ENVSTAT(8) System Manager's Manual ENVSTAT(8) NAME envstat -- utility to handle environmental sensors SYNOPSIS envstat [-DfIklSTWx] [-c file] [-d device] [-i interval] [-s device:sensor,...] [-w width] DESCRIPTION envstat is a utility that handles various aspects of the sensors registered 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 devices that are currently registered with the envsys(4) framework, one per line, along with some properties for the device (for example, its refresh timeout value). -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 device's manual page for meaningful values for interval. If not specified, or specified as 0, envstat produces one round of values and exits. -k Display temperature values in Kelvin. The default is to display temperature values in degrees Celsius. -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 devices use by default. -s device:sensor,... Restrict the display to the named devices and sensors. The pair device and sensor description must be supplied as a comma separated list. Device as well as sensor descriptions are case sensitive. Note that the order of the arguments given does not influence the order of output. -T Create and display max, min and average statistics for a sensor. Must be used with an interval, otherwise statistics cannot be collected up. Please note that to get realistic values a lower interval value should be used, but that will also increase overhead. -w width Use width as the column width for the output. Each column is additionally separated by a single space. The default is the length of the longest sensor name. -W This option has no effect. It is retained for historical reasons. -x Shows the raw XML property list used by the sysmon_envsys(9) framework that contains details about all registered devices and sensors. UNITS The display mode may show some values with abbreviated units; for example: A Amperes Ah Ampere-hours degC degrees Celsius degF degrees Fahrenheit K Kelvin Ohms Ohms RPM Revolutions per minute V Volts DC VAC Volts AC W Watts Wh Watt-hours %rH relative Humidity EXAMPLES To display the ``charge'' sensor of the device acpibat0 in one line every ten seconds: $ envstat -s "acpibat0:charge" -i 10 To list the devices that are currently registered with envsys(4): $ envstat -D To display the sensors of the device aibs0: $ envstat -d aibs0 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 SEE ALSO units(1), proplib(3), acpiacad(4), acpibat(4), acpitz(4), admtemp(4), aibs(4), amdtemp(4), aps(4), arcmsr(4), battery_pmu(4), cac(4), coretemp(4), dbcool(4), envctrl(4), envsys(4), finsio(4), hythygtemp(4), ipmi(4), itesio(4), lm(4), lmtemp(4), mfi(4), nsclpcsio(4), owtemp(4), pic16lc(4), smsc(4), tctrl(4), thinkpad(4), tm121temp(4), ug(4), viaenv(4), envsys.conf(5) HISTORY envstat appeared in NetBSD 1.5. It was completely rewritten from scratch for NetBSD 5.0. AUTHORS The envstat utility that appeared in NetBSD 5.0 was written by Juan Romero Pardines. The previous version was written by Bill Squier. BUGS When displaying statistics using the -T option, the average value is an average of the minimum, maximum, and current sensor values. It is not an average of all current values displayed during the session. NetBSD 7.1.2 May 18, 2014 NetBSD 7.1.2
