The SolarWinds NetFlow Website Traffic Analyzer (NTA) could well be called the Network Website traffic Analyzer since it handles not simply the initial Cisco NetFlow but a number of its versions from various other producers, in addition to NetFlow’ s key choice, sFlow.(That s why we covered NTA in our review of sFlow collectors as well as analyzers.)

SolarWinds NTA is not a standalone device, however rather a component that can be contributed to SolarWinds’ Network Performance Monitor(NPM). The combination of these 2 modules produce a total network monitoring software package. NTA and also NPM integrate with the rest of SolarWinds’ Orion platform tools, such as the Network Configuration Manager.

NTA gathers interface-level flow data and Cisco Class-Based Quality of Service (CBQoS) information, combining them with performance data that NPM gathers from SNMP, WMI, and also various other sources. It refines the data to create interactive graphs as well as adjustable reports, offering you “& ldquo; one pane of glass” & rdquo; visibility right into your network’ s status as well as its historic behavior. NPM as well as NTA supply you a wide range of sophisticated facilities for handling multi-vendor networks: transmission capacity surveillance, traffic evaluation, performance analysis, informs, adjustable reports, policy optimization, etc. NTA and NPM are available in a 30-day fully-functional trial, and also rates depends upon the variety of network elements you’ ll be keeping track of

A data transfer screen and web traffic analyzer primarily aids you to find and fix network issues, and to identify web traffic patterns as well as fads so you can adjust plans and also strategy network modifications.

What are NTA’ s certain strengths? Keeping an eye on data transfer usage

NTA identifies the customers, applications, procedures, as well as IP address groups eating one of the most bandwidth, along with tracking conversations amongst internal as well as external endpoints.

Transmission capacity monitoring and also origin recognition is improved by utilizing Cisco NBAR2 (next-generation Network-Based Application Recognition) to assist determine typical applications and application groups; Cisco WLC (Wireless LAN Controller) website traffic surveillance to track the applications and users taking in cordless data transfer; and the SolarWinds User Gadget Tracker to recognize bandwidth hogs and their places.

Analyzing website traffic patterns

NTA accumulates traffic data, associates it, and presents it in its web console. NTA can give one-minute granularity and assess historic data over months, days, as well as mins. It supports drilling down to specific devices and user interfaces.

Assessing performance

The PerfStack performance evaluation dashboard lets you drag and drop efficiency metrics onto a typical timeline so you can aesthetically correlate network habits throughout heaps and faster discover origin.

CBQoS plan optimization

When you depend on solutions like VoIP and cloud applications, smartly focusing on as well as managing traffic becomes essential. NTA lets you compare the performance of pre- and also post-policy traffic degrees to figure out if your QoS plans are working as well as prioritized website traffic is flowing as prepared.

Bandwidth capacity planning

Your ability planning can be a lot more insightful when you can see what your transmission capacity use patterns are and identify key customers. Examining history allows you identify patterns of peak use. You can after that readjust plans, forestall failures, and avoid getting added transmission capacity when it’ s not needed

. System demands

As discussed above, NetFlow Traffic Analyzer is an add-on module for the SolarWinds Network Efficiency Display. NTA uses NPM’ s data source and node monitoring centers. NPM and also NTA, in addition to the other major tools in SolarWinds’ network monitoring suite, are improved a common backend, Orion. Orion offers the unified interface, streamlined administration, and accessibility control, and also shared performance for navigating, setups, informs, and reports.

Orion design

NTA and NPM work on Windows. They are enterprise-grade plans, so even the 30-day cost-free test needs considerable resources on your system.

For manufacturing usage in all but the smallest stores, SolarWinds advises 3 web servers:

  • A Windows Web server Orion application web server (additionally called the main poller) organizes the internet console as well as does data collection.
  • A SQL Web Server Orion Data source Web server shops gathered performance, log, as well as configuration information.
  • A SQL Server Circulation Storage Data source shops the flow data.

SolarWinds defines system needs as well as ideal methods forever efficiency and best results. Referrals for OS variation, CPU speed and number of cores, quantity of RAM, NIC speed, and disk-array configuration differ depending upon the number of network components being kept track of (from less than 1,000 approximately higher than 6,000). However, NTA itself is completely requiring that an NTA install ought to constantly be dealt with as a huge installation.

For larger networks still, you can scale up even more by including extra servers as added ballot engines.


Installment of the NetFlow Traffic Analyzer is straightforward –– once you have the prerequisites in position. As mentioned over, for a production atmosphere the recommendation is for 3 semi-dedicated servers with ample equipment as well as particular system software pre-installed.

Considering that NTA is a component of NPM, you have to install NPM initially. As soon as unzipped, the installer look for requirements, sets up missing system software and afterwards releases the arrangement wizard. The wizard will direct you via offering the required details, and then executes auto-discovery of the gadgets on your network.

Discovery will certainly be most helpful if the gadgets you wish to check have already been configured to address questions for metrics as well as periodically export circulation data. So you should make it possible for SNMP as well as WMI on the network devices as well as hosts of passion. And also you’ ll want to make it possible for the circulation protocols supported by the gadgets of passion so they send out circulation information to NTA.

On NPM (and NTA), once discovery is full, you need to pick which of the now-known tools you want to import into the Orion data source and also begin keeping track of. SolarWinds suggests you begin with a limited variety of key tools and also servers, and after that expand as shown. (You can constantly see the list of known tools by means of navigating to My Control panels > > Network > Network Summary.)

When NPM is installed, you mount NTA on the Orion application server following the exact same pattern. There is a manual action to move the circulation storage space database to its own server.


The essential setup job is inhabiting NPM and NTA with the checklist of tools to be checked, which takes place throughout setup, described above.

For best efficiency and results from monitoring, SolarWinds supplies standards for ideal techniques concerning where on your network you ought to be catching flow data and just how to configure storage space and retention.

Daily use

Daily use NPM and NTA involves finding as well as troubleshooting network issues as well as identifying patterns and trends in network web traffic. This is done through internet console views, notifies, and also reports. (SolarWinds offers a online demonstration of NTA to try the user interface.)

Orion major dashboard

In the web console, the initial sight includes a listing of tabs. The House as well as Network tab are contributed by NPM; various other tabs come from set up components, such as NetFlow from NTA. Each tab lists multiple views –– web pages you can check out –– which make use of graphs, tables, and also message to show details and also stats concerning the monitored aspects of your network.

In the numerous views, network elements are color coded. A red or partly red element requires attention; a yellow one has a warning. Also, the various Leading 10 lists (Network Top 10, Leading 10 User Interfaces by Percent Application, Leading 10 Mistakes and Disposes of Today, etc) quickly highlight components in your network that have health concerns. The Top Talkers listings are especially valuable for detecting incipient transmission capacity issues.

NTA control panel

The default view for NTA has multiple areas like Top 5 Applications, Top 5 Endpoints, Top 5 Conversations, Leading 10 Resources by % Utilization, and so on

. Graphics are interactive. Floating over an element generates a popup with information regarding it. You can quickly strain mess to concentrate on relevant sorts of data as well as time series of rate of interest. Such customized views can be saved for reuse.

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

Activated notifies show up in the Active Alerts section of the initial view. They can also be sent out to you by e-mail or SMS text or various other ways, based upon your alert setups. You can define that a sharp message must consist of relevant network status information as well as links to appropriate sights in the web console.

For bandwidth, the capacity to tailor notifies is especially beneficial. You can change the limits for receive and transfer percent utilization to be informed of troubles such as bandwidth hogs.

When exploring a component or alert, you can drill down right into it in the view to obtain even more thorough standing and also metrics. These help establish if this is a momentary issue or a consistent issue as well as help identify the origin.

Checking out information.

When a specific interface comes to be an issue you can analyze its information. You can additionally make use of Circulation Navigator filters to develop a custom-made view that concentrates on gadgets, applications, as well as time periods of passion.

NTA makes it simple to identify the individuals, applications, as well as methods eating one of the most data transfer. You can sort by ports, resource, location, and also protocols, and also sight traffic patterns over mins, days or months.

There’ s a variety of predefined reports, and also centers to produce custom-made reports, that procedure circulation information right into charts and tables demonstrating how the network is being used and just how that’ s changing in time. You can set up reports to be automatically run and also delivered. Predefined records such as “& ldquo; Typical as well as Peak Website Traffic Rates –– WAN Interfaces Last 7 Days” & rdquo; show what helpful details can be acquired to aid bandwidth ability planning.

Real-Time NetFlow Analyzer (FREE TOOL)

If you have a small network and you don’ t really feel that you could justify the expense of entering the state-of-the-art NetFlow Traffic Analyzer, you ought to think about the free Real-time NetFlow Analyzer. This tool has the slick look of the paid SolarWinds tool, yet not as many attributes.

This is a wonderful bandwidth use monitor, but you must know every one of the energies that you don’ t get with this device, but you would certainly get with the NetFlow Traffic Analyzer. These consist of logical functions, such as Network web traffic forensics and also CBQoS efficiency metrics. The complimentary tool likewise won’ t offer you the traffic informs and flow reporting that you get with the paid SolarWinds utility. The network condition features of the NetFlow Web traffic Analyzer are likewise missing from the free version. These consist of integrated fault, performance, and also schedule surveillance plus network gadget setup monitoring facilities.
