Configuring the event source server

The rsyslog service is used to transmit events from the server to the KUMA collector.

To configure transmission of events from the server to the collector:

1. Make sure that the rsyslog service is installed on the event source server. For this purpose, execute the following command:

   systemctl status rsyslog.service

   If the rsyslog service is not installed on the server, install it by executing the following command:

   yum install rsyslog

   systemctl enable rsyslog.service

   systemctl start rsyslog.service

2. Edit the audit.service configuration file, /etc/audit/auditd.conf, and change the values of the following parameters:

   name_format=NONE

   log_format=ENRICHED

   The log_format parameter determines the format of the records generated by the auditd service, and must be set to ENRICHED to have user information saved in events.

   After editing the settings, restart the auditd service:

   sudo systemctl restart auditd.service

3. In the /etc/rsyslog.d directory, create the audit.conf file with the following content, depending on your protocol:
   • To send events over TCP:

     $ModLoad imfile

     $InputFileName /var/log/audit/audit.log

     $InputFileTag tag_audit_log:

     $InputFileStateFile audit_log

     $InputFileSeverity info

     $InputFileFacility local6

     $InputRunFileMonitor

     *.* @@<IP address of the KUMA collector>:<port of the KUMA collector>

     For example:

     *.* @@192.1.3.4:5858

   • To send events over UDP:

     $ModLoad imfile

     $InputFileName /var/log/audit/audit.log

     $InputFileTag tag_audit_log:

     $InputFileStateFile audit_log

     $InputFileSeverity info

     $InputFileFacility local6

     $InputRunFileMonitor

     template(name="AuditFormat" type="string" string="<%PRI%>%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag% %msg%\n")

     *.* @<IP address of the KUMA collector>:<port of the KUMA collector>

     For example:

     *.* @192.1.3.4:5858;AuditFormat

4. Save the changes to the audit.conf file.
5. Restart the rsyslog service by executing the following command:

   systemctl restart rsyslog.service

The event source server is configured. Data about events is transmitted from the server to the KUMA collector.
