(config add network analyzer name)> on_interval value
(config add network analyzer name)>
where value is any number of weeks, days, hours, minutes, or seconds, and takes
the format number{w|d|h|m|s}.
For example, to set on_interval to ten minutes, enter either 10m or 600s:
(config network analyzer name)> on_interval
(config network analyzer name)>
set_time: Runs the script at a specified time of the day. If set_time is set, set the
time that the script should run, using the format HH:MM:
(config network analyzer name)> run_time HH:MM
