Every minute 6 entries.

I stopped this behavior by creating a ignore-systemd-session-slice-sogo.conf file in/etc/rsyslog.d/ with this content:

if $programname == "systemd" and ($msg contains "Starting Session" or $msg contains "Started Session" or $msg contains "Created slice" or $msg contains "Starting User" or $msg contains "Removed slice User" or $msg contains "Stopping User") then stop

(I got this from https://unix.stackexchange.com/questions/267965/system-log-full-of-session-and-slice-messages with little modifications and it works.)

2 questions @stephdl

  1. do we need this messages in the log or are they relevant?
  2. if not, wouldn’t it be convenient to create this file automatically and restart rsyslog when installing SOGo ?

tk I will look

reminder for me: https://access.redhat.com/solutions/1564823

when in the link above I can read

Resolution

These messages are normal and expected -- they will be seen any time a user logs in

Does the solution need to come from sogo, do we need to put a workaround in the wiki page to remove this logs noise, or do sogo must decide for the whole system…I must say I don’t know

… it would be neat to to be able to set the SOGo loglevel to minimal in the GUI and ignore these messages, or have all systemd messages in a sepparate logfile. /var/log/messages on a bussy SOGo server, is useless because of all this slice garbage.

Logo gets its logs, but here it is systemd noise you see. If you don’t want to see them, then you must adjust your /etc/systemd/system.conf

#LogLevel=info
to
LogLevel=notice

or create a rsyslog filter like you see.

The noise comes from this cron

# Email alarms - runs every minutes
# If you need to use SMTP AUTH for outgoing mails, specify credentials to use
# with '-p /path/to/credentialsFile' (same format as the sieve credentials)

I think the “Fine tune SOGo” section in the wiki would be a good place for that.
Those who are disturbed by the noise can find a workaround in the wiki.
