Meaning The messages system log file records the time the failure or event occurred, the severity
level, a code, and a message description. You can use the date and time to browse the
messages log file, or you can use the show log messages | match component-name
command to view error messages that are specific to a particular component. For
example, the command output shows the common power supply error messages logged
from the router. In the filter expression, if there is a space in the component name, enclose
the component name in quotation marks, for example | match “ power supply”.
Use system log file information to isolate a component problem and to let the Juniper
Networks Technical Assistance Center (JTAC) know what error messages were generated
at the time of the event. For more information about system log messages, see the Junos
OS System Log Messages Reference.
