Category: Administration

Learn how to use and maintain NTA in your environment.

How does default DNS resolution work in SolarWinds NTA In SolarWinds NTA, host or domain names are stored directly in individual flows. SolarWinds NTA receives a flow from an IP address and waits for the DNS server to resolve it.
NTA settings You can use SolarWinds NTA to customize monitoring flow traffic and CBQoS data on your network to provide the most relevant information.
NTA port requirements This resource lists ports that SolarWinds NetFlow Traffic Analyzer uses to communicate with other devices and servers.
Monitor bandwidth utilization using Flow Navigator filters Use the Flow Navigator application to filter your SolarWinds NTA views and add them directly to the Views toolbar.
DNS resolution options To meet your specific network monitoring needs, SolarWinds NTA provides the different options for configuring a DNS resolution.
View NTA data in the Orion Web Console After you configure and enable a NetFlow source, you can view the various types of NetFlow statistics that it records in the Orion Web Console. The statistics are provided as resources grouped to form individual views.
NTA - Understanding NetFlow Bandwidth Traffic IN and Traffic OUT display Understand NetFlow Bandwidth Traffic IN and Traffic OUT display.
Enable monitoring on unmonitored traffic in NTA This resource describes how to monitor unmonitored traffic in NTA.
Unmanaged NetFlow interface This resource provides information when SolarWinds NTA is receiving traffic from an interface which is not managed in SolarWinds NPM. However, the corresponding node is managed in SolarWinds NPM.
Enable monitoring on unmonitored traffic in NTA This resource describes how to monitor unmonitored traffic in NTA.
NTA charts SolarWinds NTA charts display pie chart or area chart summaries of resource-related data, enabling a more detailed view of resources. You can create different types of area charts, including stack area, stack spline area, stack line, line, spline, and bar.
NTA reports In SolarWinds NTA, flow data are stored in the NTA Flow Storage Database and CBQoS data are stored in the SolarWinds Orion database. Over time, both databases accumulate a large amount of information. SolarWinds offers both a broad array of predefined reports and user interfaces that enable you to create your own custom reports.
NetFlow collector services NetFlow Collector Services provides status information about current flow collectors. In case your flow-enabled device configuration requires it, the following procedure resets or adds flow collection ports on which the SolarWinds NTA collector listens for flow data.
CBQoS policies SolarWinds NTA offers flow traffic statistics that can help in determining what CBQoS classes and policies to create and apply. SolarWinds NTA also includes configurable alerts to help you verify the expected effects of the policy maps you apply to interfaces on your relevant Cisco devices. SolarWinds NTA provides information for tuning the CBQoS implementation.
Ingress bytes, egress bytes, bytes through, and total bytes in NTA This resource discusses the difference between ingress bytes, egress bytes, bytes through, and total bytes in NTA.
Configure NTA-specific alerts

You can use the out-of-the-box alerts as templates for customized alerts. Configure an alert for SolarWinds NTA based on a predefined top talker or CBQoS alert.

Bandwidth capacity planning and analysis Use SolarWinds NTA to monitor interface-level network bandwidth and traffic patterns over the course of months, days, or minutes. SolarWinds NTA converts flow data into charts and tables that quantify exactly how a network is being used, by whom, and for what purpose.
Find the cause of high bandwidth utilization If a node managed in SolarWinds NPM is also a NetFlow source, it exports NetFlow data that you are currently monitoring in SolarWinds NTA. You can use SolarWinds NTA to analyze interface bandwidth utilization on the node whenever your workflow requires.
