IoT Edison exporter

Prometheus exporter for sensor metrics from Intel Edison.

Supported sensors:

  • Grove temperature sensor
  • Grove sound sensor
  • Grove light sensor

Build and run

Build on a machine using Go 1.5+ with GOPATH set:

git clone https://github.com/roman-vynar/edison_exporter.git
cd edison_exporter
go get -d
GOARCH=386 GOOS=linux go build edison_exporter.go

Also you can download the binary from Releases

Copy to Edison:

scp edison_exporter root@<Edison IP>:~/

Run:

root@edison:~# ./edison_exporter

Options

Name Description
-sensor.temperature.pin Analog pin number where temperature sensor is attached. (default "0")
-sensor.light.pin Analog pin number where light sensor is attached. (default "1")
-sensor.sound.pin Analog pin number where sound sensor is attached. (default "3")
-sensor.polling.interval Sensor polling interval. (default 5s)
-log.level value Only log messages with the given severity or above. Valid levels: [debug, info, warn, error, fatal, panic]. (default info)
-web.listen-address Address to listen on for web interface and telemetry. (default ":9122")
