10 Network Performance Monitoring (NPM) Tools You Shouldn’t Miss

on June 3, 2020

Network performance monitoring is a continuous process of measuring, monitoring, and optimizing the performance of your network with the help of performance monitoring tools, often using varied types of telemetry like.

Simple network management protocol gives an organization using network monitoring tools the ability to quickly identify the devices connected to the network, monitor the performance of the network, keep track of changes to the network, or determine the status of network devices on a real-time basis.

Another type of telemetry is the network flow data containing protocols, like NetFlow and jFlow. It can also be labelled as a digital record with information about the connections made over a network by keeping track of details like the source and endpoint IP address, the duration of communication between them, how often the communication takes place, and its duration.

A different form of telemetry network performance tools employ is network packets carrying the data around as packets on a network. Capturing these packets help diagnose and solve network challenges, including assessing a cloud application, planning a migration to the cloud, or network capacity planning.

The Importance of Network Performance Monitoring

Since businesses today rely on a strong and secure network to run their operations and deliver a smooth and user-friendly experience to their customers, monitoring becomes extremely important, and any deterioration in the quality of your network performance impacts business. Businesses of all sizes need a performance monitoring tool to help them monitor problems, anticipate potential disruptions, and address them beforehand. Continuous network monitoring helps them maintain a congestion-free network up and running.

Organizations can also gain an immediate ROI with the right set of network performance tools, as the IT team can focus more on the more critical tasks rather than manually digging and checking on the network performance. Having a network performance tool at their disposal also helps organizations meet their service level agreements concerning network availability, thereby ensuring a satisfied client base. Network performance tools also help validate whether there is a need to upgrade servers by looking at the historical records of your server performance.

Benefits of Network Performance Monitoring Tools

Good customer experience is quintessential for companies, and this also becomes the prime reason to monitor network performance. A network performance tool helps identify slow-performing devices along with findings of such poor performance. These tools focus on the start and end of the data path, focusing on each network node to examine the performance at every point on the network. It also helps monitor the data transfer rate at every signal node and single out devices with poor performance.

Apart from issue identification, a good tool also helps ensure continuous uptime, prevent outages, and detect and troubleshoot CPU and server bottlenecks like utilization, speed, and idle time. Moreover, a good performance monitoring tool allows you to identify bandwidth hogs early on, enabling improved performance. A fully loaded performance monitoring tool also helps monitor and reduce packet loss due to errors and discards indicative of a problem with the switch or the device interacting with the switch. A network performance monitoring tool can also help you monitor your WAN connections, check WAN latency, and identify network traffic across your WAN network. This enables you to allocate resources accordingly to prioritize traffic and react proactively to issues affecting your WAN network.

Top Ten Network Monitoring Tools

While network monitoring tools focus on aspects like performance monitoring, fault monitoring, and account monitoring, they’re also used to examine components such as applications, email servers, and more. While there are several network monitoring tools available in the market, choosing the right device with in-depth research and tracking capability is challenging.

We’ve listed the top ten performers in network performance monitoring tools because we know how taxing choosing the right tool can be.

A range of plug-in extensions called ZenPacks are available, encompassing everything from devices to services. There are open-source plug-ins for Amazon Web Services, Apache HTTP Server, Dell, Docker, HP, and Cisco, to name a few.

Summing Up

Network performance monitoring solutions can help companies prevent a disaster even before it happens. They can deliver visualizations on key performance metrics while automatically generating performance reports, which ideally include both recent and historical data. While it’s useful for tracking the performance of your systems, it also helps organizations deal with security threats invading networks. With an accurate performance monitoring tool, organizations can be alerted to events that might indicate the presence of malware in a system, for example, abnormal data transfers, failing systems, etc.

To truly understand network performance, organizations must observe every aspect of a network because any portion of it businesses skip monitoring could be a cause of performance issues and in turn might affect the entire environment. Network monitoring tools are a must-have to keep networks organized and well-maintained—they provide visibility to manage devices and help ensure they’re available around the clock for the organization and its users.
