Environment

• Red Hat Enterprise Linux 7

Issue

• On my RHEL7 newely installed system I am seeing the following in /var/log/messages all the time

  Raw

  
  Jul 24 08:50:01 example.com systemd: Created slice user-0.slice.
  Jul 24 08:50:01 example.com systemd: Starting Session 150 of user root.
  Jul 24 08:50:01 example.com systemd: Started Session 150 of user root.
  Jul 24 09:00:01 example.com systemd: Created slice user-0.slice.
  Jul 24 09:00:02 example.com systemd: Starting Session 151 of user root.
  Jul 24 09:00:02 example.com systemd: Started Session 151 of user root.
  
  

Resolution

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

• To suppress these log entries in /var/log/messages, create a discard filter with rsyslog, e.g., run the following command:

  Raw

  
  echo 'if $programname == "systemd" and ($msg contains "Starting Session" or $msg contains "Started Session" or $msg contains "Created slice" or $msg contains "Starting user-") then stop' >/etc/rsyslog.d/ignore-systemd-session-slice.conf
  
  

  Then restart the rsyslog service

  Raw

  
  systemctl restart rsyslog
