FYI they also have a nice public Grafana instance at https://grafana.wikimedia.org https://grafana.wikimedia.org
It has all the info about HTTP requests, DB info, CDN, etc.
The wiki page about this https://wikitech.wikimedia.org/wiki/Grafana https://wikitech.wikimedia.org/wiki/Grafana
- yread 4y agoInteresting. I kinda expected more traffic. 20 edits/s, 100k request/s. One tuned box could handle that
- bdsa 4y agoNot sure about the edits, but the title of the requests graph including "Varnish frontend CDN" and the query ("job_method_status:varnish_requests...") imply to me that those are the requests from a frontend cache (Varnish) or series of caches to the backend, rather than all requests. (I'm not 100% sure you intended to suggest Wikipedia only gets 100k requests/s, I just thought it was an interesting discussion point.)
- Philip-J-Fry 4y agoBased on all the monitoring I've ever seen, the stats for Varnish would be the requests into Varnish. If you wanted actual requests into the app servers you would look at those stats, and from that site, it's like ~5k req/s. https://grafana.wikimedia.org/d/RIA1lzDZk/application-servers-red?orgId=1 https://grafana.wikimedia.org/d/RIA1lzDZk/application-server... I'm not sure why you think 100k req/s is low for Wikipedia
