NetFlow Monitoring

I already have OpManager. Why do I need the NetFlow add-on?

OpManager helps you to monitor health, availability, and performance of all devices and applications on your network. The NetFlow add-on provides detailed information on network bandwidth usage with drill-down into specific applications, users, ports and conversations. This helps in determining the exact reason for bandwidth spikes and outages. The store of flow information thus collected also helps in important capacity planning decisions. The combination of OpManager & NetFlow Add-on serves as a powerful and extensive network monitoring solution for your enterprise.

Which devices are supported by the NetFlow add-on?

The NetFlow Add-on leverages NetFlow^®, sFlow^®, IPFIX^® cflowd^®, J-Flow^®, rFlow^®, NetStream^® and Cisco NBAR^® information exported from routing - switching devices to provide in depth visibility into the top talkers and applications on your network.
