I'd like to create a custom Metricbeat Metricset based on the Windows WMI. I've looked at the [developer guide](https://www.elastic.co/guide/en/beats/devguide/current/metricbeat-developer-guide.html), and although I'm an experienced C# developer, decided that it's a bit over my head.

All I need is a good reference implementation that I can customize with the WMI counters I need. I'm looking for a clean, crisp, well documented implementation I can use as a template.

Is such a template available?

If you run the generator as mentioned in the developer guide you should already get a pretty good basic structure with most of the relevant code bits. Then you can have a look at wmibeat ([https://github.com/eskibars/wmibeat](https://github.com/eskibars/wmibeat)) which has an implementation to access wmi data. Combining the two should get you pretty far.

Let us know if you hit a wall.
