NetTraffic: Монитор сетевого трафика в режиме реального времени для Windows

NetTraffic — бесплатный монитор сетевого трафика в режиме реального времени для Windows 8 | 7. Не просто полезно, NetTraffic прост в использовании и предлагает множество настроек. Он создает графики в реальном времени и показывает статистику, которая обновляется каждую секунду. С помощью этого удивительного инструмента вы можете легко контролировать свою сеть.

Монитор сетевого трафика в режиме реального времени

После загрузки NetTraffic вы можете просто запустить его без каких-либо установок. Он начнется с системного трея, а когда вы нажмете значок NetTraffic из панели задач, отобразится небольшое окно, отображающее графики трафика в реальном времени.

Три графика отображаются одновременно — скорость загрузки, скорость загрузки и общее количество. Эта небольшая диаграмма дает вам четкое представление о сетевой ситуации на вашем компьютере. Если вы не видите это окно препятствием на экране вашего компьютера, вы можете привязать его к экрану, как виджет, который отображается все время. Но если вы хотите, вы можете скрыть это окно, когда захотите.

Еще одна удивительная особенность этого программного обеспечения — это числовое число в реальном времени Статистика, Вы можете открыть статистику из контекстного меню. Статистика отображает различные полезные сведения и продолжает обновлять их в режиме реального времени. Есть четыре счетчика из которых каждый сбрасывается каждый час, второй сбрасывается каждый день, третий сбрасывается каждый месяц и, наконец, четвертый сбрасывается каждый год.

Кроме статистики, NetTraffic также может наращивать Графики и таблицы отображение данных полосы пропускания. Графики хорошо построены и полностью различимы.

С NetTraffic вы даже можете экспортировать или импортировать данные, сгенерированные программой, и для нового запуска вы можете даже сбросить все счетчики. Программное обеспечение настраивается в очень большой степени.

По умолчанию он начинается с Windows, но если вы хотите, вы можете изменить этот параметр. Интервал обновления по умолчанию составляет 1000 мс, но его также можно изменить на пользовательское значение. Из настроек вы можете выбрать сетевые интерфейсы, которые необходимо контролировать, иначе вы можете щелкнуть флажок «Использовать все интерфейсы», чтобы контролировать все доступные сетевые интерфейсы.

Если мы поговорим о внешний вид диаграммы, вы можете выбрать прозрачность диаграммы и, кроме того, вы можете изменить цвет различных компонентов диаграммы. Вы можете изменить цвета фона и даже единицы измерения скорости. Доступны два типа диаграмм, которые являются строковыми и гистограммами, вы можете выбрать любой из них из настроек.

NetTraffic — хорошая утилита мониторинга сети с полезными функциями и достойным интерфейсом. Некоторые функции уникальны и очень необычны — и в целом бесплатное программное обеспечение должно быть.

How to Monitor Network Traffic

Nick Congleton

It might seem a little too tech-y or excessive, spying on all the traffic going through your home network, but it can help provide valuable insights into your network’s performance.

You’ll uncover exactly which devices, or even specific programs, are hogging your bandwidth. Through network monitoring, you can uncover where you computers are connecting and how much data they’re sending or receiving. Then, you’ll be able to correct any problems and make better use of your network.

There are plenty of ways that you can monitor your network. The three detailed here are probably the most common and convenient.

Using Your Router

Everyone has a router, and you can access it from nearly any device on your network. All your traffic already flows through the router, so it’s the most direct source of information about what’s going on within the network.

You’re going to need to find out your router’s IP address. For most routers it’s 192.168.1.1, unless someone changed it. If you’r not sure, open a command prompt, and run ipconfig. On Mac and Linux, run ip r. On Windows, you’ll find your router’s IP listed as the Gateway. On Linux, it’ll be next to default via.

Use ipconfig to find your router IP on Windows

Open your web browser and enter the router’s IP address in the address bar. This is exactly like browsing to a website, so press Enter after you enter the IP address.

IP address typed in browser

You’ll probably be prompted to enter your router’s admin username and password before you can go any further. If you didn’t set them yourself, your ISP probably did when the set it up. Look for any documentation they may have provided to sign in.

Every router is different, and so are their interfaces. When you first sign in to most, you’ll arrive at a basic status page. It’ll show you information about your router and your network that may be useful, but not too in-depth. Try to find a Device List link to see which devices are connected to the network.

Router overview page

Your router’s device list will show you the IP addresses of the devices connected to the network. It may even provide a bit of information about what they are. You will usually see a computer’s name next to the IP, if one was set. Here, you’ll also be able to see connection information for Wi-Fi devices, including their signal quality and the available bandwidth.

Router device list page

Have a look around for a Status section on your router. You might be lucky enough to even have a specific Bandwidth or Network Monitoring section. It’s under a section like this that you’ll be able to find more data about bandwidth usage of specific devices by IP address.

When you locate your router’s traffic or bandwidth monitoring sections, you’ll be able to see which devices are using the most bandwidth. You’ll see transmission rates and other useful stats. In some cases, you may find graphs and even real-time monitoring that provide visualization of what’s happening on your network.

Router IP traffic monitoring graph

With this information, you’ll be able to find out what your networks biggest hogs are and what devices might be struggling to get a decent signal. You’ll also be able to see if anyone’s weaseled their way onto your network when they shouldn’t be there.

Wireshark

Wireshark is an open-source tool for packet filtering. If you don’t know what packet filtering is, it’s a much lower level network management task, so Wireshark can be considered overkill for simply viewing traffic on your network. That said, it can absolutely get the job done. Plus, it’s free and available for Windows, Mac, and Linux.

Open your browser and head to the Wireshark download page, and grab the latest installer for your operating system.

If you’re on Linux, Wireshark is probably in your distribution’s repositories. Ubuntu and Debian users should install Wireshark with:

Run the Wireshark installer. Everything should be straightforward, and the default options will work in almost every case.

Open up Wireshark

Wireshark running on Linux

If Wireshark looks confusing at first, don’t worry. You don’t need to know much about it for the basics. Select Edit and Preferences in the top menu to set one option that you’ll need.

A new window will open up. Locate Capture in the left side list and select it.

Wireshark capture preferences

The body of the window will shift to display the capture options. Make sure that Capture packets in promiscuous mode is checked. Press Ok when it is.

Using Wireshark in promiscuous mode on a network that you don’t own is not legal. Be sure to only do this on your own network.

Back on the main Wireshark window, there are two icons that you’ll need in the main menu. The blue Shark Fin icon starts the Wireshark capture process that records network activity. The red Square stops the capture. You’ll be able to review and even save the data after the capture. Press the Fin to start.

Let the capture run for a bit. If there’s something that you’ve been having a problem with on your network, try to recreate those circumstances. With any luck, Wireshark will capture the moment the problem occurs, and you’ll be able to take a look at what happened.

Wireshark capture results

After you’re satisfied with the amount of info you collected, press the red Square to stop the capture.

Take a look at the results. In the top section of the window, you’ll see the different packets collected by Wireshark. Each one will have an IP address that sent the packet and one that received it. You’ll also see the network protocol of each. When you select one, you’ll be able to sift through the packet data in the box below. The lowest option on the list generally contains the most “human readable” portion of information. If the packet was encrypted, though, you won’t see much.

Keep looking through. Try to use the timestamps to locate the exact moment that your problem occurred. Hopefully, there will be relevant information available. If you want to know more about Wireshark, check out the complete Wireshark tutorial.

  • What is network traffic?
  • What is network traffic?

Network traffic, also called traffic or data traffic, refers to the data moving across a network at any given time. Network data consists of packets, the smallest, fundamental units of data passed along a network. Network traffic data is broken into these packets for transmission and reassembled at the destination. Packets consist of payloads (the raw data) and headers (the metadata) containing information like origin and destination IP addresses.

There are four broad categories of network traffic:

  1. Busy/heavy traffic, where high bandwidth is consumed
  2. Non-real-time traffic, which refers to the bandwidth consumed during working hours
  3. Interactive traffic, traffic facing competition for bandwidth, which results in slow response times if prioritizations for traffic and applications aren’t set
  4. Latency-sensitive traffic, which can also result in poor response times due to competition for bandwidth

Gaining insights into network traffic is important when managing and measuring bandwidth (the amount of data that can be transmitted in a set amount of time) and maintaining functional bandwidth is critical to service delivery.

Analyzing your network traffic can have many benefits. It can help identify network bottlenecks, which occur when there isn’t enough data handling capacity to manage the volume of traffic currently passing through. It can also help what identify users or applications are the network top talkers. This analysis has security benefits as well, since an unusually high amount of traffic in a network can indicate a cyberattack.

Analyzing network traffic can also provide insights into current and past bandwidth usage patterns, allowing you to better understand your organization’s future network needs. By measuring the amounts and types of data traveling across the network, admins can better manage it to make sure the most important processes receive the required bandwidth.

Here are some basic steps required to manually check network traffic through a router:

  • Access your router by entering your router’s IP address into a web browser.
  • Once you sign in, look for a Status section on the router (you might even have a Bandwidth or Network Monitor section depending on the type of router).
  • From there, you should be able to see the IP addresses of devices connected to your network.
  • For most modern routers, you should be able to click through on a device level and overall network to see traffic activity.

For any organization, knowing the number of connected devices and their usage is a good first step in understanding the potential bandwidth requirements needed to support the amount of traffic on a network. However, this surface-level traffic data often doesn’t support the ability to see or act on this information at scale for devices across your environment.

The best way to check network traffic is with a tool like SolarWinds ® Bandwidth Analyzer Pack (BAP). BAP is built to automatically check and compile network traffic insights from devices across your network in a centralized dashboard and alert you to any concerning behavior in your network.

The first step in monitoring network traffic activity is to understand what you’d like to monitor or the issue you’re trying to solve. This includes monitoring traffic to servers, firewalls, or other devices on your network or for a specific issue like bandwidth usage or packet loss. By first identifying the goal of the monitoring, you can limit your focus to the most important metrics to your analysis and the best tools to use to perform this troubleshooting.

For example, monitoring traffic activity at the packet level can help you understand how packets travel between devices to ensure your services are being delivered. Monitoring the traffic activity between network devices can also provide insights into whether packets are being lost due to insufficient bandwidth. Using commands like tracert can provide some visibility into packets, but a packet sniffer, also called a network analyzer or a protocol analyzer, is built to intercept, log, and analyze network traffic and data. Insights into packet origin and destination, dropped packets, fluctuations in packet traffic, and similar data points can signal issues and help admins pinpoint the location of network activity issues.

While a sniffer can provide packet-level insights, only a network activity monitoring solution is designed to help you answer the question of whether network traffic levels normal for your infrastructure. Beyond simply monitoring network traffic, it’s important to have a network traffic monitoring tool to measure traffic and provide detailed analysis, allowing you to implement policy changes and maximize your bandwidth capabilities.

The network traffic monitor tool in SolarWinds BAP is designed to help you identify network traffic issues with ease, so you can improve your bandwidth capabilities to ensure good performance for end users.

SolarWinds BAP is built to monitor how traffic moves between devices and if the end-user experience is affected via packet metadata to calculate application and network response time in addition to having the ability to compare past and current levels of network traffic to highlight trends. The PerfStack ™ feature streamlines root cause identification with the option to correlate performance metrics on a drag-and-drop timeline. For admins who can’t be at their dashboard 24/7, BAP supports advanced network alerting. Use simple or complex trigger conditions to set automated alerts with the details you need to help speed troubleshooting, then configure those alerts to send to the admins of your choice.

Мониторинг сетевого трафика в Windows 10, 8.1, 7 с помощью Microsoft Network Monitor

Сетевой монитор MS не обнаружит сетевые адаптеры вашего компьютера после установки

Советы и хитрости

Сетевой монитор Microsoft — устаревший инструмент, который может анализировать сетевой трафик и пакеты на ПК с ОС Windows. Он больше не получает поддержки от Microsoft, но доступен для загрузки в виде заархивированной версии. В этом руководстве я покажу, где скачать и как отслеживать сетевой трафик в Windows 10 / 8.1 с помощью Microsoft Network Monitor.

Вместо того, чтобы использовать другие бесплатные или платные инструменты для мониторинга сетевого трафика, рекомендуется использовать этот продукт с операционными системами MS, поскольку они оба принадлежат одному поставщику.

Иногда для любого домашнего / рабочего конечного пользователя очень полезно проверить активность своего компьютера в сети и узнать, что происходит с сетевым трафиком. Этот инструмент может захватывать, анализировать и отображать пакеты сетевого трафика в понятном формате. Это помогает диагностировать и устранять проблемы, связанные с сетью, на компьютере с Windows 10.

Шаги по мониторингу сетевого трафика в Windows 10

1) Скачайте MS Network Monitor с официального сайта. (Загрузите правильную версию для ОС, 32-разрядную или 64-разрядную). Хотя ОС Windows 10 не указана в списке поддерживаемых ОС, но работает хорошо.

2) Установите программу. Сетевой монитор MS не обнаружит сетевые адаптеры вашего компьютера после установки. Вам нужно выйти и снова войти, чтобы он работал.

3) После того, как сетевые адаптеры будут перечислены в левом нижнем углу, нажмите «Новый захват». Вы можете открыть ранее сохранённый файл захвата, чтобы продолжить предыдущую работу.

После того, как сетевые адаптеры будут перечислены в левом нижнем углу, нажмите «Новый захват»

4) Нажмите Старт, чтобы начать захват пакетов. Это начнёт захватывать все исходящие и входящие сетевые пакеты на ноутбуках или настольных компьютерах с Windows 10. Все подробности будут показаны в разделе «Сводка кадров».

Нажмите Старт, чтобы начать захват пакетов

Вы можете просмотреть программы, использующие сетевой трафик, в разделе «Сетевые преобразования».

5) Щёлкните программу, которую хотите отслеживать отдельно. Например, если вы нажмёте Chrome browser exe, вы сможете просмотреть его сетевую активность в разделе «Обзор кадров».

6) Ещё одна полезная функция — фильтрация. Вы можете легко выбрать тип сетевых пакетов, которые хотите отслеживать на компьютере с Windows 10/7. Например, если вам нужно отслеживать входящий и исходящий трафик, связанный с DNS, вы можете применить фильтр и просматривать только релевантную информацию.

Чтобы включить фильтрацию в сетевом мониторе Microsoft, нажмите кнопку раскрывающегося списка «Загрузить фильтры» в разделе «Фильтр отображения». Стандартные фильтры доступны в разделе Стандартные фильтры. Выберите нужный тип и нажмите Применить. Кроме того, вы можете редактировать их и сохранять под разными именами по вашему выбору.

Вы можете легко выбрать тип сетевых пакетов, которые хотите отслеживать на компьютере с Windows

7) Не забудьте нажать кнопку «Автопрокрутка» под Сводкой кадров, чтобы просмотреть активность без прокрутки. Это автоматически прокрутит окно и перенесёт вас к недавнему событию.

Не забудьте нажать кнопку «Автопрокрутка» под Сводкой кадров

Заключение

Это некоторые из основных задач, которые вы можете выполнять с помощью инструмента Network Monitor. Он имеет несколько более сложных и полезных функций, которые могут использоваться сетевыми и системными администраторами для расширенного устранения неполадок.

Поскольку Microsoft прекратила разработку этого инструмента, вы должны искать альтернативный инструмент. Который регулярно получает больше функций и обновлений. Wireshark — один из лучших и бесплатных инструментов для мониторинга сетевого трафика в ОС Windows 10 / 8.1. Несмотря на то, что инструмент MS Network Monitor 3.4 довольно старый, вы можете использовать его в операционных системах Windows server, таких как 2012 R2, 2016 и Windows 2019, для анализа входящих и исходящих сетевых пакетов.
