The Memory Log table displays on the Memory Log page.
The Total number of Messages field displays the number of messages the system logged
in memory. Only the 200 most recent entries are displayed on the page.
The rest of the page 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 support 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 1, which means it is a user-level message. Therefore, to
determine the severity level of the message, subtract 8 from the number in the angle
brackets. The sample log message shows a severity level of 6 (informational). For more
information about the severity of a log message, see
Manage the server log on
page 412.
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 on to the
HTTP local browser interface from a host with an IP address of 10.27.64.122.

Message log format
This topic applies to the format of all logged messages that are displayed for the message
log, persistent log, or console log.
Messages logged to a collector or relay through syslog use an identical format:
• <15>Aug 24 05:34:05 0.0.0.0-1 MSTP[2110]: mspt_api.c(318) 237%%
Interface 12 transitioned to root state on message age timer
expiry.
This example indicates a message with severity 7 (15 mod 8) (debug) on a chassis and
generated by component MSTP running in thread ID 2110 on Aug 24 05:34:05 by line
318 of file mstp_api.c. This is the 237th message logged with system IP 0.0.0.0 and
task-ID 1.
