Temperature temperature probe for BIORCELL 3D.

Build with a MCP9600 thermocouple amplifier and a (RaspberryPi)[https://www.raspberrypi.org/].

Written in Golang.

client/collectd-probe: Daemon gathering MCP9600 informations and sending them to the collectd server.

Compile for RaspberryPi with:

    env GOOS=linux GOARCH=arm GOARM=5 go build .

server/collectd: Collectd server configuration.

Uses 3 plugins:

• network: listening for collectd-probe informations
• rrdtool: writing informations in the rrd format (used by Facette)
• csv: writing informations in the csv format (used by the notifier)

    // configure collectd.conf
    collectd -C ./collectd.conf
    cp types.db.custom /etc/collectd/

server/facette: Facette graph frontend configuration (as a Docker container) using rrd as unique provider.

    // configure etc/facette.yaml
    // configure docker-compose.yml
    docker-compose up -d

server/notifier: Daemon reading the csv informations and sending notifications. Use the Facette API to retrieve probe names. Min, Max temperature and notification threshold are given as arguments.

    // mandatory argument format:
    // probeName:minTemp:maxTemp:thresholdRate
    // - name must exactly match a Facette source
    // - minTemp, maxTemp: int or float
    // - thresholdRate: a Golang time.Duration
    notifier probe-fridge1:-10.5:-2:10m
    // for additionnal flags
    notifier --help 

The notifier should be removed in the future to use the built in collectd notification system. The collectd Golang library used by the collect-probe does not send notifications yet.
