Juniper Networks J-Series - Manual (Page 266)

This example displays only mtrace queries. When the Services Router captures an
mtrace response, the display is similar, but the complete mtrace response is also
displayed—exactly as it is displayed in mtrace from-source command output.
Table 126 on page 244 summarizes the output fields of the display.

Displaying Log and Trace Files from the CLI
You can enter the monitor start command to display real-time additions to system
logs and trace files:
user@host> monitor start filename
When the Services Router adds a record to the file specified by filename , the record
is displayed on the screen. For example, if you have configured a system log file
named
system-log (by including the syslog statement at the [ edit system ] hierarchy
level), you can enter the monitor start system-log command to display the records
added to the system log.
To display a list of files that are being monitored, enter the monitor list command.
To stop the display of records for a specified file, enter the monitor stop filename
command.
