It also monitors the experience and network activity at every scope of magnitude, allowing you to discover problems quickly and easily find solutions.

It has more data sets than most people ever need to use along with the analytics to go with them. It allows you to take control of your network traffic on a micro level and predict and prevent future problems. It is also able to handle large files, so if you need to capture more than 2 gigs of data, this is your best bet.

It runs quickly and allows you to use your tools without programming command lines. If you have repeated network abuses, this is a good tool for you. The monitoring works very well, so you can look at specific end users and see exactly how they make use of the network.

EtherApe is unique because it is a graphical network performance monitor. This is an especially great option for visual people and for presenting network data to management. It is very clean and easy to use, with a UI as simple as their advanced network traffic analysis charts. The ability to get instantaneous feedback is really cool. With EtherApe, you can just use a managed switches monitoring port to watch your traffic flow in real time.

This network monitoring tool has a ton of great features, too. Nodes and link colors will show you what network protocols are being used most frequently. You can select the level you want to concentrate on, allowing you to fix a specific network protocol stack if it is especially problematic.

You can capture and collect your network data from a live connection then read it later thanks to tcpdump capture files. It supports a massive amount of frame and packet types, too! This system also allows you to customize your data displays using the pcap syntax in the network filters.

You can display your averages, your node persistent times, and more, and all of these are completely customizable so you can configure them however you want to. It will map your wireless networks then provide statistics and data about their performance, making it easy for you to troubleshoot any issues. KisMAC is a great tool for people who want to audit their networks and do performance monitoring. It excels at testing the security of your Wi-Fi connection. As a network performance manager, it is a great tool for managing your infrastructure and it can also monitor your network for you.

This tool focuses on monitoring, making it one of the most extensive options available for monitoring your network right down to the individual network devices that use it. It provides a perfect network monitoring service with a unified way to manage infrastructure. Businesses can have up to sensors for the free version, so it would be easy to conduct an evaluation.

You can monitor all of your routers, access points, switches, and could and software infrastructure easily. This includes services, storage, servers, and apps.

Even work stations can be added to the monitoring without making things too complicated. The tool went through a significant revamp in late This enhanced the performance and improved the user interface UI. The dashboard got a sleeker, user friendly look that offers displays and graphics for analytic symbols instead of the older version. This allows you to have more information without the clutter. It responds very well, too.

It has a great option to set alerts for anything that you are monitoring, so you will know the instant something deviates from the norm. It is also extremely flexible. Fiddler is a completely free web debugging proxy that is compatible with any platform, system, and browser. This allows you to trap undesirable network traffic between the Internet and your test computers so that you can inspect all of the data that is outgoing and incoming and monitor it.

It even offers an extremely powerful scripting subsystem that is based on events, so you can tweak it to do a lot of different things. You can even extend it by including. NET Framework language commands. This allows you to see anything you need to in order to debug your system. Fiddler can easily edit web sessions and record service requests and data. You can configure it so that it will decrypt everything or set it only to decrypt specific sections of the network.

You can troubleshoot JavaScript errors and see the entire page weight when it comes to caching HTTP and compressing it. It provides an infrastructure monitoring tool that is completely unified.

This will allow you to manage your network and servers easily. The Paessler Packet Capture tool can handle analyses of a lot of different functions. The packet sniffer will catch the headers of any network packets that come and go through your network, which makes it one of the fastest analysis tools on the market.

This also prevents the tool from taking up too much space when storing and holding capture files for you to use. The clean dashboard will categorize all your traffic by the type of application, including web packets, emails, chat app data, and the volume of any file transfers. Tcpdump is a bit of a beast. It is probably the least user friendly option available because it requires an in depth knowledge of TCP in order to work. The learning curve is very steep and intimidating enough that a lot of network administrators immediately dump it in favor of easier and more under friendly options.

Tcpdump allows you to learn about the network traffic on your machine. Tcpdump is an extremely accurate network picture that will offer you recording and instantaneous insight into your activity.

The tool also allows you to set a lot of custom flags and filters. You can easily filter the data that gets analyzed by IP address, Boolean queries, specific ports, or more!

The actions you take depend on your available budget. If you have the resources to expand network capacity, the packet sniffer will enable you to target new resources more effectively. If you have no budget, packet sniffing will help traffic shaping through prioritizing application traffic, resizing subnets, rescheduling heavy-traffic events, limiting bandwidth for specific applications, or replacing applications with more efficient alternatives.

It is important to understand how the network card on your computer operates when you install packet sniffing software.

In promiscuous mode, your NIC will pick up all network traffic. Most packet sniffers have a utility within the user interface that manages the mode switch for you. Network traffic analysis requires an understanding of how networking works.

Analysts should also have some understanding of the types of network traffic that exist on a normally functioning network such as ARP and DHCP traffic. While almost everything uses tcpdump at its core more on that later , enterprise-level tools can provide other analytical functions such as correlating traffic from many servers, providing intelligent query tools to spot issues, alerting on exception cases, and producing nice graphs that management demands.

Enterprise-level tools tend to focus on network traffic flow rather than judging packet content. By that, I mean that the focus of most sysadmins in an enterprise is to keep the network humming along without performance bottlenecks.

When bottlenecks occur, the goal is usually to determine if the problem is the network or an application on the network. On the other side of the coin, these enterprise-level tools are usually able to see so much traffic that they can help predict when a network segment will saturate which is a critical element of capacity management. Packet sniffers are also used by hackers. Be aware that these tools can be used to attack your network as well as to solve problems.

Invest in intrusion detection systems to protect your network from these forms of unauthorized access. The key feature of a packet sniffer is that it copies data as it travels across a network and makes it available for viewing. The sniffing device simply copies all of the data that it sees passing over a network. When implemented on a switch, settings of the device allow the passing packet to be sent to a second port as well as the intended destination, thus duplicating traffic.

Usually, the packets of data that are reaped from the network get copied to a file. Some tools will also show that data in a dashboard. However, packet sniffers can gather a lot of data, which includes encoded admin information. You will need to find an analysis tool that can help you be dereferencing information on the journey of the packets in the extract and other pieces of information, such as the relevance of the port numbers that the packets travel between.

A straightforward packet sniffer will copy over all of the packets traveling on the network. This can be a problem. If t cases, the contents of the packet are not needed for network performance analysis.

If you want to track network usage over a 24 hour period or over a few days, then storing every packet will occupy a very large amount of disk space — even if you are only taking in the packet headers.

In these scenarios, it is advisable to sample packets, which means copy every 10th or 20th packet rather than copying over every single one. They can also be used by more junior sysadmins to gain experience with how modern networks look during day-to-day operations, which will help identify network issues later on.

We reviewed the market for packet sniffers and analyzed the options based on the following criteria:. SolarWinds is a comprehensive suite of IT management tools. The tool that is more relevant to this article is the Deep Packet Inspection and Analysis tool. Collecting network traffic activity is relatively straightforward.

But not all situations are that cut and dried. In a bustling network, it may be hard to determine even some fundamental things such as:.

The contents of the packet are unknown to the network device. Deep Packet Inspection is different; it means that the actual contents of the packet are inspected to learn more about it. Critical network information that cannot be gleaned from the metadata can be discovered in this way. Tools like those provided by SolarWinds can provide more meaningful data than simply traffic flow.

Other techniques for managing high volume networks include NetFlow and sFlow. Each has its strengths and weaknesses and you can read more about NetFlow and sFlow techniques here. Network analysis, in general, is an advanced topic that is half experience and half training. SolarWinds Network Performance Monitor mode gives detailed insights into what causes network slowness and allows you to quickly resolve the root causes using deep packet inspection.

The network monitoring segment of the utility covers two types of tasks. These are a network performance monitor, which examines the statuses of network devices and a network bandwidth analyzer, which covers the flow of traffic over links in the network.

The bandwidth analysis part of PRTG is implemented through the use of four different packet capture tools. These are:. The PRTG packet sniffer only captures the headers of the packets traveling across your network.

This gives the packet analyzer a speed advantage and it also reduces the amount of storage space needed to hold capture files. The dashboard of the packet sniffer categorizes traffic by application type. These include email traffic, web packets, chat app traffic data, and file transfer packet volumes. NetFlow is a very widely used data flow messaging system. It was created by Cisco Systems but it is also used for equipment produced by other manufacturers.

The J-Flow method is a similar messaging system used by Juniper Networks for its equipment. The sFlow standard samples traffic flows, so it will collect every nth packet. NetFlow and J-Flow both capture continuous streams of packets. A sensor is a system condition or hardware component. The Paessler system includes many other network and server monitoring capabilities including a virtualization monitor and an application monitor.

PRTG can be installed on-premises or you can access it as a cloud service. The software runs on Windows environments and you can get it on a day free trial.

You can choose to sample traffic, capture entire streams, or gather statistics on traffic patterns with this tool. Thus, the NetFlow Analyzer is capable of using different languages to gather information. The monitor is able to track the consistency of data flows as well as the load on each network device.

Traffic analysis capabilities let you see packets as they pass through a device and capture them to file. This visibility will enable you to see which network applications are chewing up most of your bandwidth and take decisions over traffic shaping measures, such as priority queuing or throttling. The dashboard of the system features color-coded graphics, which make your task of spotting problems a lot easier. The attractive look and feel of the console ties in with other ManageEngine infrastructure monitoring tools because they were all built on a common platform.
