    Meaning

    The chassisd database provides the date, time, and a component status message. The chassisd database is dynamic. It is initialized at router startup and is updated when components are added or removed. You can search for multiple items in the chassisd log file by using the | match cb command to see error messages that are generated when a Control Board fails or is offline. Use this information to diagnose a Control Board problem and to let JTAC know what error messages were generated and the router events that occurred before and after the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.
