 5-Notice: normal but significant condition  6-Informational: informational messages  7-Debug: debug-level messages When a syslog server has been defined, messages matching the rules defined here are sent to the syslog server. The syslog protocol uses UDP port 514. Log Rotation: Configuring Data Retention To configure the number of weeks to retain records for data, log files, disabled accounts, and mobile device certificates, click the Configure data retention link in Log Rotation row. The Data Retention Policy page opens. Log files are rotated and expired logs are cleared according to the database maintenance schedule you define. See Managing Data Retention. Log Collector: Storing Incoming Syslog Messages Your ClearPass Guest server can also act as a syslog server. To configure the ClearPass Guest server to receive syslog messages sent by remote hosts in the network, mark the check box in the Log Collector row. The Allowed Access row is added. You can specify IP addresses and networks from which messages may be received, or allow syslog messages to be received from any IP address. Storing incoming syslog messages can use a lot of disk space. If you choose the log collector option, be sure to set appropriate data retention limits and enable low disk space notifications. 402 | Administrator Tasks ClearPass Guest 3.9 | Deployment Guide
