Newbie question

[Rob Pijpers]

Let me start to tell that I'm a newbie with Prometheus.

I have Prometheus and Grafana running on a Windows server and is used to collect data from my Homey domotica system, this works fine.

Now I want to collect data via an API call from a source using a web request via curl.

The output is in JSON format and looks as below:

{"ok":true,"type":"response","time":0.00040627799171489,"rv":{"value":8251.514},"systime":1596905673,"seq":1,"error":false}

I want to collect the "value" content in Prometheus every minute or so, but I don't know how to get this done.

So I really need some help from you.

Regards, Rob

You will need an exporter to convert that format into the Prometheus text format to allow it to be scraped.

I don't know if there is something already available, but if not it should be fairly straightforward to create something using the language of your choice and one of the Prometheus client libraries (eg. Python)

The https://github.com/prometheus-community/json_exporter might be a good option.

Hi Ben,

Could you help me getting started with this exporter, for example should this be installed on a separate server or in a container?

Thx, Rob
