good idea to schedule reports to be run at non-peak traffic hours since
generation of reports is a resource hungry process especially for large
A Scheduler is configured to set the parameters for automating
the generation of reports. The parameters to be set for creating a
- Source - The Interfaces or IP Groups which are the
source of traffic.
