Separate vassal logging with uWSGI emperor mode

Question

I'm running uWSGI 1.9.17 in emperor mode (with the default config from Trusty's uwsgi-emperor package), and the emperor's logs are piping into /var/log/uwsgi/emperor.log.

The emperor.log file also contains all the stdout/err combined from each vassal, and I can't seem to get any of the vassals to log to a separate file. I've tried using the logto = /var/uwsgi/apps/vassal1.log config options but to no avail.

Does anyone have any idea how to get the vassals logging to separate files?

Answer 1

To separate vassal logs from emperor, you can use logger:

logger = file:/var/uwsgi/apps/vassal1.log

I'm not sure why logto doesn't work on vassals, but loggers works fine. You can even specify what should be logged to what file (or by using other plugins, not only to file). More on loggers you can find here
