Logs coming with systemd messages: Created slice & Starting Session

Logs coming with systemd messages: Created slice & Starting Session :-

Normally thiss issue is come Centos/Linux/RHEL7 newely installed system. when i check following in /var/log/messages all the time show.

Aug 23 06:40:20 example.com systemd: Created test user-0.test.
Aug 23 06:40:20 example.com systemd: Starting Session 150 of user root.
Aug 23 06:40:20 example.com systemd: Started Session 150 of user root.
Aug 23 06:40:20 example.com systemd: Created test user-0.test.
Aug 23 06:40:21 example.com systemd: Starting Session 151 of user root.
Aug 23 06:40:22 example.com systemd: Started Session 151 of user root.

Solution :-
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:

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

systemctl restart rsyslog
