Prometheus apcupsd exporter

iodeveloper/prom-apcupsd-exporter:latest

Use cases

• Provides wide apcupsd metrics for prometheus.

  • apcupsd_input_*: input line metrics
  • apcupsd_output_*: output line metrics
  • apcupsd_battery_*: battery metrics
  • apcupsd_ups_*: UPS status and settings
  • apcupsd_shutdown_*: apcupsd shutdown settings

• Can be integrated with apccontrol signals such as powerout, startselftest and etc.

• Built-in websocket server allow to connect and notify web clients for events/signals. Example: lightweight status widget on pure js/css (responsive alternative to grafana for realtime monitoring).

• This exporter calculates events between previous and latest states. Changed fields and new events are broadcasting to connected clients via websocket.

Grafana example

Widget example

Websocket widget for pad (not included in this project): instant reaction for plug-out and plug-in. Status change: ONLINE -> ONBATTERY (powerout) -> ONLINE
