Set up percentage monitor/trigger


Can someone please explain, how Open Distro is supposed to be used to set up monitors for relative/percentage triggers?

I ingest around 10Mio/15Mio documents / day to elastic
In kibana Id like to set up an Open Distro alert that triggers if 15% of previous days documents (10/15Mio. * 0.15%) return a 5xx status code?
as a first hurdle I seem to get max 10000 results returned. Im not sure how to bypass that either.

Any help would be appreciated
