FS728TP Smart Switch Software Administration Manual The following example shows the standard format for a log message: Mar 24 05:34:05 10.131.12.183-1 UNKN[2176789276]: main_login.c(179) 3855 %% HTTP Session 19 initiated for user admin connected from 10.27.64.122 The number contained in the angle brackets represents the message priority, which is derived from the following values: Priority = (facility value × 8) + severity level. The facility value is usually one, which means it is a user-level message. Therefore, to determine the severity level of the message, subtract eight from the number in the angle brackets. The example log message has a severity level of 6 (informational). For more information about the severity of a log message, see the Severity Filter description on page 208. The message was generated on March 24 at 5:34:05 a.m by the switch with an IP address of 10.131.12.183. The component that generated the message is unknown, but it came from line 179 of the main_login.c file. This is the 3,855th message logged since the switch was last booted. The message indicates that the administrator logged onto the HTTP management interface from a host with an IP address of 10.27.64.122. Use the buttons at the bottom of the page to perform the following actions: • Click Clear to clear the messages out of the buffered log in the memory. • Click Refresh to update the page with the latest messages in the log. • Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. FLASH Log Configuration The FLASH log is a log that is stored in persistent storage, which means that the log messages are retained across a switch reboot. • The first log type is the system startup log. The system startup log stores the first N messages received after system reboot. This log always has the log full operation attribute set to stop on full and can store up to 32 messages. • The second log type is the system operation log. The system operation log stores the last N messages received during system operation. This log always has the log full operation attribute set to overwrite. This log can store up to 1000 messages. Either the system startup log or the system operation log stores a message received by the log subsystem that meets the storage criteria, but not both. On system startup, if the startup log is configured, it stores messages up to its limit. The operation log, if configured, then begins to store the messages. Use the FLASH Log Configuration page to enable or disable persistent logging and to set the severity filter. To access the FLASH Log Configuration page, click the Monitoring  Logs tab, and then click the FLASH Log link. Chapter 6: Monitoring the System | 205
