Antoine "hashar" Musso <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Priority|Normal |High --- Comment #5 from Antoine "hashar" Musso <[email protected]> --- There is another issue that have triggered a few time this week which is that updating the job description is suddenly slow. Ganglia shows a CPU at 100%, top -i then H shows a jenkins thread at 100% Looking at the apache proxy that handles Jenkins access, one can monitor what Zuul is doing with Jenkins: tail -f /var/log/apache2/integration_access.log|grep Python-urllib It shows Zuul update the build descriptions with requests such as: POST /ci/job/mediawiki-core-qunit/3359/submitDescription 302 GET /ci/job/mediawiki-core-qunit/3359/ 200 They take from 3 to 12 seconds and even more sometime. That is the root cause of slowness. Whenever a build is started or emit a result, Zuul will update the description of all the builds that have been triggered by that change. So given a pipeline of 10 jobs, that is potentially a lot of description update. Zuul is also locked waiting for Jenkins to answer which in turns make it very slow to process events. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
