SolarWinds NetFlow Website Traffic Analyzer Evaluation


The SolarWinds NetFlow Web Traffic Analyzer (NTA) could well be called the Network Web traffic Analyzer because it takes care of not simply the original Cisco NetFlow however many of its variants from various other suppliers, in addition to NetFlow’ s key alternative, sFlow.(That s why we covered NTA in our testimonial of sFlow enthusiasts and analyzers.)

SolarWinds NTA is not a standalone tool, yet instead a component that can be contributed to SolarWinds’ Network Performance Screen(NPM). The combination of these two modules produce a total network keeping an eye on software package. NTA as well as NPM incorporate with the rest of SolarWinds’ Orion platform tools, such as the Network Setup Supervisor.

NTA collects interface-level flow data and also Cisco Class-Based Top Quality of Service (CBQoS) information, integrating them with performance data that NPM accumulates from SNMP, WMI, as well as various other sources. It processes the data to create interactive graphs and personalized reports, providing you “& ldquo; one pane of glass” & rdquo; visibility right into your network’ s status and its historic habits. NPM and NTA use you a wide variety of advanced facilities for managing multi-vendor networks: data transfer monitoring, traffic evaluation, performance evaluation, alerts, personalized records, policy optimization, etc. NTA and NPM are readily available in a 30-day fully-functional test, and prices depends on the variety of network elements you’ ll be keeping an eye on

A bandwidth display and traffic analyzer mainly helps you to detect as well as repair network problems, as well as to recognize traffic patterns and also trends so you can adjust plans as well as strategy network adjustments.

What are NTA’ s specific strengths? Keeping an eye on transmission capacity use

NTA identifies the individuals, applications, methods, and IP address teams consuming the most bandwidth, along with tracking conversations among interior and also exterior endpoints.

Data transfer monitoring and also origin identification is boosted by utilizing Cisco NBAR2 (next-generation Network-Based Application Acknowledgment) to assist recognize common applications and also application classifications; Cisco WLC (Wireless LAN Controller) website traffic tracking to track the applications and individuals eating cordless transmission capacity; and also the SolarWinds Customer Device Tracker to recognize transmission capacity hogs as well as their places.

Evaluating traffic patterns

NTA accumulates website traffic data, associates it, and also provides it in its web console. NTA can provide one-minute granularity as well as assess historic information over months, days, and also mins. It supports piercing to individual gadgets and interfaces.

Examining performance

The PerfStack performance evaluation dashboard lets you drag and also drop performance metrics onto a typical timeline so you can aesthetically associate network actions throughout stacks as well as quicker discover source.

CBQoS plan optimization

When you depend on services like VoIP and also cloud applications, wisely focusing on and handling website traffic comes to be vital. NTA allows you contrast the effectiveness of pre- and also post-policy web traffic levels to determine if your QoS plans are functioning and focused on traffic is flowing as intended.

Bandwidth capability planning

Your ability preparation can be extra insightful when you can see what your bandwidth usage patterns are and also determine essential customers. Examining background lets you determine patterns of height use. You can then adjust policies, forestall blackouts, as well as prevent acquiring added data transfer when it’ s not needed

. System requirements

As mentioned above, NetFlow Website Traffic Analyzer is an add-on module for the SolarWinds Network Efficiency Monitor. NTA uses NPM’ s database as well as node administration centers. NPM and NTA, along with the various other major tools in SolarWinds’ network monitoring suite, are built on a common backend, Orion. Orion gives the unified user interface, systematized administration, and accessibility control, as well as shared capability for navigation, setups, signals, and also records.

Orion style

NTA and also NPM operate on Windows. They are enterprise-grade packages, so even the 30-day free trial needs significant sources on your system.

For manufacturing usage in all yet the smallest stores, SolarWinds recommends three servers:

  • A Windows Web server Orion app web server (additionally called the primary poller) holds the web console as well as does information collection.
  • A SQL Web Server Orion Database Web server shops collected efficiency, log, and configuration data.
  • A SQL Web Server Circulation Storage space Database shops the flow information.

SolarWinds defines system demands as well as best techniques forever efficiency and finest outcomes. Recommendations for OS variation, CPU rate as well as variety of cores, quantity of RAM, NIC rate, and disk-array arrangement differ depending on the number of network components being kept track of (from less than 1,000 up to more than 6,000). However, NTA itself is sufficiently demanding that an NTA mount should always be dealt with as a big setup.

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


Installment of the NetFlow Traffic Analyzer is straightforward –– as soon as you have the requirements in place. As discussed over, for a production atmosphere the recommendation is for 3 semi-dedicated servers with ample hardware and specific system software pre-installed.

Given that NTA is a module of NPM, you need to set up NPM first. When unzipped, the installer look for requirements, mounts missing system software and afterwards introduces the configuration wizard. The wizard will certainly direct you with offering the needed info, and after that performs auto-discovery of the gadgets on your network.

Exploration will be most beneficial if the devices you want to check have actually already been configured to respond to inquiries for metrics and also regularly export circulation data. So you need to make it possible for SNMP and WMI on the network devices as well as hosts of rate of interest. As well as you’ ll want to make it possible for the flow procedures supported by the gadgets of passion so they send flow information to NTA.

On NPM (as well as NTA), when discovery is full, you require to select which of the now-known devices you want to import into the Orion database and also begin keeping track of. SolarWinds recommends you begin with a minimal number of essential devices and also servers, and after that broaden as shown. (You can always see the listing of known devices through navigating to My Control panels > > Network > Network Recap.)

As soon as NPM is installed, you set up NTA on the Orion application server adhering to the exact same pattern. There is a manual step to relocate the circulation storage space data source to its own web server.


The crucial arrangement job is populating NPM and also NTA with the list of tools to be monitored, which happens throughout setup, defined above.

For ideal performance and results from monitoring, SolarWinds offers guidelines for best techniques about where on your network you should be catching circulation information and also just how to set up storage as well as retention.

Daily use

Daily use of NPM and NTA entails spotting as well as fixing network troubles and also identifying patterns and also trends in network traffic. This is done using web console views, alerts, and reports. (SolarWinds offers a online demonstration of NTA to experiment with the interface.)

Orion major control panel

In the internet console, the initial sight consists of a checklist of tabs. The Residence and Network tab are added by NPM; other tabs originate from installed components, such as NetFlow from NTA. Each tab lists numerous views –– pages you can check out –– which use charts, tables, and text to reveal details and also stats regarding the monitored elements of your network.

In the numerous sights, network components are color coded. A red or partly red component requires focus; a yellow one has a warning. Also, the various Leading 10 listings (Network Top 10, Top 10 User Interfaces by Percent Utilization, Top 10 Errors and Discards Today, etc) promptly emphasize aspects in your network that have health problems. The Top Talkers listings are particularly helpful for detecting incipient transmission capacity problems.

NTA control panel

The default view for NTA includes several areas like Leading 5 Applications, Leading 5 Endpoints, Leading 5 Discussions, Top 10 Resources by % Use, etc.

. Graphics are interactive. Floating over an element generates a popup with information concerning it. You can quickly strain clutter to focus on relevant types of data as well as time series of passion. Such customized views can be saved for reuse.

Alerts –– both predefined and also personalized ones you have actually added –– are caused when an issue is spotted. A node going down is a predefined alert; alerts can also consist of things like a user interface dropping or becoming overloaded.

Caused signals show up in the Active Alerts area of the first view. They can likewise be sent to you by e-mail or SMS message or various other means, based upon your sharp arrangements. You can specify that an alert message needs to consist of appropriate network status information and web links to pertinent sights in the internet console.

For bandwidth, the ability to customize signals is especially valuable. You can change the thresholds for receive and also transmit percent application to be notified of problems such as transmission capacity hogs.

When exploring a component or alert, you can drill down into it in the sight to get more thorough status and metrics. These help establish if this is a temporary problem or a consistent problem and also aid recognize the source.

Examining details.

When a particular interface ends up being a worry you can analyze its information. You can also utilize Circulation Navigator filters to create a custom-made view that focuses on devices, applications, as well as time periods of rate of interest.

NTA makes it easy to identify the individuals, applications, and protocols taking in the most transmission capacity. You can sort by ports, resource, location, as well as procedures, and also sight traffic patterns over minutes, days or months.

There’ s an array of predefined records, as well as facilities to produce custom-made records, that process flow data right into charts and also tables demonstrating how the network is being made use of as well as exactly how that’ s altering over time. You can schedule reports to be immediately run and provided. Predefined reports such as “& ldquo; Average and Peak Web Traffic Fees –– WAN Interfaces Last 7 Days” & rdquo; reveal what beneficial details can be obtained to aid bandwidth ability preparation.
