openQA Project - coordination #92323: [saga][epic] Scale up: Fine-grained control over use and removal of results, assets, test data
Use external videoencoder in production on all osd machines size:M
Added by okurz over 3 years ago.
Updated about 1 year ago.
Description
Motivation¶
See #68923
Acceptance criteria¶
- AC1: All osd workers run the same external video encoder configured (exceptions allowed if required and documented) as in #77839
- AC2: All osd workers are not overstressed by the external video encoder, i.e. not more jobs failing or incompleting due to an overstressed worker
Suggestions¶
- Research what has been done in #77839 and #77842
- Ensure ffmpeg is installed on all worker machines with salt
- Configure external video encoder as documented in #68923#note-17 but with salt
- Do a step-wise roll-out, e.g. based on salt roles
- Monitor the CPU usage of ffmpeg e.g. via
htop and also the overall performance of each worker, e.g. check for incomplete jobs due to performance issues
- Wait for feedback for some days

On OSD in /var/lib/openqa/testresults I called timeout 600 nice ionice -c 3 find -name '*.webm' and found an endless list of videos so seems workers. I was also checking the load of worker13 as an example and found no significant difference in the periods of ogv or webm/VP9 encoding. So both ACs covered, we are good.
