Changing the interval shows less green bars in the page

[angoca]

I am using this project here https://github.com/OSMLatam/status and https://status.osm.lat/, and we configured each 15 minutes, instead of hourly.

We configured 5 months ago, but it only shows like las 20 days.

As part of the documentation, it has to explain that when changing the monitoring interval, the tail on the health check should be proportional, and not changed from 2000. https://github.com/OSMLatam/status/blob/2b3aaa84fe71af3f79980c9d49a95a8a1bbd951a/scripts/health-check.sh#L54

For example, for each 15 minutes, it should be changed to 8640, I think.
