32.Os
33.Sh NAME
34.Nm envstat
35.Nd utility to handle environmental sensors
36.Sh SYNOPSIS
37.Nm
38.Op Fl DfIlSTWx
39.Op Fl c Ar file
40.Op Fl d Ar device
41.Op Fl i Ar interval
42.Op Fl s Ar "device:sensor,..."
43.Op Fl w Ar width
44.Sh DESCRIPTION
45.Nm
46is a utility that handles various aspects of the sensors
47registered with the
48.Xr envsys 4
49framework.
50It is capable of displaying sensor values as well as
51changing parameters and setting critical limits for the sensors.
52.Pp
53In display mode, column widths as well as displayed sensors
54are fully customizable.
55Critical limits or other properties can be set via the configuration file.
56If critical limits were set previously, the display mode will show
57the critical limits in addition to the current values.
58.Pp
59The following options are available:
60.Bl -tag -width flag
61.It Fl c
62Accepts a file as argument to set properties for sensors in
63devices registered with the framework.
64See the
65.Xr envsys.conf 5
66manual page for more information.
67.It Fl D
68Display the names of the drivers that were registered with
69the
70.Xr envsys 4
71framework, one per line and some properties for the driver: refresh timeout
72value, for example.
73.It Fl d Ar device
74Display only the sensors for the given
75.Ar device .
76This is useful when there are multiple devices registered and
77you want to only see results from a specific device.
78.It Fl f
79Display temperature values in degrees Fahrenheit.
80The default is to display temperature values in degrees Celsius.
81.It Fl I
82This flag skips the sensors with invalid state, these are normally
83shown using the
84.Qq N/A
85string by default.
86.It Fl i Ar interval
87Repeat the display every
88.Ar interval
89seconds.
90Note that some devices do not provide fresh values on demand.
91See the individual device's manual page for meaningful values for
92.Ar interval .
93If not specified, or specified as 0,
94.Nm
95produces one round of values and exits.
96.It Fl k
97Display temperature values in Kelvin.
98The default is to display temperature values in degrees Celsius.
99.It Fl l
100List the names of all supported sensors, one per line.
101Use of this flag causes
102.Nm
103to ignore all other option flags.
104.It Fl r
105This flag is provided for compatibility reasons and there's no need
106to use it.
107In the previous implementation, it was used to enable the
108row mode; this mode is now the default.
109.It Fl S
110This flag is used to restore defaults to all devices registered with
111the framework.
112This will remove all properties that were set in
113the configuration file to the setting that the drivers use by
114default.
115.It Fl s Ar "device:sensor,..."
116Restrict the display to the named sensors.
117The pair device and sensor description must be supplied as a comma separated list.
118Device as well as sensor descriptions are case sensitive.
119.It Fl T
120Create and display max, min and average statistics for a sensor.
121Must be used with an
122.Ar interval ,
123otherwise statistics cannot be collected up.
124Please note that to get realistic
125values a lower interval value should be used, but that will also increase
126overhead.
127.It Fl w Ar width
128Use
129.Ar width
130as the column width for the output.
131Each column is additionally separated by a single space.
132The default is the length of the longest sensor name.
133.It Fl W
134This option has no effect.
135It is retained for historical reasons.
136.It Fl x
137Shows the property list used by the
138.Xr sysmon_envsys 9
139framework that contains details about all registered drivers
140and sensors.
141.El
142.Sh EXAMPLES
143To display the
144.Dq charge
145sensor of the driver
146.Ar acpibat0
147in one line every ten seconds:
148.Pp
149.Dl $ envstat -s \*qacpibat0:charge\*q -i 10
150.Pp
151To list the drivers that are currently registered with
152.Xr envsys 4 :
153.Pp
154.Dl $ envstat -D
155.Pp
156To display the sensors of the driver
157.Ar aiboost0 :
158.Pp
159.Dl $ envstat -d aiboost0
160.Pp
161To set all properties specified in the configuration file:
162.Pp
163.Dl $ envstat -c /etc/envsys.conf
164.Pp
165To remove all properties that were set previously in the configuration
166file:
167.Pp
168.Dl $ envstat -S
169.Pp
170To display statistics for all sensors and ignoring sensors with
171invalid states every second:
172.Pp
173.Dl $ envstat -ITi1
