Docker Image with Telegraf, InfluxDB and Grafana

This is a Docker image based on the Docker Image with Telegraf (StatsD), InfluxDB and Grafana from Samuele Bistoletti and Docker Image with InfluxDB and Grafana from Phil Hawthorne. The main purpose of this image is to be used to show data from a Domoticz installation and Synology NAS, which hosted this image.

The main points of this image are:

• Persistence is supported via mounting volumes to a Docker container.
• Grafana will store its data in SQLite files instead of a MySQL table on the container, so MySQL is not installed.
• Added snmp packages and Synology NAS MIBS.

Versions

• Ubuntu: 20.04
• InfluxDB: 1.8.3
• Chronograf: 1.8.9.1
• Telegraf: 1.16.3
• Grafana: 7.3.5
