@radoondas Thanks a lot. What would be nice to also have a screenshot of the dashboard in the module docs file ... ;-)

[radoondas]

@ruflin yes! I will update PR.

@ruflin Should I put image to following path? metricbeat/docs/images

[ruflin]

@radoondas good question. I just realised that this is missing in the collect script. Put it under docs/images for the moment as you suggested.
