The service has an endpoint with whole metrics we collect. That is an enormously huge JSON file, that one can fetch from an HTTP endpoint.
There is too much data event to feed some Grafana solution. So we need to filter/normalize the data first.
I use amazing jq. Great tool to update/fetch/patch/present data. On macOS
you may simply say
brew install jq to have it.
Fetching data in the console can be done simply too. I use curl for that.

That is the snipped I finally did
I’m happy I came across several amazing tools, and it turned to be easy and fun to generate some analytics ‘reports’ like that:
I use Marvell character names instead of real names :)comments powered by Disqus
