Monitoring Logging System Events

Use the show log configuration command to display your log configuration. Use the show log data command to display system events on your screen.

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See show Commands in Chapter 2, Command Line Interface, for details.

    show log configuration

• Use to show the logging configuration on your system.
• Example 1 - factory defaults are set

host1#show log configuration

  log destination console severity WARNING

  log destination nv-file severity CRITICAL

  no log engineering

    show log data

• Use to display system events. The following keywords allow you to be selective about which events are displayed.
• category - limits the display to a single log event category. Refer to the CLI online Help for available categories.

• Example

host1#show log data category os

• delta - limits the display to events that occurred after the time set with the log baseline command.
• nv-file - displays the information that is currently logged to nonvolatile storage.

• Example

host1#show log data nv-file

logFile.temp: The system cannot find the file specified.
