In this review, we'll discuss and compare two of the most popular network monitoring solutions, WireShark and Paessler PRTG. Wireshark OverviewPaessler PRTG overviewUser interfacesKey featuresCustomer supportPricingConclusion No organization can function without a robust and reliable IT network in today's always-on business world. As a result, organizations require a powerful network monitoring solution in place. Network monitoring tools allow you to track your network usage, identify bottlenecks, and troubleshoot problems quickly and efficiently. By proactively monitoring your network, you can avoid disruptions in services and keep your business running smoothly. Wireshark overview Wireshark is an open-source packet analyzer. Network administrators use it to troubleshoot network issues, and security professionals monitor network traffic for signs of intrusion. You can use Wireshark to capture live data from networks, including Ethernet, Bluetooth, and Token Ring. Wireshark Main Interface (Source) Wireshark works by capturing packets of data that are being transmitted over a network. These packets are then displayed in a human-readable format to be analyzed. Each packet that Wireshark captures contains a wealth of information. This information includes the packet's time stamp, source and destination, the type of packet, and much more. Captured data can be analyzed and filtered to display only the most relevant information. This allows network administrators to quickly identify and resolve problems in their networks. Security professionals can use Wireshark to monitor network traffic for signs of malicious activity, such as denial-of-service attacks, SYN floods, and other attacks. All of this information can be extremely helpful in troubleshooting or understanding how a network or particular device functions. Equipped with this information, you can quickly identify and fix networking issues. Paessler PRTG overview Paessler PRTG is an all-in-one monitoring solution for networks of all sizes. With it, you can monitor your entire infrastructure, from servers and switches to applications and databases. Paessler PRTG gives you a single-pane view of your network, so you can spot problems early and prevent them from becoming major incidents. Paessler PRTG Interface (Source) Paessler PRTG works by constantly polling the devices on your network and collecting data about their performance. This data is then visualized in graphs and tables, so you can quickly see which devices are healthy and which need attention. Paessler PRTG also sends alerts when it detects problems so that you can take corrective action immediately. It has over 200 built-in sensors for standard devices like Windows servers, Linux servers, routers, and switches. These sensors track everything from CPU and memory usage to disk space and traffic analysis. And if you need to monitor a custom device or application, Paessler PRTG offers custom sensors that give you the flexibility to do just that. Paessler PRTG provides all the data you need to ensure your network runs smoothly. By identifying potential problems early, it helps you avoid significant outages and keep your business up and running at all times. Wireshark vs. Paessler PRTG: A comparison User interface Wireshark's user interface is divided into three main panes: the packet list pane, the packet detail pane, and the packet bytes pane. The packet list pane shows a list of all the packets that Wireshark has captured. You can use the various display filters to limit the list to only the packets that you're interested in. For example, you can filter by protocol, source IP address, destination port, etc. The packet detail pane shows the currently selected packet in the packet list pane. This includes information such as the protocol headers, hex dump of the data payload, and decoded fields for specific protocols such as HTTP. The packet bytes pane shows a hex dump of the data payload for the currently selected packet. This can be useful for low-level troubleshooting or looking for specific data strings. By dividing the UI into three panes, Wireshark makes it easy to view relevant information for each packet while still providing access to all of the packets that have been captured. And with various display filters, you can customize your experience only to show the information you're interested in seeing. Whether you're a seasoned network engineer or a novice just getting started, Wireshark's user interface has something to offer everyone. One of the first things you'll notice about the user interface of Paessler PRTG is its easy use. Everything is laid out intuitively and logically. The main screen shows you an overview of your entire network at a glance, and from there, you can drill down into specific devices and sensors to get more detailed information. Even if you've never used a network monitoring tool before, you'll be able to get up and running with Paessler PRTG in no time. In addition to being easy to use, the user interface of Paessler PRTG is compelling and flexible. It includes a wide range of features and options that allow you to customize the tool to fit your needs. For example, you can create customized dashboards to display the most crucial information, set up alerts so you're notified immediately when something goes wrong, and generate reports on demand or on a schedule. Whether you're looking for a more straightforward way to monitor your small network or need an enterprise-level solution for your business, Paessler PRTG has you covered.
