Creating a NetFlow collector or NetFlow Trending collector
Revised: 2018-01-26
There are two types of NetFlow collectors in Observer. Choose the correct one for your needs, or create two different probe instances—one for the NetFlow collector and another for the NetFlow Trending collector.
Prerequisite: Expert Probe
Note: If you want to have scheduled collection of your NetFlow devices, use the settings on the Schedule tab.
NetFlow and sFlow collectors support the following versions of these technologies:
NetFlow: 1, 5, 7, 9, and 10 (IPFIX)
sFlow: 2, 4, and 5
There are two types of NetFlow collectors in Observer. Choose the correct one for your needs, or create two different probe instances—one for the NetFlow collector and another for the NetFlow Trending collector. In most cases, it will likely be the NetFlow Trending collector. The NetFlow Trending collector supports up to 50 NetFlow devices, whereas the NetFlow collector only supports one NetFlow device. That means you must add and configure a NetFlow collector for each NetFlow device in your environment.
