Recognize a high CPU condition
A high CPU condition exists when any of the messages in Message 10 appear.
Command history
The command-history trace feature captures all commands entered by all users of the system with a time
stamp and writes these messages to a dedicated trace log buffer. When the
show command-history
command is entered, the system displays a trace message for each executed command. No password
information is saved to the file. The trace messages are not saved to a file or directory on the internal
system flash.
To view the command-history trace, use the
show command-history command, as shown in the following
example.
FTOS#show command-history
[6/16 16:22:3]: CMD-(CLI):[enable]by default from console
[6/16 16:22:6]: CMD-(CLI):[show cam-profile]by default from console
[6/16 16:38:9]: CMD-(TEL0):[enable]by admin from vty0 (10.11.48.30)
[6/16 16:38:10]: CMD-(CLI):[show qos statistics]by default from console
[6/16 16:38:21]: CMD-(TEL0):[show command-history]by admin from vty0 (10.11.48.30)
Clearing the command history
Clear the command history buffer using the command clear command-history from EXEC Privilege mode,
as shown in the example below.
