To make the best use of SolarWinds NTA, use the following guidelines to make decisions about where to capture enabled flow data.

If your devices are configured to export NetFlow on both ingress and egress interfaces, you might see duplicate traffic in the Summary resources.

Retention period specifies the time for which flow data are stored in the database until they expire and are permanently deleted. The default retention period is set to 30 days. You should then have an idea of the volume of data your network produces with NetFlow enabled. Consider also the space taken up by the database, and then adjust the retention period accordingly.

Documentation for NetFlow Traffic Analyzer. Flow environment best practices This section provides recommendations for setting your flow environment.

Understand your network and identify the types of problems you want to solve by capturing flow data. If you need more flow data, move to the distribution layer. Due to the proliferation of duplicate data, SolarWinds recommends that you do not enable flows at the access layer. If you want to monitor internal traffic and internet traffic, enable ingress and egress interfaces. To capture the entire network conversation, enable ingress and egress on the external interfaces of a single node, or enable ingress only on all interfaces on the node.

Be mindful of directionality and duplication If your devices are configured to export NetFlow on both ingress and egress interfaces, you might see duplicate traffic in the Summary resources. Duplicate flows can occur in the following cases: You have both ip flow ingress and ip flow egress applied for all interfaces on a device.

You have set ip flow ingress on some interfaces and ip flow egress on other interfaces. On your serial interfaces with subinterfaces, you have NetFlow export enabled on both the physical and logical interfaces. Set the retention period Retention period specifies the time for which flow data are stored in the database until they expire and are permanently deleted.

Network bandwidth management is a vital activity for every network engineer. With NTA, you're just clicks away from being able to create, schedule, and deliver in-depth network traffic and bandwidth reports. NetFlow analyzer and monitoring converts that data into easy-to-interpret charts and tables, which quantify exactly how the network is being used, by whom, and for what purpose.

Identifying which users, applications, protocols, or IP address groups are consuming the most bandwidth is an essential part of delivering better quality service. A NetFlow analyzer can be implemented in networks of all sizes where the network professional would like insight into bandwidth usage.

NetFlow analysis can be programmed over the course of months, days, or minutes, allowing you to gather long-term and short-term sets of data. Developed by network and systems engineers who know what it takes to manage today's dynamic IT environments, SolarWinds has a deep connection to the IT community.
