Juniper Networks J-Series manual Displaying Log and Trace Files from the CLI

J-series™ Services Router Administration Guide

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-sourcecommand 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-logcommand 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.
