Monitor the overall status of the router by creating a general operation script
that periodically checks network warning parameters, such as high CPU usage.
The general operation script can be overridden by user-defined scripts.
Customize the output of CLI operational mode commands using
If there is a known problem in the JUNOS software, an operation script can
