Hey @jwcastillo, thanks for your contribution :bow:

@ppcano I assigned you as a reviewer so we have more opinions here

Nice job, @jwcastillo.

I doubt whether to include the Apdex metric or not. Neither Grafana pre-built dashboards nor k6 Cloud present the Apdex score by default. Initially, we aim for consistency across OSS and commercial dashboards. @dgzlopes, wdyt?

Yeah, lovely PR! Thanks for the work :heart:

I fully agree, it feels a bit out of place in this dashboard :+1:

[jwcastillo]

Ok I put it in a separate dashboard, like the custom metrics example

Looks awesome!

I think we shouldn't document the dashboards here. It would be better if we update the official doc. I think in this repo we should only document stuff specifically for the extension, all the rest should stay on the k6-docs.

I would open a PR to drop all the current text of the README and structure a list of links plus the specific info for the extension. Similar to what @MattDodsonEnglish did for https://github.com/grafana/k6/blob/master/README.md.

@ppcano @javaducky WDYT?

@codebien If the dashboards are now ready, I suggest merging the PR and we'll update the readme and the docs.
