Step 3: Display Error Messages in the Chassis Process Log File

Action

To display router component errors in the chassis process (chassisd) system log file, use the following CLI command:

user@host> show log chassisd

The chassis process (chassisd) log file tracks the state of each chassis component. For examples of sample output, see the JUNOS System Basics and Services Command Reference.

To search for specific information in the log file, use the | match component-name command; for example, show log messages | match fpc. If there is a space in the component name, enclose the component name in quotation marks; for example, | match "power supply".

To search for multiple items in the log file, use the | match command followed by the multiple items, separated by the | (pipe), and enclosed in quotation marks; for example, | match "fpc | sfm | kernel | tnp".

To monitor the chassisd file in real time, use the monitor start chassisd CLI command. This command displays the new entries in the file until you stop monitoring by using the monitor stop chassisd CLI command.
