.Sh NAME
.Nm envsys.conf
.Nd configuration file for the
.Xr envsys 4
framework
.Sh SYNOPSIS
.Nm envstat
.Op Fl S
.Op Fl c Ar /etc/envsys.conf
.Sh DESCRIPTION
The
.Nm
file configures all the features provided by the
.Xr envsys 4
framework.
It consists of a series of device and sensor blocks.
Each sensor block defines a group of
.Em properties .
The file format is free-form: new line markers and indentation are
ignored.
Comments start with a
.Sq #
sign and extend until the end of line.
.Pp
A
.Em property
is like a variable assignment.
It has a name, which goes to the left of the equal sign, and a value,
which goes to the right.
The assignment ends with a semicolon.
It looks like:
.Pp
.Dl name = value;
.Pp
There is no difference between string or integer values when defining them.
The value must be surrounded by double quotes if it contains whitespace.
.Pp
There can be multiple groups of devices and multiple groups of sensors
in the configuration file.
.Pp
A device block consists of one or more sensor blocks and one or more global
properties.
It has the following syntax:
.Bd -literal -offset indent
	device_name {
		prop = value;
		...
        	sensor0 {
			prop = value;
        		...
		}
		...
		sensorN {
			prop = value;
			...
		}
	}
	...
.Ed
.Pp
Device names are those shown by the
.Ql envstat -D
command; sensor blocks are named by the index position in which they are shown.
.Pp
For example, if we have the following output from the
.Xr envstat 8
command:
.Bd -literal -offset indent
  CPU Temperature:     32.000 degC
   MB Temperature:     37.000 degC
    Vcore Voltage:      1.232 V
     +3.3 Voltage:      3.248 V
       +5 Voltage:      4.992 V
      +12 Voltage:     11.985 V
    CPU FAN Speed:       1250 RPM
.Ed
.Pp
.Ql sensor0
corresponds to the
.Em CPU Temperature
sensor and
.Ql sensor6
corresponds to the
.Em CPU FAN Speed
sensor.
.Pp
There is another way that will give you the correct index
sensor; the
.Ql envstat -x
command will print the raw XML property list.
You only have to find the
.Em index
object in the appropriate dictionary.
The object will be shown as:
.Bd -literal -offset indent
	\*[Lt]key\*[Gt]index\*[Lt]/key\*[Gt]
	\*[Lt]string\*[Gt]sensor2\*[Lt]/string\*[Gt]
.Ed
.Pp
Invalid sensors and devices will be detected by the
.Xr envstat 8
parser and will be reported as errors.
.Pp
The following properties are provided for sensor blocks (please note that
not all properties apply to all type of sensors):
.Bl -tag -width ident
.It critical-capacity = 10;
.Pp
Sets a critical capacity limit property of 10
percent in a battery sensor.
Battery sensors are those that report a percentage from the
.Xr envstat 8
output.
.Pp
It is possible to find out if the sensor accepts this property
by running
.Ql envstat -x
and looking if the
.Em want-percentage
object is defined as
.Em true
on its dictionary.
For example:
.Bd -literal -offset indent
	\*[Lt]key\*[Gt]want-percentage\*[Lt]/key\*[Gt]
	\*[Lt]true/\*[Gt]
.Ed
.Pp
Only a value between 0 and 100 is allowed.
When the limit is reached in the sensor, a
.Em critical-capacity
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
.Pa /etc/powerd/scripts/sensor_battery .
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar CritMin .
.It warning-capacity = 20;
.Pp
Sets a warning capacity limit property of 20
percent in a battery sensor.
Battery sensors are those that report a percentage from the
.Xr envstat 8
output.
.Pp
It is possible to find out if the sensor accepts this property
by running
.Ql envstat -x
and looking if the
.Em want-percentage
object is defined as
.Em true
on its dictionary.
For example:
.Bd -literal -offset indent
	\*[Lt]key\*[Gt]want-percentage\*[Lt]/key\*[Gt]
	\*[Lt]true/\*[Gt]
.Ed
.Pp
Only a value between 0 and 100 is allowed.
When the limit is reached in the sensor, a
.Em warning-capacity
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
.Pa /etc/powerd/scripts/sensor_battery .
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar WarnMin .
.It high-capacity = 90;
.Pp
Sets a high capacity limit property of 90
percent in a battery sensor.
Battery sensors are those that report a percentage from the
.Xr envstat 8
output.
.Pp
It is possible to find out if the sensor accepts this property
by running
.Ql envstat -x
and looking if the
.Em want-percentage
object is defined as
.Em true
on its dictionary.
For example:
.Bd -literal -offset indent
	\*[Lt]key\*[Gt]want-percentage\*[Lt]/key\*[Gt]
	\*[Lt]true/\*[Gt]
.Ed
.Pp
Only a value between 0 and 100 is allowed.
When the limit is reached in the sensor, a
.Em high-capacity
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
.Pa /etc/powerd/scripts/sensor_battery .
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar WarnMax .
.It maximum-capacity = 99;
.Pp
Sets a warning capacity limit property of 99
percent in a battery sensor.
Battery sensors are those that report a percentage from the
.Xr envstat 8
output.
.Pp
It is possible to find out if the sensor accepts this property
by running
.Ql envstat -x
and looking if the
.Em want-percentage
object is defined as
.Em true
on its dictionary.
For example:
.Bd -literal -offset indent
	\*[Lt]key\*[Gt]want-percentage\*[Lt]/key\*[Gt]
	\*[Lt]true/\*[Gt]
.Ed
.Pp
Only a value between 0 and 100 is allowed.
When the limit is reached in the sensor, a
.Em warning-capacity
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
.Pa /etc/powerd/scripts/sensor_battery .
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar WarnMin .
.It critical-max = 70C;
.Pp
Sets a critical maximum limit property in a sensor.
Note that in this example, we are specifying the
.Ql C
keyword at the end; that means that this will only be valid for
.Em temperature
sensors and that the value is specified as degrees
.Em Celsius .
If degrees Fahrenheit are wanted, just use the letter
.Em F ,
as in:
.Bd -literal -offset indent
critical-max = 140F;
.Ed
.Pp
To know sensor type, you have to look at the
.Em type
object in the XML property list.
Remember: the XML property list has
all the information that the application uses to print the values!
.Pp
Other sensors that are not of
.Em temperature
type must not include the final character for the unit.
A dot is allowed in the value, if it corresponds to the
range that the sensor is reporting.
When the limit has been reached in the sensor, a
.Em critical-over
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
the appropriate
.Pa /etc/powerd/scripts/sensor_foo
script (depending on the sensor's type).
.Pp
Please note that this property cannot be set in battery capacity sensors
(those that have the
.Em want-percentage
object in their dictionary).
This rule applies for the
.Ql critical-min ,
.Ql warning-max ,
and
.Ql warning-min
properties too.
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar CritMax .
.It critical-min = 1.230;
.Pp
Sets a critical minimum limit property in a sensor.
The rules for
.Em critical-max ,
.Em critical-min ,
.Em warning-max ,
and
.Em warning-min
are the same.
When the limit has been reached in the sensor, a
.Em critical-under
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
the appropriate
.Pa /etc/powerd/scripts/sensor_foo
script (depending on the sensor's type).
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar CritMin .
.It warning-max = 70C;
.Pp
Sets a warning maximum limit property in a sensor.
The rules for
.Em critical-max ,
.Em critical-min ,
.Em warning-max ,
and
.Em warning-min
are the same.
When the limit has been reached in the sensor, a
.Em warning-over
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
the appropriate
.Pa /etc/powerd/scripts/sensor_foo
script (depending on the sensor's type).
.Pp
Please note that this property cannot be set in battery capacity sensors
(those that have the
.Em want-percentage
object in their dictionary).
This rule applies for the
.Ql warning-min
property too.
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar WarnMax .
.It warning-min = 1.230;
.Pp
Sets a critical minimum limit property in a sensor.
The rules for
.Em critical-max ,
.Em critical-min ,
.Em warning-max ,
and
.Em warning-min
are the same.
When the limit has been reached in the sensor, a
.Em warning-under
event will be sent to the
.Xr powerd 8
daemon (if running) and will execute the block for this event in
the appropriate
.Pa /etc/powerd/scripts/sensor_foo
script (depending on the sensor's type).
.Pp
If this property is set, its value will be shown in the
.Xr envstat 8
display output with a column named
.Ar WarnMin .
.It description = string
.Pp
Sets a new description in a sensor.
You can set this property in
all sensors, except that you won't be able to set a description
that is currently used for the specified device.
.It rfact = 56000
.Pp
Sets a new resistor factor property in a sensor.
This property is only allowed in
.Em Voltage
sensors and
.Em only
if the device has enabled the appropriate flag for the mentioned
sensor.
The resistor factor may be used to change the behavior
of the value returned by the device.
.Pp
If a sensor supports this, the
.Em allow-rfact
object appears enabled (true) in the dictionary.
.El
.Pp
The following properties are available for device blocks:
.Bl -tag -width ident
.It refresh-timeout = 10s
.Pp
This property sets the refresh timeout value in a device, and will be used
to refresh data and check for critical conditions any time the timeout
is met.
The value may be specified in seconds, minutes or hours.
To specify the value in seconds, the
.Em s
character must be appended last, if minutes is desired, a
.Em m
and a
.Em h
for hours.
For example
.Em 10s
for 10 seconds or
.Em 1h
for one hour.
