praefect: Backport separate endpoint for datastore collector (v14.5) (!4107) · Merge requests · GitLab.org / gitaly · GitLab

Patrick Steinhardt requested to merge pks-praefect-datastore-collector-metrics-endpoint-v14.5 into 14-5-stable Nov 19, 2021

This MR backports !4085 (merged) and !4092 (merged) to v14.4.

Part of #3920 (closed), #3286 (closed)

Note that !4085 (merged) is already part of v14.5.0, so this really only backports !4092 (merged).
