This seems to be related to NFS, or maybe some interaction between docker and NFS.
I set up django to do its own logging, and saw the same behavior. Next I connected to the docker node with "webservice --backend=kubernetes python3.7 shell" and append directly to the log file with "echo foo >> django.log". It still took 30 seconds or so to show up while I was tailing the file on the bastion.

My guess is output stream buffering, at either the libc level or the python level.
Which tool is this? I can probably strace and see if that is the case.

I'm running a web server with "webservice --backend=kubernetes python3.7". As I tail the uwsgi.log file, requests to my server get logged with very long delays. I just timed one at about a minute and a half between when the request was served (03:07:57 UTC 2020) and when it showed up in the log file (03:09:23 UTC 2020).
What is going on here? Is there some way to make it not do this? _______________________________________________ Wikimedia Cloud Services mailing list Cloud@lists.wikimedia.org (formerly labs-l@lists.wikimedia.org) https://lists.wikimedia.org/mailman/listinfo/cloud
