# Power Supply Plugin: proc.plugin Module: /sys/class/power_supply ## Overview This integration monitors Power supply metrics, such as battery status, AC power status and more. This collector is supported on all platforms. This collector supports collecting metrics from multiple instances of this integration, including remote instances. ### Default Behavior #### Auto-Detection This integration doesn't support auto-detection. #### Limits The default configuration for this integration does not impose any limits on data collection. #### Performance Impact The default configuration for this integration is not expected to impose a significant performance impact on the system. ## Metrics Metrics grouped by *scope*. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. ### Per power device Labels: | Label | Description | |:-----------|:----------------| | device | TBD | Metrics: | Metric | Dimensions | Unit | |:------|:----------|:----| | powersupply.capacity | capacity | percentage | | powersupply.charge | empty_design, empty, now, full, full_design | Ah | | powersupply.energy | empty_design, empty, now, full, full_design | Wh | | powersupply.voltage | min_design, min, now, max, max_design | V | ## Alerts The following alerts are available: | Alert name | On metric | Description | |:------------|:----------|:------------| | [ linux_power_supply_capacity ](https://github.com/netdata/netdata/blob/master/health/health.d/linux_power_supply.conf) | powersupply.capacity | percentage of remaining power supply capacity | ## Setup ### Prerequisites No action required. ### Configuration #### File There is no configuration file. #### Options There are no configuration options. #### Examples There are no configuration examples.
