# 1-wire temperature metrics with prometheus
|
|
|
|
This is a simple package providing the temperature of a 1-wire sensor such as the DH1820 as prometheus metrics. It reads
|
|
the `w1_slave` file at `/sys/bus/w1/devices/<sensor>`, parses it and provides the read temperature at a webserver
|
|
running on port 2112 at `/metrics`.
|
|
|
|
## Usage
|
|
|
|
Simply run the compiled program and provide the id of the sensor with the `-s` flag. The id is the name of the folder at
|
|
`/sys/bus/w1/devices/` containing the `w1_slave` file.
|
|
|
|
## Building
|
|
|
|
To build this package for the raspberry pi zero:
|
|
|
|
```bash
|
|
GOOS=linux GOARCH=arm GOARM=6 go build -o 1-wire-temp-arm
|
|
```
|
|
|
|
To build for all other Pi's:
|
|
|
|
```bash
|
|
GOOS=linux GOARCH=arm GOARM=7 go build -o 1-wire-temp-arm
|
|
```
