Apcupsd

Docker Pulls GitHub Stars

Description

Apcupsd is a dockerized Python script that will send data from apcupsd to influxdb. You can then visualize the influxdb data in Grafana/Prometheus.

First you need to install apcupsd on your host. The command will vary depending on what Linux OS you are using. After you install apcupsd on your host, there are some changes that need to take place in your apcupsd.conf file. Again, the location of this file varies by OS, however, for Ubuntu based systems you can find this file in /etc/apcupsd/.

By default acpupsd it is set to listen on 127.0.0.1. DockSTARTer (DS) does not run containers on host mode so your container will not be able to communicate with your apcupsd service. You need to open the apcupsd.conf file and search for NISIP. You need to change the IP address listed there to your local IP. Once you do this, you need to restart your apcupsd service so new settings take place.

The docker image DS uses makes uses of NOMPOWER on your UPS. If your UPS does not have NOMPOWER, you will need to add an override to your existing DS installation and set a new environment variable called WATTS under environment which will need to equal the rated max power for your UPS, e.g: 1000. To find whether your UPS has NOMPOWER or not, you can run apcaccess | grep "NOMPOWER".

Here is a great guide for exporting the influxdb data to Grafana. Just scroll down to the UPS Dashboard bit.
