SolarWinds NetFlow Web Traffic Analyzer Review

The SolarWinds NetFlow Traffic Analyzer (NTA) might well be called the Network Web traffic Analyzer since it handles not just the original Cisco NetFlow but most of its variations from other manufacturers, as well as NetFlow’ s main option, sFlow.(That s why we covered NTA in our review of sFlow collection agencies and analyzers.)

SolarWinds NTA is not a standalone tool, yet rather a component that can be added to SolarWinds’ Network Efficiency Monitor(NPM). The combination of these two modules develop a complete network keeping track of software. NTA and also NPM integrate with the rest of SolarWinds’ Orion platform devices, such as the Network Setup Manager.

NTA collects interface-level flow data and also Cisco Class-Based Quality of Service (CBQoS) data, incorporating them with efficiency data that NPM gathers from SNMP, WMI, and other sources. It processes the data to produce interactive charts as well as customizable reports, providing you “& ldquo; one pane of glass” & rdquo; presence into your network’ s status as well as its historic habits. NPM and also NTA use you a variety of sophisticated facilities for taking care of multi-vendor networks: bandwidth tracking, web traffic evaluation, performance evaluation, informs, personalized records, plan optimization, etc. NTA and also NPM are available in a 30-day fully-functional trial, as well as rates relies on the number of network aspects you’ ll be keeping an eye on

A bandwidth display and also traffic analyzer primarily helps you to discover and repair network issues, and also to identify web traffic patterns and also fads so you can readjust plans and also strategy network adjustments.

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

NTA recognizes the users, applications, protocols, as well as IP address groups taking in the most data transfer, along with tracking conversations amongst interior as well as outside endpoints.

Transmission capacity tracking as well as root cause recognition is enhanced by utilizing Cisco NBAR2 (next-generation Network-Based Application Recognition) to help determine common applications as well as application categories; Cisco WLC (Wireless LAN Controller) website traffic surveillance to track the applications and also individuals consuming wireless transmission capacity; and the SolarWinds Customer Tool Tracker to recognize data transfer hogs and also their areas.

Examining website traffic patterns

NTA gathers web traffic data, correlates it, as well as offers it in its internet console. NTA can give one-minute granularity and also examine historical information over months, days, and also mins. It sustains drilling to private gadgets as well as interfaces.

Evaluating efficiency

The PerfStack efficiency evaluation control panel lets you drag and go down performance metrics onto a common timeline so you can aesthetically associate network habits across stacks and also quicker locate source.

CBQoS policy optimization

When you depend upon services like VoIP and also cloud applications, wisely focusing on and also handling traffic becomes important. NTA allows you contrast the performance of pre- and also post-policy website traffic levels to figure out if your QoS plans are working and also prioritized traffic is streaming as intended.

Data transfer capacity planning

Your ability preparation can be more informative when you can see what your data transfer utilization patterns are as well as identify key customers. Evaluating background allows you recognize patterns of peak usage. You can then change plans, forestall outages, and also stay clear of acquiring added transmission capacity when it’ s not needed

. System demands

As stated over, NetFlow Website Traffic Analyzer is an add-on component for the SolarWinds Network Performance Monitor. NTA uses NPM’ s data source and node management centers. NPM as well as NTA, as well as the various other significant devices in SolarWinds’ network administration suite, are improved a typical backend, Orion. Orion provides the unified user interface, systematized administration, and also accessibility control, and also shared performance for navigating, settings, alerts, and records.

Orion architecture

NTA and NPM run on Windows. They are enterprise-grade bundles, so also the 30-day complimentary test needs considerable sources on your system.

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

  • A Windows Server Orion app web server (likewise called the primary poller) organizes the web console and also does data collection.
  • A SQL Server Orion Data source Server shops gathered efficiency, log, as well as setup data.
  • A SQL Server Circulation Storage Database stores the circulation information.

SolarWinds specifies system needs as well as ideal methods forever efficiency and also best results. Suggestions for OS version, CPU rate and variety of cores, quantity of RAM, NIC rate, as well as disk-array configuration differ depending upon the variety of network components being kept track of (from less than 1,000 up to above 6,000). Nonetheless, NTA itself is completely requiring that an NTA mount need to constantly be dealt with as a huge installment.

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


Installment of the NetFlow Website traffic Analyzer is straightforward –– once you have the requirements in place. As pointed out above, for a manufacturing setting the suggestion is for 3 semi-dedicated web servers with ample hardware as well as particular system software pre-installed.

Because NTA is a component of NPM, you must set up NPM first. When unzipped, the installer look for prerequisites, mounts missing system software and afterwards releases the arrangement wizard. The wizard will certainly assist you through providing the needed information, and afterwards carries out auto-discovery of the tools on your network.

Discovery will certainly be most valuable if the gadgets you intend to check have already been configured to address questions for metrics as well as periodically export flow data. So you must make it possible for SNMP as well as WMI on the network tools as well as hosts of interest. And also you’ ll intend to enable the flow procedures sustained by the devices of rate of interest so they send circulation information to NTA.

On NPM (as well as NTA), once discovery is complete, you require to pick which of the now-known gadgets you want to import right into the Orion data source as well as begin monitoring. SolarWinds advises you begin with a restricted number of crucial gadgets as well as servers, and afterwards broaden as indicated. (You can constantly see the list of known devices using browsing to My Dashboards > > Network > Network Summary.)

Once NPM is mounted, you set up NTA on the Orion app web server complying with the very same pattern. There is a manual action to move the circulation storage space database to its very own server.


The key arrangement job is populating NPM as well as NTA with the checklist of gadgets to be checked, which takes place during setup, defined over.

For finest performance and also results from tracking, SolarWinds offers guidelines for finest practices concerning where on your network you need to be recording flow information and also exactly how to set up storage space and also retention.

Daily usage

Daily use NPM and also NTA involves discovering as well as troubleshooting network problems and determining patterns as well as patterns in network web traffic. This is done through internet console sights, alerts, and records. (SolarWinds gives a real-time trial of NTA to check out the user interface.)

Orion major dashboard

In the web console, the first sight consists of a checklist of tabs. The House as well as Network tab are added by NPM; other tabs originate from installed components, such as NetFlow from NTA. Each tab provides several sights –– web pages you can see –– which make use of graphs, tables, as well as text to reveal details as well as statistics regarding the monitored components of your network.

In the numerous views, network components are color coded. A red or partly red aspect requires focus; a yellow one has a caution. Additionally, the various Leading 10 lists (Network Top 10, Top 10 Interfaces by Percent Usage, Leading 10 Errors as well as Disposes of Today, etc) swiftly emphasize elements in your network that have health concerns. The Top Talkers lists are especially useful for identifying incipient bandwidth problems.

NTA control panel

The default view for NTA has multiple sections like Leading 5 Applications, Top 5 Endpoints, Leading 5 Discussions, Leading 10 Sources by % Use, and so on

. Graphics are interactive. Hovering over a component produces a popup with details about it. You can swiftly strain clutter to focus on relevant kinds of information and also time varieties of interest. Such tailored sights can be saved for reuse.

Alerts –– both predefined and personalized ones you have added –– are set off when a trouble is spotted. A node dropping is a predefined alert; signals can additionally consist of things like a user interface going down or coming to be overloaded.

Caused alerts show up in the Energetic Alerts section of the preliminary sight. They can additionally be sent to you by email or SMS message or various other ways, based on your alert configurations. You can define that an alert message needs to consist of appropriate network status details and also links to pertinent views in the web console.

For transmission capacity, the capacity to customize informs is especially valuable. You can change the thresholds for obtain and send percent usage to be informed of problems such as transmission capacity hogs.

When examining an aspect or alert, you can drill down right into it in the view to get more in-depth condition as well as metrics. These assist determine if this is a temporary problem or a consistent concern and help determine the root cause.

Taking a look at details.

When a specific user interface comes to be a concern you can examine its details. You can additionally utilize Circulation Navigator filters to develop a customized sight that focuses on gadgets, applications, and also amount of time of passion.

NTA makes it easy to recognize the customers, applications, as well as protocols consuming one of the most bandwidth. You can sort by ports, source, destination, as well as procedures, and also view traffic patterns over minutes, days or months.

There’ s an array of predefined reports, and facilities to produce customized records, that procedure circulation information right into graphes and also tables demonstrating how the network is being used as well as just how that’ s changing in time. You can schedule records to be immediately run and delivered. Predefined records such as “& ldquo; Average and Peak Traffic Rates –– WAN Interfaces Last 7 Days” & rdquo; reveal what valuable information can be gotten to aid data transfer capacity preparation.

Real-Time NetFlow Analyzer (FREE DEVICE)

If you have a little network as well as you wear’ t feel that you might validate the cost of getting in the high-grade NetFlow Website traffic Analyzer, you must think about the free Real-time NetFlow Analyzer. This device has the glossy feel and look of the paid SolarWinds tool, however not as many functions.

This is an excellent bandwidth usage display, but you must understand every one of the energies that you don’ t get with this tool, but you would certainly get with the NetFlow Traffic Analyzer. These include analytical functions, such as Network traffic forensics and also CBQoS efficiency metrics. The free device additionally won’ t give you the web traffic alerts and also flow reporting that you get with the paid SolarWinds energy. The network status functions of the NetFlow Website traffic Analyzer are additionally lacking from the totally free variation. These consist of incorporated mistake, efficiency, as well as schedule surveillance plus network gadget arrangement administration facilities.
