Based on the hardware configuration of the system, a collector can handle around interfaces. Refer sizing guide for hardware configuration. Central Server can handle any number of collectors. New collectors can be added seamlessly at anytime. Collector communicates through the https port of Central Server. SNMP parameters like read community, port can be configured while installing the collector.
If you want to change after installing the collector, you can do so from a collector web client. Collector will hold the data and sends them once connection is re-established. Thus collector ensures reliable data transfer. Collector contacts Central Server for two purposes. The frequency to send NetFlow data is 10 minutes and the frequency to get the configuration is one minute. Collector sends the data through secure https connection.
We have bundled SSL certificates generated using Java's keytool. If you like to change the certificates, you can use the sslgen. You can view the actual bandwidth used for data transfer from the "Collector Details" page in the Central Server's web client. You can find the link to this page under Admin Operations.
The Collector Dashboard view shows the top 10 interfaces in each collector by default. To customize it, please use the "Customize" link beside the Dashboard link. If the collector is behind a proxy, then enter the proxy settings either in Collector's Installation screen or in the Settings page in web client. The licensing is based on the flow rate.
