100,000 hosts each report 200 metrics every 10 seconds. How many data points per second does the ingestion tier receive?

Answer

About 2,000,000 data points/s. In review, anything from 1,000,000 to 4,000,000 counts as right.

The worked estimate

Per host: 200 ÷ 10 s = 20 points/s. × 100,000 hosts = 2,000,000 points/s. At that rate, pre-aggregating before storage cuts the write volume a lot.

Numbers: Numbers to know.
