Test 075 for Alex Valdez

Request

Inspect metrics-router-history#37 and review its account of the March 29, 2023 OTel collector tuning.

Required memory

Fact 18

On March 29, 2023, Alex Valdez and Cyrus spent about an hour investigating the metrics-router OTel collector, whose batch window was still too long under heavier traffic bursts and was causing the memory-spike artifact to recur.

ok so last week's thing wasn't actually fixed. the OTel collector batch window on metrics-router was still holding too long and making that memory-spike artifact show up again under the uglier bursts. Cyrus sat with me on it for about an hour today, Mar 29, and we just pushed the flush interval down from 2s to 1.2s. feels better already in the traces + resident set, but i'm gonna let it run a bit before i call it done -- the old setting looked fine until it didn't.

Fact 20

The metrics-router traces and resident set looked better after the flush-interval change, but Alex Valdez planned to let it run longer before declaring the issue resolved because the previous setting had initially appeared healthy.
