    Gather Component Alarm Information

    When you obtain information about component alarms and error messages, you determine when a problem with a component first appeared and the details of the situation.

    To gather component alarm information:

    1. Display the Current Router Alarms
    2. Display Error Messages in the Messages Log File
    3. Display Error Messages in the Chassis Daemon Log File

    Display the Current Router Alarms

    Purpose

    To determine the details of the alarms and when they first appeared in the component.

    Action

    To display the current router component alarms, use the following command:

    user@host> show chassis alarms

    The command output displays the number of alarms currently active, the time when the alarm began, the severity level, and an alarm description. Note the date and time of an alarm so that you can correlate it with error messages in the messages system log file.

    Various conditions related to the chassis components trigger yellow and red alarms. You cannot configure these conditions. Table 1 through Table 9 list the alarms that the chassis components can generate.

    Table 1 lists the alarms that the chassis components can generate on an M5 or M10 router.

    Table 1: M5 or M10 Router Chassis Component Alarm Conditions

    Chassis Component

    Alarm Condition

    Remedy

    Alarm Severity

    Alternative media

    The router boots from alternate boot device: the hard disk. Typically, the router boots from the flash drive. If you configure your router to boot from the hard disk, ignore this alarm condition.

    Display Error Messages in the Messages Log File

    Purpose

    To determine the details of the error messages in the Messages Log File.

    Action

    To display router component error messages in the messages system log file, use the following command:

    user@host> show log messages

    The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. Display the error messages in the messages system log file logged at least 5 minutes before and after the alarm event.

    To search for specific information in the log file, use the | match component-name command; for example, use 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 messages file in real time, use the monitor start messages command. This command displays the new entries in the file until you stop monitoring by using the monitor stop messages command.

    For more information about system log messages, see the Junos OS System Log Messages Reference.

    Display Error Messages in the Chassis Daemon Log File

    Purpose

    To determine the details of the error messages in the Chassis Daemon Log File.

    Action

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

    user@host> show log chassisd

    The chassis daemon (chassisd) log file keeps track of the state of each chassis component.

    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 command. This command displays the new entries in the file until you stop monitoring by using the monitor stop chassisd command.
