envstat -- utility to handle environmental sensors
envstat [-DfIlSTWx] [-c file] [-d device] [-i interval] [-s device:sensor,...] [-w width]
envstat is a utility that handles various aspects of the sensors regis- tered with the envsys(4) framework. It is capable of displaying sensor values as well as changing parameters and setting critical limits for the sensors. In display mode, column widths as well as displayed sensors are fully customizable. Critical limits or other properties can be set via the configuration file. If critical limits were set previously, the display mode will show the critical limits in addition to the current values. The following options are available: -c Accepts a file as argument to set properties for sensors in devices registered with the framework. See the envsys.conf(5) manual page for more information. -D Display the names of the drivers that were registered with the envsys(4) framework, one per line and some properties for the driver: refresh timeout value, for example. -d device Display only the sensors for the given device. This is useful when there are multiple devices registered and you want to only see results from a specific device. -f Display temperature values in degrees Fahrenheit. The default is to display temperature values in degrees Celsius. -I This flag skips the sensors with invalid state, these are normally shown using the "N/A" string by default. -i interval Repeat the display every interval seconds. Note that some devices do not provide fresh values on demand. See the individual devices manual page for meaningful values for interval. If not specified, or specified as 0, envstat produces one round of values and exits. -l List the names of all supported sensors, one per line. Use of this flag causes envstat to ignore all other option flags. -r This flag is provided for compatibility reasons and there's no need to use it. In the previous implementation, it was used to enable the row mode; this mode is now the default. -S This flag is used to restore defaults to all devices registered with the framework. This will remove all properties that were set in the configuration file to the setting that the drivers use by default. -s device:sensor,... Restrict the display to the named sensors. The pair device and sensor description must be supplied as a comma separated list. Device as well as sensor descriptions are case sensitive. -T Create and display max, min and average statistics for a sensor. Must be used with an interval, otherwise statistics cannot be col- lected up. Please note that to get realistic values a lower inter- val value should be used, but that will also increase overhead. -w width Use width as the column width for the output. Each column is addi- tionally separated by a single space. The default is the length of the longest sensor name. -W Display the warning alarm minimum and maximum levels instead of the critical alarm levels. -x Shows the property list used by the sysmon_envsys(9) framework that contains details about all registered drivers and sensors.
To display the ``charge'' sensor of the driver acpibat0 in one line every ten seconds: $ envstat -s "acpibat0:charge" -i 10 To list the drivers that are currently registered with envsys(4): $ envstat -D To display the sensors of the driver aiboost0: $ envstat -d aiboost0 To set all properties specified in the configuration file: $ envstat -c /etc/envsys.conf To remove all properties that were set previously in the configuration file: $ envstat -S To display statistics for all sensors and ignoring sensors with invalid states every second: $ envstat -ITi1

envstat appeared in NetBSD 1.5. It was completely rewritten from scratch for NetBSD 5.0.
The envstat utility that appeared in NetBSD 5.0 was written by Juan Romero Pardines. The previous version was written by Bill Squier. NetBSD 5.0 October 11, 2008 NetBSD 5.0
