# Open Hardware Monitor Client

A utility to fetch metrics from [Open Hardware Monitor](https://openhardwaremonitor.org/) instances by using it's web service.
It currently only supports two commands; printing to a console and a prometheus exporter.

## Stability

This package is under development and should not considered stable at this time.

## Install

This package is `go get`able by running:

```bash
$ go get git.buddy.wtf/buddy/open-hardware-monitor-client/cmd/ohwm-client
```

## Usage

```
$ ohwm-client help
NAME:
   ohwm-client - A new cli application

USAGE:
   ohwm-client [flags] <command> [flags]

DESCRIPTION:
   Open Hardware Manager Client

COMMANDS:
   print    pretty prints api result
   export   runs http exporter for prometheus
   help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --host value    open hardware monitor host [OSHW_HOST] (default: "127.0.0.1:8085") [$OHWM_HOST]
   --scheme value  open hardware monitor scheme (http/https) (default: "http") [$OHWM_SCHEME]
   --path value    open hardware monitor path (ie /data.json) (default: "/data.json") [$OHWM_PATH]
   --help, -h      show help
```

### Prometheus Exporter

The prometheus exporter converts the JSON format from the Open Hardware Monitor to the [OpenMetrics](https://openmetrics.io/) format used by prometheus.
The server responds to the /metrics endpoint.

```
$ ohwm-client export --http :9111
2019/10/01 18:43:38 listen on: :9111
2019/10/01 18:43:50 GET /metrics
```

### Print

Print will write the results to the console. Example output:

```
$ ohwm-client print
Sensor: Value (Min - Max)
