systemd systemd-report-hwmon@.service 8 systemd-report-hwmon@.service systemd-report-hwmon.socket systemd-report-hwmon Report hardware monitoring temperature sensor readings as system report metrics systemd-report-hwmon@.service systemd-report-hwmon.socket /usr/lib/systemd/systemd-report-hwmon systemd-report-hwmon@.service is a metrics source for systemd-report1. It reports the current readings of the temperature sensors exposed by the kernel's hardware monitoring (hwmon) subsystem, by implementing the io.systemd.Metrics Varlink interface on a socket linked into the /run/systemd/report/ directory. All devices of the hwmon subsystem are enumerated, and for each of their tempN_input attributes one io.systemd.HWMon.TemperatureCelsius gauge metric is reported, with the current temperature in degrees Celsius as value. The metric object is the name of the device the hwmon chip belongs to (for example coretemp.0, nvme0 or thermal_zone0). The following metric fields are set: chip The name of the hwmon chip, i.e. the contents of its name attribute, for example coretemp or nvme. Omitted if the attribute cannot be read. sensor The sensor name within the chip, i.e. tempN. Always set. label The human readable sensor label, i.e. the contents of the tempN_label attribute, for example Package id 0. Omitted if the sensor carries no label. systemd1 systemd-report1 Naming and data format standards for sysfs files
