An easy to use Windows solution that monitors and classifies bandwidth and network usage. The software supports SNMP, packet sniffing and netflow to generate live readings and trend data to optimize the efficiency of your network components.

It provides system administrators with live readings and long-term usage trends for their network devices. PRTG is mainly used for bandwidth usage monitoring, but may also be used to monitor many other aspects of a network such as memory and CPU utilization.

It allows you to get a clear view of the complex network, conduct Packet level Colasoft Capsa is a professional network analyzer aka.

By giving you insights into all of your network’s operations, Capsa makes it easy to isolate and solve network It captures reassembles and reorders TCP packets, performs IP Packet defragmentation and displays the tcp flow and trace timings. It is useful for logging network traffic in a ‘standard’ web server like or in a customized way.

It can log http response time, useful for tracking network services performances e. 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. By identifying traffic by application, category business vs. With a great user interface, this excellent packet sniffing software is perfect for network analysis. Get 30 Day Free Trial: www. It helps you manage your network and your servers. 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.

This makes it integrate with several ManageEngine products. The system is offered in two editions. The Essential edition gives you the standard network traffic monitoring functions plus a reporting and billing module. The higher plan is called the Enterprise Edition. You can get either edition of the NetFlow Analyzer on a day free trial.

LiveAction Omnipeek, previously a product of Savvius , is a network protocol analyzer that can be used to capture packets as well as produce protocol analysis of network traffic. Omnipeek can be extended by plug-ins.

However, the addition of the Capture Engine plug-in gets the packet capture function. The Capture Engine system picks up packets on a wired network; another extension, called Wifi Adapter adds wireless capabilities and enables Wifi packets to be captured through Omnipeek. The functions of the base Omnipeek Network Protocol Analyzer extend to network performance monitoring. As well as listing traffic by protocol, the software will measure the transfer speed and regularity of traffic, raising alerts if traffic slows down or trips passed boundary conditions set by the network administrator.

The traffic analyzer can track end-to-end transfer performance across an entire network, or just monitor each link. Other functions monitor interfaces, including incoming traffic arriving at web servers from outside the network.

The software is particularly interested in traffic throughput and a display of traffic per protocol. Data can be viewed as lists of protocols and their throughput or as live graphs and charts. Packets captured with the Capture Engine can be stored for analysis or replayed across the network for capacity testing. Riverbed is Wireshark’s primary sponsor and provides our funding.
