A program for limiting traffic. How to track traffic on the network. Comparison of the free software for accounting traffic NetWorx with the paid analogue DU Meter

Many network administrators often face problems that can be dealt with by analyzing network traffic. And here we are faced with such a concept as a traffic analyzer. So what is it?

NetFlow Analyzers and Collectors are tools that help you monitor and analyze network traffic data. Network process analyzers help you pinpoint the devices that are degrading bandwidth. They know how to find problem areas in your system, and improve the overall efficiency of the network.

The term " Netflow»Refers to a Cisco protocol for collecting IP traffic information and monitoring network traffic. NetFlow has been adopted as the standard protocol for streaming technologies.

NetFlow software collects and analyzes flow data generated by routers and presents it in a user-friendly format.

Several other network equipment vendors have their own protocols for monitoring and collecting data. For example, Juniper, another highly respected network device vendor, calls its protocol “ J-flow". HP and Fortinet use the term “ s-Flow".

Network Meter is a handy desktop gadget and traffic accounting software that allows you to easily control your Internet connection and distribute it over your local network and Wi-Fi. Most users ignore the features offered by desktop gadgets, which were already introduced in Windows Vista and carried over to Windows 7. Some of these applications can be very useful.

Network Meter is an application that monitors your active Internet connection. It allows you to specify an IP address both on the local network and on the Internet. Shows the current speed of data transfer, download, upload and the amount of data that we downloaded and sent during the last session (since Windows reboot). In addition, in wireless monitoring mode, the app shows the SSID Wi-Fi networks, that is, its name and the percentage value of the signal quality (0 - 100%). An additional element of the gadget is an IP address locator (IP lookup) and an Internet tester (speed test).

Anyone can use the program:

Unpack the gadget installer from the ZIP archive, choosing a location on your hard drive. Double click the unzipped file to install Network Meter.
You will be prompted to check the manufacturer, click Install. The gadget should appear on our desktop (usually on the right), but you can place it anywhere by grabbing and dragging with the left mouse button.
The app is already active, but to make sure it is tracking the connection you are interested in, go to the "Network Meter" option. To do this, right-click on the gadget and select "Options".
On the main tab "Parameters" you can control the functions of the gadget. First of all, you need to choose which network to monitor (network type). You can choose to connect to your local area network via cable (wired) or Wi-Fi (wireless). In the latter case, the gadget will be equipped with additional functions - SSID and signal quality meter. The function indicated by the marker shows the network card controlled by our local IP address (LAN) as well as the network controlled for data transmission. If used on a personal PC, there will be no problem, but on a laptop it is worth making sure that All Network Meter is currently monitoring the active card - usually you have to choose between Ethernet LAN and Wi-Fi card.
The Display tab determines how the gadget displays information. For example, it is recommended that you change the default units setting from bits per second to find the speed in kilobytes or megabits. The settings are saved by pressing the "OK" button.
Changes in the "Network Meter" window appear immediately. It is worth noting that the counter represents the current data transfer - at the moment and thus monitors network activity. However, another metric counts how much data is downloaded and sent during that session. It can be useful for users using limited networks - for example, 3G mobile internet. This makes it easy to know if the packet is being exceeded.

"10-Strike: Traffic Accounting" is a simple program for monitoring traffic consumption on computers, switches, servers on the network at the enterprise and even at home (3 sensors can be monitored for free in the trial version, even after the expiration of the 30-day trial period). Monitor volumes incoming and outgoing consumed traffic on the PC of your entire local network, incl. when accessing the Internet.

The software constantly collects statistics from hosts on the volume of incoming and outgoing data and displays in real time the dynamics of changes in the data transfer rate on network interfaces in the form of graphs and tables.

Detect unscrupulous users who consume a lot of Internet traffic in your organization. Violation labor discipline staff leads to decrease in labor productivity... The simplest analysis of traffic consumption by employees' computers will reveal the most active network users. When using WMI sensors, you don't even need to install anything on the network PC, you just need an administrator password.

Unfortunately, in our country, Internet traffic for legal entities cheap. It often happens that excessive Internet activity of users (often not related to the workflow) leads to cost overruns organizations to pay for the connection. Using the software will help prevent your business from receiving unexpectedly high Internet bills. Customize notification for the consumption of a certain amount of traffic computers of the enterprise for a certain period of time.

You can observe graphs of the speed of incoming and outgoing traffic PC and network devices on the screen in real time. You can quickly determine who spends the most and clogs the channel.

The program constantly monitors the traffic consumption on the PC and can notify you when certain conditions are met which you can ask. For example, if the amount of consumed traffic by any PC exceeds a predetermined value, or the average information transfer rate for a certain period is higher / lower than the threshold value. When the specified condition is met, the program notify you in one of the following ways:

displaying a message on the computer screen;
sound signal;
sending e-mail messages;
writing to a log file;
recording in the Event Log of the system.

In addition, the program can to execute certain actions when the conditions are met: launch another program, execute a VB or JS script, restart the service, restart the PC, etc.

As the software runs accumulates statistics of traffic consumption computers. You can find out at any time who received the data and how much at any given time, what data transfer rates were achieved. Data download speed graphs, as well as tables of traffic volume consumption, can be built for any period of time or date.
