The Memory Log table displays on the Memory Log screen.
The Total Number of messages displays the number of messages the system has logged in
memory. Only the 200 most recent entries are displayed on the screen.
The rest of the screen displays the Memory Log messages. The format of the log message is
the same for messages that are displayed for the message log, persistent log, or console log.
Messages logged to a collector or relay through syslog have the same format as well.
The following example shows the standard format for a log message:
<14> 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
Server Log on page 330.
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 3,855
th
message logged since the switch was last
booted. The message indicates that the administrator logged on to the HTTP management
interface from a host with an IP address of 10.27.64.122.
Use the buttons at the bottom of the screen to perform the following actions:
• Click the Clear button to clear the messages out of the buffered log in the memory.
• Click the Refresh button to refresh the page with the latest information on the switch.
• Click the Cancel button to cancel the configuration on the screen and reset the data on
the screen to the latest value of the switch.
FLASH Log
The FLASH log stores log messages in persistent storage, which means that the log
messages can be retained across a switch reboot. The FLASH log can display the current
operational and startup log messages, or it can display up to 64 messages that were logged
