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. By default, up to 160 (80 percent of the maximum of 200) of the
most recent entries can be 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:
<189> Jan 05 2021 00:00:18: AAA-5-CONNECT: New http connection
for user admin, source 192.168.1.111 ACCEPTED
The message was generated as severity 189 (Notice, level 5) on January 5, 2021 at
00:00:18 a.m. by component AAA. The message indicates that the administrator
successfully logged on to the HTTP management interface from a host with IP address
192.168.1.111.
The severity number in the message is generated by a combination of the facility
and the severity. In the previous example, the default facility of 23 is multiplied by
8 and the severity (5) is added: (23 * 8) + 5 = 189
