SolarWinds NetFlow Traffic Analyzer Evaluation

The SolarWinds NetFlow Traffic Analyzer (NTA) may well be called the Network Traffic Analyzer since it takes care of not just the initial Cisco NetFlow however many of its variations from various other manufacturers, as well as NetFlow’ s primary option, sFlow.(That s why we covered NTA in our testimonial of sFlow collection agencies and analyzers.)

SolarWinds NTA is not a standalone device, however rather a module that can be added to SolarWinds’ Network Efficiency Screen(NPM). The mix of these 2 components develop a full network keeping an eye on software. NTA and also NPM incorporate with the rest of SolarWinds’ Orion platform tools, such as the Network Arrangement Manager.

NTA gathers interface-level circulation information as well as Cisco Class-Based High Quality of Service (CBQoS) information, combining them with performance data that NPM accumulates from SNMP, WMI, and various other resources. It refines the information to produce interactive graphs and also personalized records, providing you “& ldquo; one pane of glass” & rdquo; visibility into your network’ s standing and its historic actions. NPM and also NTA supply you a large range of innovative facilities for handling multi-vendor networks: transmission capacity monitoring, web traffic analysis, performance analysis, notifies, adjustable records, plan optimization, etc. NTA and NPM are available in a 30-day fully-functional test, as well as pricing depends on the variety of network aspects you’ ll be keeping an eye on

A transmission capacity display and also traffic analyzer mostly assists you to detect and fix network issues, and to determine web traffic patterns and also fads so you can change plans and plan network changes.

What are NTA’ s certain toughness? Monitoring data transfer usage

NTA recognizes the users, applications, methods, and also IP address groups eating one of the most transmission capacity, as well as tracking discussions among internal and outside endpoints.

Data transfer tracking as well as origin recognition is improved by using Cisco NBAR2 (next-generation Network-Based Application Acknowledgment) to assist recognize usual applications and application classifications; Cisco WLC (Wireless LAN Controller) website traffic surveillance to track the applications and individuals eating wireless bandwidth; as well as the SolarWinds User Tool Tracker to identify data transfer hogs and also their places.

Examining traffic patterns

NTA accumulates website traffic data, associates it, as well as provides it in its web console. NTA can give one-minute granularity and also examine historic information over months, days, and minutes. It sustains piercing to specific tools and also user interfaces.

Assessing performance

The PerfStack efficiency evaluation control panel lets you drag and drop efficiency metrics onto an usual timeline so you can visually associate network behavior across heaps and quicker locate origin.

CBQoS policy optimization

When you rely on services like VoIP and also cloud applications, intelligently focusing on as well as handling traffic becomes essential. NTA lets you compare the effectiveness of pre- and post-policy traffic degrees to determine if your QoS plans are working and focused on traffic is flowing as prepared.

Data transfer capability preparation

Your capacity preparation can be much more insightful when you can see what your bandwidth application patterns are as well as identify crucial consumers. Evaluating history lets you determine patterns of peak usage. You can then change policies, forestall outages, as well as stay clear of purchasing added data transfer when it’ s not required

. System needs

As discussed over, NetFlow Website Traffic Analyzer is an add-on component for the SolarWinds Network Performance Monitor. NTA uses NPM’ s data source as well as node monitoring facilities. NPM and also NTA, in addition to the other major devices in SolarWinds’ network administration suite, are improved a common backend, Orion. Orion gives the unified interface, centralized administration, and accessibility control, and shared capability for navigation, settings, signals, and also reports.

Orion architecture

NTA as well as NPM operate on Windows. They are enterprise-grade packages, so also the 30-day complimentary trial needs significant resources on your system.

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

  • A Windows Server Orion application server (also called the main poller) hosts the web console and does data collection.
  • A SQL Server Orion Data source Server shops collected efficiency, log, and arrangement information.
  • A SQL Server Flow Storage space Data source shops the flow data.

SolarWinds defines system demands as well as ideal practices permanently performance and also ideal outcomes. Suggestions for OS version, CPU speed as well as variety of cores, amount of RAM, NIC speed, and disk-array setup vary relying on the number of network elements being kept track of (from less than 1,000 as much as above 6,000). Nevertheless, NTA itself is sufficiently demanding that an NTA install need to always be treated as a huge setup.

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


Installation of the NetFlow Website traffic Analyzer is straightforward –– once you have the requirements in position. As mentioned above, for a manufacturing environment the recommendation is for 3 semi-dedicated web servers with ample hardware and particular system software pre-installed.

Because NTA is a module of NPM, you must set up NPM first. Once unzipped, the installer checks for requirements, mounts missing out on system software and after that launches the configuration wizard. The wizard will certainly guide you through offering the required details, and afterwards performs auto-discovery of the gadgets on your network.

Exploration will certainly be most useful if the gadgets you want to check have actually currently been set up to answer questions for metrics as well as periodically export flow data. So you must make it possible for SNMP and also WMI on the network tools and also hosts of interest. As well as you’ ll wish to make it possible for the circulation methods supported by the gadgets of rate of interest so they send flow data to NTA.

On NPM (as well as NTA), as soon as discovery is total, you require to choose which of the now-known tools you wish to import right into the Orion data source and also begin checking. SolarWinds recommends you start with a restricted number of essential devices and web servers, and then increase as indicated. (You can always see the list of well-known tools via browsing to My Control panels > > Network > Network Summary.)

Once NPM is set up, you mount NTA on the Orion app server following the exact same pattern. There is a hands-on step to relocate the flow storage space data source to its own server.


The essential arrangement job is occupying NPM and also NTA with the checklist of tools to be kept an eye on, which occurs throughout installation, described above.

For best performance as well as results from surveillance, SolarWinds supplies standards for best methods concerning where on your network you should be catching circulation data as well as exactly how to configure storage space and also retention.

Daily usage

Daily use NPM and NTA entails identifying and repairing network troubles as well as recognizing patterns as well as trends in network web traffic. This is done via internet console sights, informs, as well as records. (SolarWinds offers a online demonstration of NTA to experiment with the user interface.)

Orion major control panel

In the internet console, the first view includes a list of tabs. The Home and also Network tab are contributed by NPM; other tabs originate from mounted components, such as NetFlow from NTA. Each tab details several sights –– web pages you can go to –– which utilize graphs, tables, and message to show information and also statistics concerning the monitored aspects of your network.

In the various views, network components are color coded. A red or partially red aspect needs attention; a yellow one has a warning. Also, the different Top 10 listings (Network Top 10, Top 10 Interfaces by Percent Utilization, Top 10 Mistakes and Discards Today, etc) promptly highlight components in your network that have wellness concerns. The Leading Talkers checklists are specifically helpful for finding incipient bandwidth problems.

NTA dashboard

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

. Graphics are interactive. Floating over an aspect generates a popup with details regarding it. You can rapidly filter out mess to focus on relevant sorts of data and time ranges of interest. Such customized sights can be saved for reuse.

Alerts –– both predefined and also customized ones you have added –– are set off when a trouble is found. A node going down is a predefined alert; informs can likewise consist of points like an interface decreasing or coming to be overloaded.

Set off signals appear in the Active Alerts section of the first sight. They can also be sent out to you by email or SMS message or various other means, based on your alert setups. You can specify that a sharp message ought to include appropriate network status information as well as web links to appropriate views in the internet console.

For transmission capacity, the capability to customize informs is especially useful. You can change the thresholds for obtain and transmit percent utilization to be notified of issues such as bandwidth hogs.

When checking out an aspect or alert, you can drill down right into it in the sight to obtain more in-depth condition and also metrics. These aid establish if this is a temporary issue or a relentless issue and aid determine the origin.

Taking a look at details.

When a particular interface becomes a problem you can analyze its details. You can additionally make use of Flow Navigator filters to develop a personalized view that concentrates on devices, applications, and time periods of interest.

NTA makes it easy to identify the individuals, applications, and also methods eating one of the most bandwidth. You can arrange by ports, source, destination, and also protocols, and also sight traffic patterns over minutes, days or months.

There’ s a range of predefined reports, as well as facilities to produce personalized reports, that procedure flow data into graphes and also tables showing how the network is being utilized and how that’ s changing gradually. You can set up records to be instantly run as well as provided. Predefined records such as “& ldquo; Typical and also Peak Web Traffic Rates –– WAN Interfaces Last 7 Days” & rdquo; reveal what valuable info can be acquired to assist bandwidth capability planning.
