The SolarWinds NetFlow Website Traffic Analyzer (NTA) might well be called the Network Traffic Analyzer given that it manages not simply the original Cisco NetFlow however many of its versions from various other makers, as well as NetFlow’ s primary choice, sFlow.(That s why we covered NTA in our testimonial of sFlow collectors as well as analyzers.)

SolarWinds NTA is not a standalone tool, however rather a component that can be added to SolarWinds’ Network Performance Display(NPM). The combination of these two modules develop a complete network keeping an eye on software. NTA as well as NPM incorporate with the remainder of SolarWinds’ Orion platform tools, such as the Network Configuration Supervisor.

NTA collects interface-level flow data as well as Cisco Class-Based Top Quality of Service (CBQoS) data, incorporating them with efficiency data that NPM accumulates from SNMP, WMI, and other resources. It processes the data to produce interactive charts and also customizable reports, providing you “& ldquo; one pane of glass” & rdquo; presence right into your network’ s status as well as its historical actions. NPM and NTA provide you a large range of innovative facilities for managing multi-vendor networks: data transfer tracking, traffic evaluation, performance analysis, notifies, personalized reports, plan optimization, etc. NTA as well as NPM are available in a 30-day fully-functional test, as well as pricing depends upon the number of network elements you’ ll be keeping track of

A transmission capacity monitor and also traffic analyzer mostly aids you to detect and also fix network troubles, as well as to identify web traffic patterns and trends so you can change plans and also strategy network changes.

What are NTA’ s specific staminas? Checking data transfer usage

NTA determines the customers, applications, protocols, and IP address teams eating one of the most transmission capacity, along with tracking conversations among internal as well as outside endpoints.

Bandwidth surveillance and source recognition is boosted by using Cisco NBAR2 (next-generation Network-Based Application Recognition) to aid identify usual applications and also application categories; Cisco WLC (Wireless LAN Controller) web traffic surveillance to track the applications and also users taking in cordless transmission capacity; as well as the SolarWinds Customer Device Tracker to recognize bandwidth hogs and their locations.

Evaluating website traffic patterns

NTA gathers website traffic information, associates it, and presents it in its internet console. NTA can supply one-minute granularity as well as analyze historical data over months, days, and minutes. It supports piercing to private tools as well as interfaces.

Analyzing performance

The PerfStack performance evaluation dashboard lets you drag as well as drop efficiency metrics onto a typical timeline so you can aesthetically associate network habits throughout stacks and more quickly find root causes.

CBQoS policy optimization

When you rely on solutions like VoIP as well as cloud applications, wisely focusing on as well as managing website traffic comes to be critical. NTA lets you compare the effectiveness of pre- as well as post-policy website traffic degrees to identify if your QoS policies are working and focused on website traffic is flowing as prepared.

Data transfer capacity planning

Your ability planning can be more insightful when you can see what your data transfer utilization patterns are and also determine crucial consumers. Evaluating background lets you identify patterns of top usage. You can after that change policies, forestall failures, and stay clear of acquiring extra transmission capacity when it’ s not required

. System requirements

As pointed out over, NetFlow Web Traffic Analyzer is an add-on component for the SolarWinds Network Performance Monitor. NTA makes use of NPM’ s data source and also node monitoring facilities. NPM and also NTA, as well as the other major devices in SolarWinds’ network monitoring suite, are built on a common backend, Orion. Orion gives the unified interface, centralized management, and also gain access to control, as well as shared capability for navigation, settings, alerts, and also reports.

Orion style

NTA as well as NPM operate on Windows. They are enterprise-grade packages, so also the 30-day totally free test demands considerable resources on your system.

For production usage in all however the tiniest shops, SolarWinds suggests three servers:

  • A Windows Server Orion app web server (additionally called the primary poller) organizes the internet console and does data collection.
  • A SQL Web Server Orion Data source Server shops collected performance, log, and setup information.
  • A SQL Web Server Flow Storage space Data source stores the circulation data.

SolarWinds defines system requirements as well as ideal practices completely efficiency and also ideal results. Referrals for OS variation, CPU speed and also number of cores, quantity of RAM, NIC speed, as well as disk-array arrangement vary depending on the variety of network elements being monitored (from less than 1,000 approximately greater than 6,000). Nonetheless, NTA itself is adequately requiring that an NTA set up ought to constantly be treated as a huge setup.

For bigger networks still, you can scale up further by adding extra web servers as added ballot engines.


Installment of the NetFlow Website traffic Analyzer is straightforward –– once you have the requirements in position. As mentioned above, for a manufacturing atmosphere the recommendation is for 3 semi-dedicated servers with appropriate equipment as well as certain system software pre-installed.

Since NTA is a module of NPM, you should set up NPM first. As soon as unzipped, the installer checks for requirements, installs missing system software and afterwards launches the arrangement wizard. The wizard will guide you through supplying the needed info, and after that does auto-discovery of the devices on your network.

Discovery will certainly be most helpful if the devices you want to check have actually currently been set up to respond to inquiries for metrics and also regularly export flow data. So you need to allow SNMP as well as WMI on the network devices and also hosts of rate of interest. And you’ ll intend to make it possible for the flow protocols sustained by the tools of rate of interest so they send flow data to NTA.

On NPM (and also NTA), when discovery is total, you need to choose which of the now-known gadgets you want to import right into the Orion database and start keeping an eye on. SolarWinds suggests you begin with a limited variety of key gadgets and web servers, and after that expand as suggested. (You can always see the list of well-known tools via browsing to My Control panels > > Network > Network Recap.)

When NPM is mounted, you set up NTA on the Orion application server following the very same pattern. There is a hand-operated step to move the circulation storage data source to its own server.


The crucial configuration job is inhabiting NPM and also NTA with the checklist of gadgets to be kept track of, which takes place during installation, described over.

For ideal efficiency as well as arises from surveillance, SolarWinds gives guidelines for ideal practices about where on your network you should be capturing circulation information and also just how to configure storage and retention.

Daily use

Daily use NPM as well as NTA entails finding as well as repairing network issues and identifying patterns as well as trends in network traffic. This is done through internet console views, signals, as well as records. (SolarWinds offers a live demo of NTA to try the interface.)

Orion main dashboard

In the web console, the initial view includes a list of tabs. The Residence as well as Network tab are added by NPM; various other tabs come from installed modules, such as NetFlow from NTA. Each tab details several sights –– web pages you can go to –– which use charts, tables, as well as text to show details as well as statistics regarding the monitored components of your network.

In the numerous views, network aspects are color coded. A red or partially red component needs focus; a yellow one has a warning. Also, the different Leading 10 checklists (Network Top 10, Top 10 Interfaces by Percent Application, Top 10 Errors and also Discards Today, etc) promptly highlight components in your network that have health and wellness concerns. The Top Talkers listings are especially helpful for finding incipient data transfer issues.

NTA control panel

The default sight for NTA has several areas like Top 5 Applications, Top 5 Endpoints, Top 5 Discussions, Top 10 Resources by % Use, and so on

. Graphics are interactive. Hovering over an aspect creates a popup with details about it. You can rapidly strain mess to focus on pertinent kinds of data and also time ranges of passion. Such customized views can be saved for reuse.

Alerts –– both predefined and also custom-made ones you have added –– are caused when an issue is spotted. A node dropping is a predefined alert; notifies can additionally consist of points like a user interface going down or becoming overloaded.

Caused notifies show up in the Active Alerts section of the first sight. They can also be sent to you by e-mail or SMS message or other means, based upon your sharp arrangements. You can define that an alert message must include pertinent network standing info as well as web links to relevant views in the internet console.

For bandwidth, the capacity to tailor alerts is specifically valuable. You can adjust the thresholds for receive and also transmit percent utilization to be notified of problems such as transmission capacity hogs.

When checking out an element or alert, you can drill down right into it in the view to obtain more detailed condition as well as metrics. These assist figure out if this is a brief trouble or a consistent issue and also aid identify the origin.

Checking out information.

When a certain interface comes to be an issue you can analyze its information. You can additionally make use of Flow Navigator filters to produce a personalized view that focuses on gadgets, applications, and time periods of passion.

NTA makes it easy to recognize the users, applications, as well as protocols eating one of the most transmission capacity. You can arrange by ports, source, destination, and protocols, as well as sight traffic patterns over minutes, days or months.

There’ s a variety of predefined reports, as well as facilities to develop personalized reports, that procedure circulation information right into graphes and also tables showing how the network is being made use of and exactly how that’ s altering gradually. You can schedule reports to be automatically run as well as supplied. Predefined reports such as “& ldquo; Ordinary as well as Peak Traffic Fees –– WAN Interfaces Last 7 Days” & rdquo; show what valuable info can be gotten to aid data transfer capability preparation.
