CHAPTER 40 Syslog 40.1 Syslog Overview This chapter explains the syslog screens. The syslog protocol allows devices to send event notification messages across an IP network to syslog servers that collect the event messages. A syslog-enabled device can generate a syslog message and send it to a syslog server. Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related information of syslog messages. Each syslog message has a facility and severity level. The syslog facility identifies a file in the syslog server. Refer to the documentation of your syslog program for details. The following table describes the syslog severity levels. Table 163 Syslog Severity Levels CODE SEVERITY 0 Emergency: The system is unusable. 1 Alert: Action must be taken immediately. 2 Critical: The system condition is critical. 3 Error: There is an error condition on the system. 4 Warning: There is a warning condition on the system. 5 Notice: There is a normal but significant condition on the system. 6 Informational: The syslog contains an informational message. 7 Debug: The message is intended for debug-level purposes. 40.1.1 What You Can Do • Use the Syslog Setup screen (Section 40.2 on page 328) to configure the device's system logging settings. • Use the Syslog Server Setup screen (Section 40.3 on page 329) to configure a list of external syslog servers. 40.2 Syslog Setup Use this screen to configure the device's system logging settings. Click Management > Syslog in the navigation panel to display this screen. The syslog feature sends logs to an external syslog server. GS1920 Series User's Guide 328
