feat: decrease pgbouncer client con SLO to 85% (!4873) · Merge requests · GitLab.com / Runbooks · GitLab

Steve Xuereb requested to merge feat/decrease-saturation-slo into master Aug 05, 2022

What

Bring back the original 85% hard SLO, and 80% soft SLO

Why

We were reaching the max_client_conn saturation SLO from time to time until we addressed this in https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/16121#note_1051842221 we increased the SLO to stop paging the on-call.

As we can see in https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/16121#note_1051842221 the saturation was fixed so we can decrease the SLO once more.
