The SolarWinds NetFlow Web Traffic Analyzer (NTA) could well be called the Network Traffic Analyzer because it takes care of not just the original Cisco NetFlow however most of its variants from various other makers, along with NetFlow’ s main alternative, sFlow.(That s why we covered NTA in our testimonial of sFlow enthusiasts and analyzers.)

SolarWinds NTA is not a standalone tool, however rather a component that can be contributed to SolarWinds’ Network Performance Screen(NPM). The mix of these two modules produce a total network checking software. NTA as well as NPM incorporate with the rest of SolarWinds’ Orion platform devices, such as the Network Configuration Manager.

NTA gathers interface-level circulation data as well as Cisco Class-Based High Quality of Service (CBQoS) data, integrating them with performance data that NPM gathers from SNMP, WMI, and various other sources. It processes the data to generate interactive charts and also personalized records, giving you “& ldquo; one pane of glass” & rdquo; exposure right into your network’ s condition and its historical actions. NPM and also NTA provide you a wide range of advanced facilities for taking care of multi-vendor networks: transmission capacity surveillance, traffic evaluation, efficiency analysis, notifies, adjustable records, plan optimization, etc. NTA as well as NPM are available in a 30-day fully-functional test, and also pricing depends upon the number of network components you’ ll be keeping track of

A bandwidth screen and web traffic analyzer mostly assists you to identify and also troubleshoot network problems, as well as to recognize web traffic patterns and trends so you can change plans and plan network changes.

What are NTA’ s specific toughness? Keeping track of transmission capacity usage

NTA identifies the users, applications, protocols, and also IP address teams consuming one of the most transmission capacity, along with tracking conversations among internal and also outside endpoints.

Transmission capacity surveillance as well as origin identification is improved by using Cisco NBAR2 (next-generation Network-Based Application Acknowledgment) to help determine typical applications and application categories; Cisco WLC (Wireless LAN Controller) web traffic tracking to track the applications and also users taking in wireless data transfer; and also the SolarWinds Customer Tool Tracker to identify transmission capacity hogs as well as their areas.

Assessing traffic patterns

NTA accumulates traffic information, associates it, as well as offers it in its web console. NTA can supply one-minute granularity and also examine historic data over months, days, and also minutes. It sustains drilling down to private devices and user interfaces.

Analyzing efficiency

The PerfStack efficiency analysis dashboard lets you drag and also drop efficiency metrics onto a common timeline so you can visually associate network actions throughout stacks and also quicker discover source.

CBQoS policy optimization

When you depend upon services like VoIP as well as cloud applications, intelligently focusing on and taking care of traffic ends up being critical. NTA allows you compare the effectiveness of pre- and post-policy web traffic degrees to determine if your QoS policies are working and focused on traffic is streaming as planned.

Data transfer capability preparation

Your capability planning can be much more insightful when you can see what your data transfer usage patterns are as well as determine crucial consumers. Assessing history lets you determine patterns of top use. You can after that readjust policies, forestall blackouts, and prevent buying extra data transfer when it’ s not needed

. System demands

As pointed out above, NetFlow Web Traffic Analyzer is an add-on component for the SolarWinds Network Efficiency Display. NTA utilizes NPM’ s database as well as node monitoring facilities. NPM and NTA, as well as the other significant devices in SolarWinds’ network administration collection, are improved an usual backend, Orion. Orion gives the unified interface, systematized administration, and accessibility control, as well as shared functionality for navigating, setups, signals, as well as records.

Orion style

NTA as well as NPM run on Windows. They are enterprise-grade packages, so also the 30-day free trial needs considerable sources on your system.

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

  • A Windows Web server Orion application server (likewise called the primary poller) holds the web console and does information collection.
  • A SQL Web Server Orion Database Web server stores gathered performance, log, and arrangement information.
  • A SQL Server Flow Storage Database shops the circulation data.

SolarWinds defines system needs as well as best practices completely efficiency and finest results. Referrals for OS version, CPU rate and variety of cores, amount of RAM, NIC speed, and also disk-array configuration differ relying on the variety of network components being monitored (from less than 1,000 as much as greater than 6,000). Nonetheless, NTA itself is sufficiently requiring that an NTA install ought to always be dealt with as a large installation.

For larger networks still, you can scale up additionally by including more servers as additional ballot engines.


Installment of the NetFlow Website traffic Analyzer is straightforward –– as soon as you have the requirements in place. As pointed out above, for a manufacturing atmosphere the suggestion is for 3 semi-dedicated servers with sufficient equipment as well as specific system software pre-installed.

Given that NTA is a component of NPM, you should mount NPM initially. As soon as unzipped, the installer look for prerequisites, sets up missing out on system software and afterwards launches the setup wizard. The wizard will certainly lead you with supplying the required information, and afterwards performs auto-discovery of the devices on your network.

Exploration will certainly be most helpful if the gadgets you wish to keep track of have actually already been set up to address questions for metrics and occasionally export flow data. So you should allow SNMP and also WMI on the network tools and also hosts of rate of interest. As well as you’ ll want to enable the flow protocols sustained by the gadgets of interest so they send out flow data to NTA.

On NPM (as well as NTA), when exploration is full, you require to choose which of the now-known tools you want to import into the Orion database and begin monitoring. SolarWinds recommends you start with a minimal number of vital devices and servers, and after that expand as suggested. (You can constantly see the list of known gadgets through browsing to My Dashboards > > Network > Network Summary.)

When NPM is set up, you mount NTA on the Orion application web server adhering to the exact same pattern. There is a manual step to relocate the flow storage data source to its own web server.


The crucial configuration job is occupying NPM and NTA with the list of tools to be kept an eye on, which takes place throughout installment, defined over.

For best performance as well as results from surveillance, SolarWinds provides guidelines for best techniques concerning where on your network you should be catching circulation information and also how to configure storage space and retention.

Daily usage

Daily use of NPM and NTA entails discovering as well as repairing network problems and also determining patterns and also fads in network traffic. This is done using web console views, signals, and reports. (SolarWinds gives a live demonstration of NTA to experiment with the user interface.)

Orion primary control panel

In the internet console, the preliminary view consists of a list of tabs. The Residence and also Network tab are added by NPM; various other tabs originate from installed components, such as NetFlow from NTA. Each tab notes numerous sights –– web pages you can go to –– which use graphs, tables, and also message to reveal information as well as statistics regarding the monitored aspects of your network.

In the different sights, network components are color coded. A red or partly red aspect needs interest; a yellow one has a caution. Additionally, the different Top 10 listings (Network Top 10, Top 10 User Interfaces by Percent Application, Leading 10 Mistakes and also Discards Today, etc) quickly emphasize aspects in your network that have health issues. The Top Talkers checklists are especially beneficial for detecting incipient bandwidth troubles.

NTA dashboard

The default view for NTA contains multiple areas like Top 5 Applications, Leading 5 Endpoints, Top 5 Discussions, Leading 10 Sources by % Application, etc.

. Graphics are interactive. Hovering over an aspect produces a popup with information concerning it. You can quickly strain mess to concentrate on relevant kinds of data and also time varieties of passion. Such customized sights can be saved for reuse.

Alerts –– both predefined as well as personalized ones you have actually added –– are activated when a trouble is detected. A node going down is a predefined alert; notifies can also include things like a user interface going down or ending up being overloaded.

Caused alerts turn up in the Active Alerts area of the preliminary view. They can also be sent to you by email or SMS message or other methods, based on your alert configurations. You can define that an alert message needs to include pertinent network condition info as well as links to relevant sights in the web console.

For transmission capacity, the capability to customize signals is especially useful. You can readjust the thresholds for receive and send percent use to be alerted of troubles such as bandwidth hogs.

When investigating an aspect or alert, you can pierce down into it in the sight to get even more thorough condition and also metrics. These assist establish if this is a short-term trouble or a relentless issue and also help determine the root cause.

Taking a look at information.

When a certain interface comes to be a worry you can analyze its information. You can also use Circulation Navigator filters to develop a personalized view that focuses on devices, applications, as well as time periods of passion.

NTA makes it simple to recognize the individuals, applications, and methods eating the most transmission capacity. You can arrange by ports, resource, destination, and protocols, and view traffic patterns over minutes, days or months.

There’ s an array of predefined records, and also facilities to develop customized reports, that procedure flow information into graphes and also tables showing how the network is being used and also how that’ s transforming with time. You can schedule reports to be automatically run and supplied. Predefined records such as “& ldquo; Average as well as Peak Traffic Rates –– WAN Interfaces Last 7 Days” & rdquo; reveal what helpful details can be acquired to aid data transfer capacity planning.
