[Letsencrypt-devel] Bug#873581: certbot: Excessive logging

[Henrik Ahlgren]

Package: certbot
Version: 0.10.2-1~bpo8+1
Severity: normal

Certbog logs to /var/log/letsencrypt.log using DEBUG as the default
log level. It rotates the log on each invocation, i.e. (at least)
daily. If I understand correctly (main.py:setup_log_file_handler),
1000 log files are retained.

On my server, I have hundreds of small log files:

# ls /var/log/letsencrypt|wc -l
597

Most of the debug information contained in the logs are not very
useful for sysadmins and it is quite difficult to find any relevant
information about certificate renewals etc.

Please consider making the log level configurable and make the default
"info". Also it would be nice, if logrotate would handle log rotation,
so the sysadmin could easily modify the rotation behaviour. Better
yet, the possibility of logging directly into systemd journal would be
great.
