Displaying Real-Time Log Messages

You can configure the system to maintain a running real-time display of log messages on the console
display or on a (telnet) session. To turn on the log display on the console, use the
console-display
option in the following command:
enable log target [console-display | memory-buffer | nvram | session | syslog [<host
name/ip> {:<udp-port>} [local0 ... local7]]]
This setting may be saved to the FLASH configuration and will be restored on boot up (to the
console-display session).
To turn on log display for the current session:
enable log target session
This setting only affects the current session, and is lost when you log off the session.
The messages that are displayed depend on the configuration and format of the target. See the section,
"Filtering Events Sent to Targets", for information on message filtering, and the section, "Formatting
Event Messages", for information on message formatting.

Displaying Events Logs

The log stored in the memory buffer and the NVRAM can be displayed on the current session (either
the console display or telnet). Use the following command to display the log:
show log {messages [memory-buffer | nvram]} {severity <severity> {only}}
{starting [date <date> time <time> | date <date> | time <time>]} {ending [date
<date> time <time> | date <date> | time <time>]} {match <match-expression>}
{format <format>} {chronological}
There are many options you can use to select the log entries of interest. You can select to display only
those messages that conform to the specified:
• severity
• starting and ending date and time
• match expression
The displayed messages can be formatted differently from the format configured for the targets, and
you can choose to display the messages in order of newest to oldest, or in chronological order (oldest to
newest).
