apcupsd-influxdb-exporter

Build an x86_64 or ARM compatible Docker image that will output commonly used UPS device statistics to an influxdb database using an included version of the APCUPSd tool. Dockerfiles included for both intel and ARM (RaspberryPi or comparable) chipsets.

How to build

Building the image is straight forward:

• Git clone this repo
• docker build -t bgulla/apcupsd-influxdb-exporter .

Environment Variables

These are all the available environment variables, along with some example values, and a description.

Environment Variable	Example Value	Description
WATTS	1500	if your ups doesn't have NOMPOWER, set this to be the rated max power, if you do have NOMPOWER, don't set this variable
APCUPSD_HOST	192.168.1.100	host running apcupsd
INFLUXDB_HOST	192.168.1.101	host running influxdb
HOSTNAME	unraid	host you want to show up in influxdb, optional defaults to apcupsd-influxdb-exporter
INFLUXDB_DATABASE	apcupsd	db name for influxdb. optional, defaults to apcupsd
INFLUXDB_USER	myuser	optional, defaults to empty
INFLUXDB_PASSWORD	pass	optional, defaults to empty
INFLUXDB_PORT	8086	optional, defaults to 8086
VERBOSE	true	if anything but true docker logging will show no output
UPS_ALIAS	server_closet	an additional influxdb tag to the influxdb output

How to Use

Prereqs

This docker image assumes that you already have an instance of apcupsd running. If you want to deploy one via docker, run the following:

docker run -ti --rm \
    --name="apcupsd-tcp" \
    -p 3551:3551 \
    --privileged \
    bgulla/apcupsd-tcp

Run docker container directly

docker run --rm  -d --name="apcupsd-influxdb-exporter" \
    -e "WATTS=600" \
    -e "HOSTNAME=unraid" \
    -e "INFLUXDB_HOST=10.0.1.11" \
    -e "APCUPSD_HOST=10.0.1.11" \
    -t bgulla/apcupsd-influxdb-exporter

Note: if your UPS does not include the NOMPOWER metric, you will need to include the WATTS environment variable in order to compute the live-power consumption metric.

Run from docker-compose

version: '3'
services:
  apcupsd-influxdb-exporter:
    image: bgulla/apcupsd-influxdb-exporter
    container_name: apcupsd-influxdb-exporter
    restart: always
    environment:
      WATTS: 1500
      APCUPSD_HOST: 10.0.1.11
      INFLUXDB_HOST: 10.0.1.11
      HOSTNAME: unraid

If you want to debug the apcaccess output or the send to influxdb, set the environment variable "VERBOSE" to "true"
