Description

https://grafana.wikimedia.org/d/Pukjw6cWk/thumbor?orgId=1&from=1726768100000&to=1728090927000

scroll to the bottom, open "related graphs".

there were sustained ThumbnailRender requests, pretty consistent volume from 2024-09-20 18:18 until 2024-10-04 01:07. (UTC)

what's going on here? was something maxing out a throttle?

I don't see a corresponding change in response codes: https://grafana.wikimedia.org/d/Pukjw6cWk/thumbor?orgId=1&from=1726768100000&to=1728090927000&viewPanel=62

High ThumbnailRender volume is normal, this is a constant background process that is ongoing to generate thumbnails on newly uploaded files. The change in the graphs from eqiad to codfw is part of the datacentre switchover (T370962).
