The way business is conducted worldwide has changed dramatically over the past decade, primarily due to the constant improvements and innovations in technology. The significant advances in business specific technology have catapulted ecommerce and innovative interdepartmental cohesion into the forefront of the vast majority of businesses, both in the public and private sectors. Equipped with hardware and software that didn’t even exist a decade ago, companies big and small are increasing productivity, efficiency, and cost control to previously unfathomable levels, which enables these companies to perform better than ever before. The use of Servers, computers, websites, domain names, and the like have enabled companies to achieve far more in far less time, but with these advances also come the potential for new pitfalls. These pitfalls are addressed almost universally by the formation of IT departments in nearly every company to ensure the technology that is aiding the company does not malfunction and therefore cripple productivity. These IT departments are comprised of highly specialized and certified experts who not merely repair malfunctions, but also ensure that the company gains the most out of the highly expensive equipment. This is achieved by the assembling of a highly complex infrastructure of computers and equipment that work together to streamline and expedite the necessary tasks of a business, as well as to simplify the once elusive goal of multiple departments being able to communicate, share work, and multitask with one another. This is where monitoring network software becomes integral, as it is perhaps the most important aspect in proactively preventing system failures and malfunctions, as well as to avoid data loss and unauthorized access by any number of malicious entities who would purposely damage, destroy, or steal a company’s vital data. As companies transition into the world of servers and email and intra-office networks they become dependent on the technology and equipment that powers these contemporary marvels, and as a result productivity can be diminished or brought to a grinding halt when these systems malfunction. To prevent setbacks such as these IT departments and vendors have developed various safeguards and protections, perhaps the most effective being monitoring network software. This term and technique goes far beyond merely observing a server and the network it powers, monitoring network software is essential to any company that relies on servers, networks, and technology to streamline their day to day operations. Reducing Stoppages: Monitoring Network Software Keeps Everything Running Smoothly. Every technological advance brings the potential for more and complex problems in turn, making the very equipment that bolsters a company equally capable of slowing it down. A network is the linking up of 2 or more computers for the purpose of sharing data, speeding up communications and increasing interdepartmental functionality. These networks are often complex systems that are capable of linking the efforts of not just multiple computers, but multiple departments and locations as well. The servers responsible for ensuring networks run seamlessly are sophisticated computers that require far more maintenance and attention than a single desktop or laptop, and to carry out their function they are equipped with intricate programming, or software. Monitoring network software combines two different critical aspects that address both components of a network; meaning that it not only ensures the equipment, or hardware, which enables a network works properly, but also ensures that the programming, or software does so as well. Monitoring network software can involve both aspects at once, as the software detects any glitches or bugs in the programming and in the server computer at the same time. Therefore, monitoring network software encompasses two different areas, namely the network and the equipment that forms it. Server monitoring is hardware specific, it evaluates the performance of each individual machine that makes up a network and can detect when a single machine’s components are malfunctioning, which though confined to one computer can often have undesirable effects on the entire network. Network monitoring is the assessment of the programs that are used in a network, both on each individual computer and in the server as well. Monitoring network software has progressed as rapidly as the technology that it supports to the degree that there now exists powerful programming that performs both hardware and software protection and problem prevention in the same mode. The rapid development of monitoring network software now addresses system optimization, the prevention of unauthorized access, smooth operation throughout the network and the successful transmission of data from one machine to the next, making it just as integral as the system that it maintains.

On the dashboard, you’ll be able to view the health and performance data of your entire network. Here, devices will be characterized as Up , Warning , Critical , or Undefined . You can also use SolarWinds Network Performance Monitor’s wireless monitoring to view the performance of your wireless connection as well. Most notable is the ability to build wireless heat maps to see where your local connection is strongest. Of course, if you find that you want more depth over your network’s structure then you can view intelligent maps of your entire environment. With intelligent maps, you can see how connected devices interlink and see when they are experiencing performance issues. In the event that you aren’t at your desk to catch an event then you can stay in the loop with notifications via email and SMS . For those organizations who are looking for an easy-to-use LAN monitoring tool that can monitor their entire local environment, SolarWinds Network Performance Monitor is the perfect package. SolarWinds Network Performance Monitor starts at a price of £2,275 ($2,926). There is also a free trial. 2. ManageEngine OpManager (FREE TRIAL) Going back to the traditional dashboard monitoring experience we have ManageEngine OpManager . It provides an aesthetic LAN monitoring experience on Windows and Linux that allows the user to monitor the real-time and historical usage of data. Metrics you can monitor with ManageEngine OpManager included CPU usage , availability , disk space , and memory utilization on physical and virtual elements. With ManageEngine OpManager , the onboarding process is simple. This tool takes less than two minutes to set up in order to start monitoring your network. From then on you can start to configure your own alerts to keep track of network events. Alerts are threshold-based so that you only receive notifications once a device’s usage has exceeded a preconfigured threshold. For those instances where you need to collect further information about your network usage, there is a reports feature. ManageEngine OpManager comes with more than 100 built-in reports that you can customize or schedule as you wish. These are useful for preparing you for regulatory compliance or even keeping your team up-to-date. There are two main versions of ManageEngine OpManager available for purchase: the Essential version and the Enterprise version. For 25 devices ManageEngine OpManager costs £555 ($715). The Essential version is available for 500 devices at a price of £15,395 ($19,795). You can download the free trial . 3. Paessler PRTG Network Monitor. Another leading LAN monitoring tool is Paessler’s PRTG Network Monitor . It offers a network monitoring experience that is built around sensors. With this tool, you can easily monitor connected hardware, applications, cloud services, webpages, and NetFlow data to scrutinize the performance of the network. PRTG Network Monitor is great for those enterprises who want to get a quick start on their network monitoring because it offers an autodiscovery feature. With network auto-discovery, PRTG Network Monitor automatically scans your network and locates connected devices. Once a device has been found, PRTG Network Monitor will create a sensor to monitor it. In PRTG Network Monitor , sensors are designed to track the performance of network elements in a segmented manner. For example, there are sensors for bandwidth monitoring, web servers, SNMP, Windows, Linux, and virtual servers. Sensors help the user to narrow down to specific network performance issues without getting lost in other data. Although PRTG Network Monitor emphasizes sensors, it still has threshold-based alerts through email and SMS so that you don’t miss out on anything important. If you’re part of an organization that’s looking for an affordable network monitoring tool then PRTG Network Monitor is a solid product.

When it comes to advanced network monitoring, Dynatrace has developed a reputation as an essential cloud-monitoring tool. Dynatrace is an application performance management and cloud infrastructure monitoring system. In other words, this tool provides you with “full stack” visibility throughout your local environment. The automation of Dynatrace is one of the main reasons it has acquired such a popular following. To use Dynatrace all you need to do is install one agent per host , then the program will start to collect metrics throughout your network stack. Similarly, there is an autodiscovery feature that discovers and maps devices so that you can view the relationships between them. The responsiveness of Dynatrace to the latest threats is another reason to buy. The user is sent alerts the moment a security event occurs. The platform also activates root cause analysis to provide the user with details as to the cause of the security incident. In some instances, you can even automate the response so that Dynatrace solves the problem itself. Dynatrace is an exceptional choice for those organizations that want to automate their LAN monitoring efforts. In order to find out more information about the pricing options for Dynatrace you’ll need to contact the company directly. However, there is a free trial . 5. Zabbix. Zabbix is an open source network monitoring tool that provides everything you need to monitor your local environment. Zabbix offers network monitoring, server monitoring, cloud monitoring, application monitoring, and services monitoring to provide 360-degree protection against threats and poor performance. The effectiveness of this approach has lead Zabbix to be adopted by such household names such as Dell and Salesforce. Perhaps the greatest strength of Zabbix is its ability to detect network problems almost immediately. Zabbix offers trend prediction , anomaly detection , and problem forecasting . The most interesting of these three is the anomaly detection feature which can detect anomalous activity in your network, notify you, and start root cause analysis to pinpoint what caused the problem. However, if you want to use that more dashboard-based approach Zabbix has plenty onboard to support you. Network usage is displayed with clear visualization options such as graphs and a central dashboard to minimize the risk of missing something important. You can even generate reports if you wish to compile more information on a recent event. The best part about Zabbix is that it is completely free for CentOS , Debian , Oracle Linux , Red Hat Enterprise Linux , Ubuntu , and Raspbian . As such, this makes it suitable for organizations on a shoestring budget who are looking for an open source approach to LAN Monitoring. You can download Zabbix for free. 6. Pandora FMS.

WhatsUp Gold is another top-of-the-range web-based LAN monitoring tool that provides one of the best dashboard-based experiences on the market. When monitoring your network with WhatsUp Gold you’ll notice that the dashboard doesn’t overwhelm you with information. You can view the status of network devices through the Current Device Status screen (here you are shown whether devices are categorized as Up, Down, Maintenance, or Unknown with colored blocks). To make things convenient, WhatsUp Gold also has an autodiscovery feature which automatically discovers connected devices so that they can be monitored immediately. Autodiscovery not only connects devices but helps to form a map of the entire network. The map view is particularly useful when it comes to troubleshooting problems in particular areas of a network. The alerts system doesn’t miss a step either, with customizable alerts that are triggered the moment a network event occurs. Alerts can be sent via email , SMS , slack , web alarms , IFTTT posts , or service restarts . No matter what threat you are confronted with, WhatsUp Gold puts you in the best position to be responsive under pressure. WhatsUp Gold is available in a number of editions: Premium Annual Subscription , Premium License , and the Total Plus License . The main version between the Premium and Total Plus versions is that the Total Plus version provides you with network traffic analysis, application monitoring, virtualization monitoring, configuration management, and scalability pollers. Pricing for WhatsUp Gold starts at £2,065 ($2,656). There is also a free trial. 10. Zenoss Core. Finally we have Zenoss Core . Zenoss Core is a free network monitoring platform that offers application performance management , log data , events data , and incident management . The APM focus of Zenoss Core has made it ideal for monitoring both physical and virtual devices (including containers and microservices). Zenoss Core is available for Linux but can also be installed via VMware Player or VMware Server by users on Windows and Mac devices. However, much of your monitoring activity will take place through the online web-based GUI. The dashboard is completely customizable so that you can drag and drop widgets as you see fit. In terms of visualization, Zenoss Core is a little outdated when compared to many other tools on this list. That being said it does provide you with everything you need to stay up-to-date. Device Status is color-coded so that you can check the uptime of devices instantly. You can also view a color-coded network topology map that shows all of your connected devices. There are three versions of Zenoss available: Zenoss Cloud , Zenoss On Premises and Zenoss Core . Zenoss Core is the free community version and offers basic network monitoring capabilities. However, if you require more advanced features like event management, root-cause analysis, analytics, and reports, you’ll need to purchase Zenoss Cloud or Zenoss On Premises. You can download Zenoss Core here. Best LAN Monitoring Tools: SolarWinds Network Performance Monitor and Dynatrace.
