View 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.

The system generates a trace message for each executed command. No password information is saved to the file.

NOTE

The timestamps display format of the show command history output changes based on the service timestamps log datetime configuration. The time format can be in uptime, local time zone time or UTC time.

If timestamp is disabled (no service timestamps log) then command history time format is shown with timestamp defaults (service timestamps log datetime localtime).

To view the command-history trace, use the show command-history command.

Example of the show command-history Command
