The SolarWinds NetFlow Website Traffic Analyzer (NTA) could well be called the Network Traffic Analyzer considering that it handles not simply the initial Cisco NetFlow but much of its variations from various other producers, as well as NetFlow’ s main choice, sFlow.(That s why we covered NTA in our evaluation of sFlow collection agencies as well as analyzers.)

SolarWinds NTA is not a standalone tool, however rather a component that can be contributed to SolarWinds’ Network Efficiency Display(NPM). The mix of these 2 modules create a full network checking software package. NTA as well as NPM incorporate with the remainder of SolarWinds’ Orion platform devices, such as the Network Configuration Manager.

NTA gathers interface-level circulation data and Cisco Class-Based High Quality of Service (CBQoS) data, combining them with performance data that NPM gathers from SNMP, WMI, and also various other sources. It refines the data to produce interactive charts and also personalized records, giving you “& ldquo; one pane of glass” & rdquo; visibility into your network’ s standing and its historic actions. NPM as well as NTA offer you a vast array of innovative centers for managing multi-vendor networks: transmission capacity tracking, web traffic analysis, efficiency analysis, informs, personalized records, policy optimization, etc. NTA and also NPM are readily available in a 30-day fully-functional test, and pricing relies on the number of network aspects you’ ll be checking

A transmission capacity screen as well as traffic analyzer primarily assists you to spot and also troubleshoot network troubles, and also to identify traffic patterns and patterns so you can adjust policies and plan network modifications.

What are NTA’ s particular strengths? Keeping an eye on transmission capacity usage

NTA determines the individuals, applications, methods, as well as IP address groups consuming the most data transfer, along with tracking discussions amongst inner and also exterior endpoints.

Transmission capacity monitoring and also source recognition is boosted by utilizing Cisco NBAR2 (next-generation Network-Based Application Acknowledgment) to aid determine common applications and also application categories; Cisco WLC (Wireless LAN Controller) web traffic monitoring to track the applications as well as customers consuming cordless data transfer; and also the SolarWinds Customer Device Tracker to recognize bandwidth hogs as well as their locations.

Examining web traffic patterns

NTA accumulates website traffic data, correlates it, and also presents it in its web console. NTA can give one-minute granularity as well as examine historic information over months, days, and also mins. It sustains drilling to private devices and also interfaces.

Assessing performance

The PerfStack efficiency evaluation dashboard lets you drag and go down efficiency metrics onto a common timeline so you can visually correlate network actions across heaps as well as more quickly find root causes.

CBQoS plan optimization

When you rely on solutions like VoIP as well as cloud applications, intelligently prioritizing and also handling web traffic ends up being vital. NTA allows you compare the performance of pre- and post-policy website traffic levels to establish if your QoS policies are functioning and also prioritized web traffic is streaming as prepared.

Bandwidth capacity planning

Your capacity preparation can be much more informative when you can see what your data transfer utilization patterns are and also identify vital customers. Assessing background lets you recognize patterns of top use. You can after that readjust plans, forestall interruptions, as well as avoid buying additional bandwidth when it’ s not needed

. System requirements

As discussed above, NetFlow Traffic Analyzer is an add-on component for the SolarWinds Network Efficiency Monitor. NTA uses NPM’ s data source and node administration facilities. NPM and also NTA, along with the various other major tools in SolarWinds’ network monitoring collection, are built on a typical backend, Orion. Orion provides the unified interface, systematized administration, as well as accessibility control, and also shared functionality for navigation, setups, alerts, and also records.

Orion architecture

NTA and also NPM run on Windows. They are enterprise-grade bundles, so even the 30-day totally free test needs considerable sources on your system.

For manufacturing use in all however the tiniest stores, SolarWinds suggests 3 web servers:

SolarWinds defines system demands and also finest techniques permanently performance and also best results. Recommendations for OS version, CPU speed and variety of cores, quantity of RAM, NIC speed, and also disk-array setup differ depending upon the variety of network components being kept an eye on (from less than 1,000 approximately above 6,000). Nevertheless, NTA itself is completely demanding that an NTA install ought to constantly be treated as a big installment.

For bigger networks still, you can scale up even more by including more web servers as extra polling engines.


Installation of the NetFlow Web traffic Analyzer is straightforward –– once you have the requirements in position. As discussed over, for a manufacturing setting the suggestion is for 3 semi-dedicated web servers with adequate hardware and specific system software pre-installed.

Because NTA is a component of NPM, you have to mount NPM initially. As soon as unzipped, the installer checks for requirements, sets up missing out on system software and then launches the configuration wizard. The wizard will guide you through providing the required information, and then carries out auto-discovery of the tools on your network.

Exploration will certainly be most valuable if the tools you wish to monitor have actually already been configured to respond to questions for metrics and also occasionally export circulation information. So you need to allow SNMP and also WMI on the network tools and also hosts of passion. As well as you’ ll wish to make it possible for the flow procedures sustained by the gadgets of passion so they send out flow information to NTA.

On NPM (and NTA), as soon as discovery is total, you require to choose which of the now-known devices you intend to import right into the Orion database as well as begin keeping an eye on. SolarWinds recommends you start with a limited variety of vital tools and web servers, and then broaden as shown. (You can constantly see the list of well-known tools via browsing to My Control panels > > Network > Network Summary.)

Once NPM is set up, you set up NTA on the Orion application web server following the very same pattern. There is a hands-on action to move the flow storage space data source to its very own server.


The crucial setup job is occupying NPM and NTA with the listing of devices to be kept an eye on, which occurs during installment, defined over.

For finest efficiency and arises from surveillance, SolarWinds supplies standards for ideal methods about where on your network you ought to be capturing circulation information as well as exactly how to configure storage as well as retention.

Daily use

Daily use of NPM and NTA entails identifying and also fixing network issues and also determining patterns as well as trends in network traffic. This is done using internet console sights, alerts, and also reports. (SolarWinds offers a live demonstration of NTA to try the user interface.)

Orion main dashboard

In the internet console, the first view consists of a list of tabs. The Home as well as Network tab are contributed by NPM; other tabs come from set up components, such as NetFlow from NTA. Each tab details numerous views –– pages you can go to –– which use graphs, tables, as well as text to reveal details and also statistics concerning the monitored components of your network.

In the various sights, network aspects are color coded. A red or partly red element needs focus; a yellow one has a caution. Likewise, the numerous Top 10 checklists (Network Top 10, Leading 10 Interfaces by Percent Application, Leading 10 Errors and also Disposes of Today, etc) rapidly emphasize elements in your network that have wellness problems. The Leading Talkers listings are especially helpful for spotting incipient data transfer problems.

NTA dashboard

The default view for NTA has numerous sections like Leading 5 Applications, Leading 5 Endpoints, Top 5 Discussions, Leading 10 Sources by % Usage, and so on

. Graphics are interactive. Floating over an aspect creates a popup with information concerning it. You can rapidly remove clutter to focus on relevant sorts of data as well as time ranges of rate of interest. Such tailored views can be saved for reuse.

Alerts –– both predefined as well as custom ones you have added –– are caused when a problem is detected. A node decreasing is a predefined alert; notifies can additionally include points like an interface decreasing or becoming overloaded.

Set off notifies turn up in the Active Alerts section of the first view. They can also be sent to you by e-mail or SMS text or various other means, based upon your sharp configurations. You can define that an alert message should consist of pertinent network condition details and also web links to relevant sights in the internet console.

For transmission capacity, the capacity to tailor signals is especially useful. You can readjust the thresholds for receive as well as transmit percent application to be notified of troubles such as transmission capacity hogs.

When investigating a component or alert, you can pierce down into it in the sight to obtain even more in-depth condition as well as metrics. These aid determine if this is a brief issue or a relentless issue and assistance identify the source.

Analyzing information.

When a particular user interface comes to be a problem you can analyze its details. You can likewise use Flow Navigator filters to create a personalized view that concentrates on devices, applications, and also amount of time of passion.

NTA makes it very easy to determine the customers, applications, and methods taking in the most bandwidth. You can arrange by ports, resource, location, and also protocols, and also sight traffic patterns over mins, days or months.

There’ s an array of predefined records, and centers to develop personalized records, that procedure circulation data right into graphes and tables showing how the network is being used as well as how that’ s changing in time. You can set up records to be instantly run as well as supplied. Predefined records such as “& ldquo; Typical and Peak Website Traffic Rates –– WAN Interfaces Last 7 Days” & rdquo; show what beneficial details can be acquired to aid bandwidth ability planning.
