Viewing System Log Messages

By default, the View Events page displays the most recent 25 events, with severity levels highlighted in different colors. After you specify the filters, Event Summary displays the events matching the specified filters. Click First, Next, Prev, and Last links to navigate through messages. Table 189 describes the Event Summary fields.

Table 189: Viewing System Log Messages



Additional Information


Displays the time at which the message was logged.



Displays the name and ID of the process that generated the system log message.

The information displayed in this field is different for messages generated on the local Routing Engine or on another Routing Engine (on a system with two Routing Engines installed and operational). Messages from the other Routing Engine also include the identifiers re0 and re1 to identify the routing engine.

For more information, see the JUNOS System Log Messages Reference.

Event ID

Displays a code that uniquely identifies the message.

The prefix on each code identifies the message source, and the rest of the code indicates the specific event or error.

Displays context-sensitive help that provides more information about the event:

  • Help—Short description of the message.
  • Description—More detailed explanation of the message.
  • Type—Category to which the message belongs.
  • Severity—Level of severity.

The event ID begins with a prefix that indicates the generating software process.

Some processes do not use codes. This field might be blank in a message generated from such a process.

An Event can belong to one of the following Type categories:

  • Error—Indicates an error or failure condition that might require corrective action.
  • Event—Indicates a condition or occurrence that does not generally require corrective action.

Event Description

Displays a more detailed explanation of the message.



Severity level of a message is indicated by different colors.

  • Unknown—Gray—Indicates no severity level is specified.
  • Debug/Info/Notice—Green— Indicates conditions that are not errors but are of interest or might warrant special handling.
  • Warning—Yellow—Indicates conditions that warrant monitoring.
  • Error—Blue— Indicates standard error conditions that generally have less serious consequences than errors in the emergency, alert, and critical levels.
  • Critical—Pink—Indicates critical conditions, such as hard drive errors.
  • Alert—Orange—Indicates conditions that require immediate correction, such as a corrupted system database.
  • Emergency—Red—Indicates system panic or other conditions that cause the routing platform to stop functioning.

A severity level indicates how seriously the triggering event affects routing platform functions. When you configure a location for logging a facility, you also specify a severity level for the facility. Only messages from the facility that are rated at that level or higher are logged to the specified file.
