How to increase the log level?
When starting ci-daemon, you can increase log verbosity and see logs on standard error output by providing command line arguments:
$ ci-daemon -v2 --alsologtostderr
On a server, this is enabled by default. You can find the logs in systemd journal:
$ journalctl -u ci-server
However, when looking for messages from the software under test, it is recommended to look in docker logs instead, as they are more complete in that regard than ci-daemon logs.
