The SolarWinds NetFlow Website Traffic Analyzer (NTA) could well be called the Network Traffic Analyzer given that it deals with not just the initial Cisco NetFlow but a number of its variants from various other makers, along with NetFlow’ s primary alternative, sFlow.(That s why we covered NTA in our review of sFlow collectors as well as analyzers.)

SolarWinds NTA is not a standalone tool, but rather a component that can be added to SolarWinds’ Network Performance Monitor(NPM). The combination of these two modules develop a total network checking software. NTA and NPM incorporate with the remainder of SolarWinds’ Orion system devices, such as the Network Setup Supervisor.

NTA gathers interface-level flow information as well as Cisco Class-Based Quality of Service (CBQoS) data, combining them with efficiency information that NPM collects from SNMP, WMI, and also various other sources. It refines the data to produce interactive charts as well as personalized reports, giving you “& ldquo; one pane of glass” & rdquo; visibility into your network’ s condition and also its historical behavior. NPM as well as NTA supply you a wide variety of innovative centers for handling multi-vendor networks: transmission capacity monitoring, website traffic evaluation, efficiency evaluation, signals, personalized reports, policy optimization, etc. NTA and also NPM are available in a 30-day fully-functional test, as well as prices relies on the number of network aspects you’ ll be monitoring

A data transfer screen and also traffic analyzer primarily aids you to discover as well as troubleshoot network problems, and to determine website traffic patterns and patterns so you can readjust plans as well as plan network modifications.

What are NTA’ s certain strengths? Keeping an eye on bandwidth use

NTA recognizes the individuals, applications, protocols, and IP address groups eating the most data transfer, as well as tracking discussions amongst interior and also outside endpoints.

Data transfer tracking as well as root cause identification is improved by utilizing Cisco NBAR2 (next-generation Network-Based Application Recognition) to aid determine typical applications as well as application categories; Cisco WLC (Wireless LAN Controller) website traffic tracking to track the applications as well as customers consuming wireless bandwidth; as well as the SolarWinds Individual Gadget Tracker to determine transmission capacity hogs and their places.

Examining web traffic patterns

NTA collects website traffic data, correlates it, and offers it in its internet console. NTA can give one-minute granularity and assess historical information over months, days, and mins. It supports piercing to specific tools as well as interfaces.

Analyzing efficiency

The PerfStack performance evaluation control panel lets you drag and go down efficiency metrics onto a common timeline so you can visually associate network behavior throughout heaps and faster locate root causes.

CBQoS plan optimization

When you depend upon solutions like VoIP and also cloud applications, smartly prioritizing and handling website traffic becomes important. NTA lets you contrast the performance of pre- and also post-policy web traffic levels to figure out if your QoS policies are functioning as well as focused on website traffic is flowing as planned.

Data transfer capability preparation

Your capacity preparation can be more insightful when you can see what your bandwidth utilization patterns are and also identify vital consumers. Reviewing background allows you determine patterns of top usage. You can then change policies, forestall blackouts, and also stay clear of buying additional data transfer when it’ s not required

. System needs

As mentioned over, NetFlow Traffic Analyzer is an add-on component for the SolarWinds Network Efficiency Display. NTA uses NPM’ s data source and also node monitoring facilities. NPM and also NTA, in addition to the other major tools in SolarWinds’ network monitoring collection, are improved a typical backend, Orion. Orion offers the unified interface, systematized administration, and access control, as well as shared functionality for navigation, settings, signals, as well as records.

Orion style

NTA as well as NPM work on Windows. They are enterprise-grade bundles, so even the 30-day cost-free trial demands substantial resources on your system.

For manufacturing use in all however the tiniest shops, SolarWinds recommends three web servers:

  • A Windows Web server Orion app web server (additionally called the major poller) hosts the internet console and does data collection.
  • A SQL Server Orion Data source Server shops collected efficiency, log, and setup data.
  • A SQL Web Server Circulation Storage Data source stores the flow data.

SolarWinds defines system needs and also ideal methods forever performance and finest outcomes. Suggestions for OS variation, CPU rate and also number of cores, amount of RAM, NIC rate, and disk-array arrangement differ depending upon the number of network aspects being checked (from less than 1,000 as much as greater than 6,000). Nevertheless, NTA itself is sufficiently demanding that an NTA install ought to constantly be dealt with as a huge installment.

For larger networks still, you can scale up additionally by adding a lot more web servers as additional polling engines.


Setup of the NetFlow Website traffic Analyzer is straightforward –– once you have the prerequisites in place. As discussed over, for a manufacturing environment the suggestion is for 3 semi-dedicated web servers with adequate hardware as well as specific system software pre-installed.

Since NTA is a component of NPM, you have to set up NPM first. As soon as unzipped, the installer checks for requirements, sets up missing system software and after that releases the setup wizard. The wizard will certainly lead you via supplying the required details, and after that carries out auto-discovery of the devices on your network.

Discovery will be most valuable if the devices you wish to monitor have currently been configured to address queries for metrics and also regularly export circulation information. So you should allow SNMP as well as WMI on the network tools as well as hosts of passion. And you’ ll wish to make it possible for the circulation methods sustained by the gadgets of passion so they send circulation information to NTA.

On NPM (and NTA), as soon as exploration is total, you need to choose which of the now-known tools you wish to import right into the Orion data source and also begin checking. SolarWinds suggests you begin with a minimal variety of crucial gadgets as well as servers, and then broaden as shown. (You can always see the listing of known tools using navigating to My Control panels > > Network > Network Summary.)

When NPM is installed, you set up NTA on the Orion app server following the very same pattern. There is a hand-operated action to relocate the flow storage space database to its own web server.


The crucial arrangement task is occupying NPM as well as NTA with the listing of gadgets to be monitored, which happens during setup, described over.

For finest performance as well as results from monitoring, SolarWinds offers standards for ideal techniques about where on your network you ought to be recording circulation information and also exactly how to configure storage space and retention.

Daily use

Daily use of NPM and NTA includes spotting and fixing network troubles as well as identifying patterns as well as fads in network traffic. This is done via web console sights, signals, as well as records. (SolarWinds offers a online demo of NTA to try out the interface.)

Orion primary dashboard

In the web console, the preliminary sight includes a listing of tabs. The House and also Network tab are contributed by NPM; other tabs come from installed modules, such as NetFlow from NTA. Each tab notes multiple views –– pages you can go to –– which utilize graphs, tables, and message to reveal information and data about the monitored elements of your network.

In the various views, network aspects are color coded. A red or partly red component requires focus; a yellow one has a warning. Additionally, the various Top 10 listings (Network Top 10, Leading 10 User Interfaces by Percent Application, Leading 10 Mistakes and Disposes of Today, etc) rapidly highlight components in your network that have wellness concerns. The Leading Talkers checklists are especially helpful for detecting incipient bandwidth issues.

NTA dashboard

The default view for NTA consists of several sections like Top 5 Applications, Leading 5 Endpoints, Leading 5 Discussions, Top 10 Sources by % Use, etc.

. Graphics are interactive. Floating over an element generates a popup with details regarding it. You can promptly strain clutter to concentrate on relevant types of data and also time ranges of passion. Such tailored views can be saved for reuse.

Alerts –– both predefined as well as custom-made ones you have included –– are activated when a trouble is found. A node going down is a predefined alert; signals can additionally include points like an interface dropping or becoming overloaded.

Caused alerts show up in the Energetic Alerts area of the initial view. They can also be sent out to you by email or SMS message or other ways, based on your sharp configurations. You can specify that an alert message ought to consist of appropriate network standing details as well as web links to appropriate views in the internet console.

For transmission capacity, the capacity to tailor alerts is especially valuable. You can change the limits for receive and also transfer percent usage to be alerted of troubles such as bandwidth hogs.

When examining an element or alert, you can drill down right into it in the sight to get more in-depth condition and metrics. These assist establish if this is a temporary trouble or a relentless issue and also help recognize the source.

Taking a look at details.

When a certain interface becomes a concern you can examine its details. You can also make use of Circulation Navigator filters to produce a custom sight that focuses on devices, applications, and period of interest.

NTA makes it easy to determine the individuals, applications, and procedures consuming the most transmission capacity. You can arrange by ports, source, destination, and methods, and view traffic patterns over minutes, days or months.

There’ s a range of predefined reports, and centers to produce custom reports, that procedure circulation information right into charts and also tables demonstrating how the network is being utilized and also exactly how that’ s altering with time. You can arrange reports to be instantly run and supplied. Predefined records such as “& ldquo; Average and Peak Web Traffic Fees –– WAN Interfaces Last 7 Days” & rdquo; reveal what valuable info can be gotten to aid bandwidth ability preparation.
