Transmission Exporter for Prometheus

This is a fork of Metalmatze's tranmission exporter. A few things were fixed and others removed to make my life easier.

Prometheus exporter for Transmission metrics, written in Go.

Changes done on this fork

• The Dockerfile was changed to build the transmission-exporter binary during docker build step. Previously it seems the Go binary was expected to be built outside the Dockerfile
• Removed .env support -- now only environment variables can be used to configure the exporter
• Added some debugging and an argument check on main.go 'cause I mess up environment variables sometimes

Building and launching it with Docker

docker build . -t transmission-exporter
docker run \
    -p 19091:19091 \
    -e TRANSMISSION_ADDR='http://192.168.1.112:9091' \
    -e TRANSMISSION_USERNAME=transmission \
    -e TRANSMISSION_PASSWORD=transmission \
    transmission-exporter

Be sure to change your parameters to point to your transmission instance. http://192.168.1.112:9091 is an address on my network, you certainly want to change that. Consider adding -d and --restart unless-stopped to the docker run above if you want the container to keep running across system restarts (aka as a service)
