon Thermal de Linux, que es responsable del control del estado térmico de los procesadores y la prevención del sobrecalentamiento.
Tipo de datos que representa la configuración de
thermald-service-type
.
adaptive?
(default: #f
)Use DPTF (Dynamic Power and Thermal Framework) adaptive tables when present.

The (gnu services pm)
module also provides a service definition for
PowerTOP, a power consumption analysis and
tuning tool. When started, it tunes Linux kernel settings to reduce power
consumption.
The service type for PowerTOP. No configuration is necessary. When the
service starts, it executes powertop --auto-tune
.
Available powertop-configuration
fields are:
powertop-configuration
parameter: package powertop ¶The PowerTOP package. Defaults to powertop
in the (gnu
packages linux)
module
The (gnu services power)
module provides a service definition for
apcupsd, a utility to interact with
APC (APC by Schneider Electric or formerly American Power
Conversion Corporation) UPS (Uninterruptible Power Supply)
devices. Apcupsd also works with some OEM (Original Equipment
Manufacturer)-branded products manufactured by APC.
The service type for apcupsd. For USB UPSes no configuration is necessary,
however tweaking some fields to better suit your needs might be desirable.
The defaults are taken from the upstream configuration and they are not very
conservative (for example, the default battery-level
of 5% may be
considered too low by some).
The default event handlers do send emails, read more in apcupsd-event-handlers.
Available apcupsd-configuration
fields are:
apcupsd
(default: apcupsd
) (type: package)The apcupsd
package to use.
shepherd-service-name
(default: apcupsd
) (type: symbol)The name of the shepherd service. You can add the service multiple times with different names to manage multiple UPSes.
auto-start?
(default: #t
) (type: boolean)Should the shepherd service auto-start?
pid-file
(default: "/var/run/apcupsd.pid"
) (type: string)The file name of the pid file.
debug-level
(default: 0
) (type: integer)The logging verbosity. Bigger number means more logs. The source code uses
up to 300
as debug level value, so a value of 999
seems
reasonable to enable all the logs.
run-dir
(default: "/var/run/apcupsd"
) (type: string)The directory containing runtime information. You need to change this if you desire to run multiple instances of the daemon.
name
(type: maybe-string)Use this to give your UPS a name in log files and such. This is particularly useful if you have multiple UPSes. This does not set the EEPROM. It should be 8 characters or less.
cable
(default: usb
) (type: enum-cable)The type of a cable connecting the UPS to your computer. Possible generic
choices are 'simple
, 'smart
, 'ether
and 'usb
.
Alternatively, a specific cable model number may be used: '940-0119A
,
'940-0127A
, '940-0128A
, '940-0020B
, '940-0020C
,
'940-0023A

,
'940-0625A
, 'M-04-02-2000
.
type
(default: usb
) (type: enum-type)The type of the UPS you have.
apcsmart
Newer serial character device, appropriate for SmartUPS models using a serial cable (not an USB).
usb
Most new UPSes are an USB.
net
Network link to a master apcupsd through apcupsd’s Network Information Server. This is used if the UPS powering your computer is connected to a different computer for monitoring.
snmp
SNMP network link to an SNMP-enabled UPS device.
netsnmp
Same as the SNMP above but requires use of the net-snmp library. Unless you
have a specific need for this old driver, you should use the 'snmp
instead.
dumb
An old serial character device for use with simple-signaling UPSes.
pcnet
A PowerChute Network Shutdown protocol which can be used as an alternative to an SNMP with the AP9617 family of smart slot cards.
modbus
A serial device for use with newest SmartUPS models supporting the MODBUS protocol.
device
(default: ""
) (type: string)For USB UPSes, usually you want to set this to an empty string (the default). For other UPS types, you must specify an appropriate port or address.
apcsmart
Set to the appropriate /dev/tty** device.
usb
A null string setting enables auto-detection, which is the best choice for most installations.
net
Set to hostname:port
.
snmp
Set to hostname:port:vendor:community
. The
hostname is the ip address or hostname of the UPS on the network. The
vendor can be can be "APC" or "APC_NOTRAP". "APC_NOTRAP" will disable
SNMP trap catching; you usually want "APC". The port is usually 161.
The community is usually "private".
netsnmp
Same as the 'snmp
.
dumb
Set to the appropriate /dev/tty** device.
pcnet
Set to ipaddr:username:passphrase:port
. The
ipaddr is the IP address of the UPS management card. The
username and the passphrase are the credentials for which the
card has been configured. The port is the port number on which to
listen for messages from the UPS, normally 3052. If this parameter is empty
or missing, the default of 3052 will be used.
modbus
Set to the appropriate /dev/tty** device. You can also leave it empty for MODBUS over USB or set to the serial number of the UPS.
poll-time
(default: 60
) (type: integer)The interval (in seconds) at which apcupsd polls the UPS for status. This setting applies both to directly-attached UPSes (apcsmart, usb, dumb) and networked UPSes (net, snmp). Lowering this setting will improve the apcupsd’s responsiveness to certain events at the cost of higher CPU utilization.
on-batery-delay
(default: 6
) (type: integer)The time in seconds from when a power failure is detected until we react to
it with an onbattery event. The 'powerout
event will be triggered
immediately when a power failure is detected. However, the
'onbattery
event will be trigger only after this delay.
battery-level
(default: 5
) (type: integer)If during a power failure, the remaining battery percentage (as reported by the UPS) is below or equal to this value, the apcupsd will initiate a system shutdown.
Nota:
battery-level
,remaining-minutes
, andtimeout
work in a conjunction, so the first that occurs will cause the initation of a shutdown.
remaining-minutes
(default: 3
) (type: integer)If during a power failure, the remaining runtime in minutes (as calculated internally by the UPS) is below or equal to this value, apcupsd will initiate a system shutdown.
Nota:
battery-level
,remaining-minutes
, andtimeout
work in a conjunction, so the first that occurs will cause the initation of a shutdown.
timeout
(default: 0
) (type: integer)If during a power failure, the UPS has run on batteries for this many seconds or longer, apcupsd will initiate a system shutdown. The value of 0 disables this timer.
Nota:
battery-level
,remaining-minutes
, andtimeout
work in a conjunction, so the first that occurs will cause the initation of a shutdown.
annoy-interval
(default: 300
) (type: integer)The time in seconds between annoying users (via the 'annoyme
event)
to sign off prior to system shutdown. 0 disables.
annoy-delay
(default: 60
) (type: integer)The initial delay in seconds after a power failure before warning users to get off the system.
no-logon
(default: disable
) (type: enum-no-logon)The condition which determines when users are prevented from logging in during a power failure.
kill-delay
(default: 0
) (type: integer)If this is non-zero, the apcupsd will continue running after a shutdown has been requested, and after the specified time in seconds attempt to kill the power. This is for use on systems where apcupsd cannot regain control after a shutdown.
net-server
(default: #f
) (type: boolean)If enabled, a network information server process will be started.
net-server-ip
(default: "127.0.0.1"
) (type: string)An IP address on which the NIS server will listen for incoming connections.
net-server-port
(default: 3551
) (type: integer)An IP port on which the NIS server will listen for incoming connections.
net-server-events-file
(type: maybe-string)If you want the last few EVENTS to be available over the network by the network information server, you must set this to a file name.
net-server-events-file-max-size
(default: 10
) (type: integer)The maximum size of the events file in kilobytes.
class
(default: standalone
) (type: enum-class)Normally standalone unless you share an UPS using an APC ShareUPS card.
mode
(default: disable
) (type: enum-mode)Normally disable unless you share an UPS using an APC ShareUPS card.
stat-time
(default: 0
) (type: integer)The time interval in seconds between writing the status file, 0 disables.
log-stats
(default: #f
) (type: boolean)Also write the stats as a logs. This generates a lot of output.
data-time
(default: 0
) (type: integer)The time interval in seconds between writing the data records to the log file, 0 disables.
facility
(type: maybe-string)The logging facility for the syslog.
event-handlers
(type: apcupsd-event-handlers)Handlers for events produced by apcupsd.
For a description of the events please refer to ‘man 8 apccontrol’.
