What system do you use to store server logs?
 Is it Zabbix, PRTG, Kiwi, or some other system?

Zabbix has excellent compatibility with Grafana UI.

Yes,   zabbix is flexible in terms of adding custom things. therefore, I use it can be adapted to any requirements of both the security department and the technical support department

If you are the sole manager of your server, receiving notifications about successful authorizations may not be necessary. However, if multiple users have access, you can set up checks for specific individuals or all users.

The setup will employ the standard functionality of Zabbix, and no configuration is needed on the hosts except granting read permission for the log file to the Zabbix group. This may require relaxing some local security policies since the system log is usually only readable by root. In CentOS, you can fix this issue as follows:

# chgrp zabbix /var/log/secure
# chmod 640 /var/log/secure
and the same in Debian/Ubuntu

# chgrp zabbix /var/log/auth.log
# chmod 640 /var/log/auth.log
All is ready on the host.
