Network Performance Monitoring: How to Measure Network Performance

Network Monitoring

It’s Friday evening, and just as you are about to leave work, you receive a flood of tickets concerning slow network issues. Your clients are complaining about everything from crashing websites to unresponsive servers. It’s chaos, and you see your plans to Netflix and chill going out the window. A network monitoring tool could have prevented this scenario.

In today’s connected and digital world, where businesses are operational 24/7, network performance monitoring helps MSPs and IT departments prevent connectivity-related outages and other performance issues. Read on to learn the why and how of network performance monitoring and its impact on business productivity, profitability and reputation.

What is network performance monitoring?

Network performance monitoring involves assessing and optimizing the various networking infrastructure components to improve performance and usage. Businesses cannot succeed without a reliable and efficient network in place. Therefore, IT professionals constantly monitor their company’s and clients’ network infrastructure to ensure it runs efficiently and optimally and data and information move securely and uninterruptedly.

Today, networks must be built and managed to accommodate a variety of devices, applications and data types. Many factors contribute to the complexity of network setups today, including mobile device proliferation, data explosion and cloud computing. Moreover, depending on changing business needs, IT professionals have to reconfigure the networks, optimize them, change settings and even upgrade the infrastructure to make it more efficient.

Network monitoring helps IT professionals manage all these elements from a single tool. It helps them detect issues in real time and take corrective action to avoid downtime and productivity losses. Bandwidth and latency issues are signs of poor network management and, if left unattended, can further degrade performance. Network monitoring also helps and prevents cybersecurity breaches. Regular network monitoring helps IT professionals identify and fix vulnerabilities before threat actors exploit them.

Why is network performance monitoring important?

Network performance monitoring enables IT professionals to identify and troubleshoot issues before they snowball into bigger problems and adversely impact business operations. A glitchy or unreliable network can stall business operations, hurting productivity and frustrating customers and users. Monitoring networks not only helps IT professionals avoid these outcomes but it also optimizes the use of resources. An underutilized network increases costs, while overutilization causes congestion and painfully slow performance. By using advanced network monitoring tools like Traverse, businesses can easily visualize their entire network on a topography map and diagnose and fix issues right from the dashboard.

Network monitoring is also a cybersecurity strategy and plays a big part in keeping threats and breaches at bay. Network monitoring tools can detect anomalies in a network traffic pattern or unauthorized activity and alert IT professionals. It even identifies the device or region where the problem resides so technicians can quickly quarantine and remediate the issue. Network monitoring is essential to prevent malware like ransomware from gaining access to the network, which can compromise the integrity and security of company and client data.

IT professionals use several metrics to gauge the performance of their networks. Some common ones are latency, throughput and bandwidth, which we will look at in more detail later in the blog.

How can network performance be monitored?

IT professionals use a network monitoring tool to monitor their networks, collect data on network performance, analyze it, remediate issues and create informative reports. Here are some methods IT professionals use to monitor their networks.


Monitoring Simple Network Management Protocol (SNMP) devices, such as routers, switches and printers, allows system administrators to quickly detect and remediate potential issues before they can cause major damage to an organization’s productivity.

Standard monitoring of SNMP devices involves configuring of network devices to report various pieces of data. This data gives a detailed view of the health and operational status of these devices. Network monitoring allows devices to generate alerts when events occur outside the set thresholds. This flags networking issues that can lead to IT system and service downtime.

For example, for network devices like routers and switches, SNMP monitoring can collect information such as interface metrics for operational status, bandwidth in and out, and errors in and out. For printers, information such as operational status, printer current status, detected error state and printer cover (i.e., door) status can be collected.

Flow data

Network flow data monitoring is a way to get insights into the health of the network traffic, everything from the source and destination of the traffic to data transferred and the protocols used. It is combined with other network monitoring methods to comprehensively view a company’s network performance. Flow data is configured in devices like routers and switches and collects data from IP traffic. When analyzing data, it doesn’t drill down to the details like packet capture monitoring methods. Still, it gives a general overview of the traffic that helps to identify anomalies in traffic patterns that can indicate a security incident.

Packet capture

Packet capture is another way to analyze and detect anomalies in network traffic. Instead of looking at traffic summary, it intercepts and captures data packets from anywhere on the network or a subnet. Packets are bits of information that travel from the source to the destination. Information transmitted over a network is broken into smaller packets that take different routes to the destination server. At the receiver’s end, they combine to form the complete message.

Two ways to perform packet capture are network tap and port mirroring. A network tap involves placing a device between a switch and the destination server. Port mirroring uses a switch port to send a network packet copy to another switch port connected to a network monitoring connection.

Packet capture allows granular traffic data analysis and provides insights into bandwidth usage and security issues. Network congestion and misconfigured devices can cause dropped packets, resulting in the user not receiving the data properly. A packet capture provides an exact copy of the data for analysis, while flow data summarizes it into a general picture.

What are network performance metrics?

Metrics measure a network’s performance and bring to light the issues and areas for improvement. They help identify potential errors, outages and malfunctions in real time so that IT professionals can resolve them as soon as they arise. Additionally, metrics provide insights into whether network infrastructure and devices are performing optimally. Let’s look at the commonly used network performance metrics:


We’ve all had the experience of restarting our routers to get better internet bandwidth at home. It does help to speed things up. In simple terms, bandwidth is the amount of data transmitted over a network within a specific timeframe. An example is how quickly you can buffer or download a movie. The more data you can download quickly, the faster the network’s speed. IT professionals analyze bandwidth data to optimize usage and stay within the bandwidth threshold. Going beyond the threshold will overburden the network and translate to connectivity issues, slow network and lost hours in productivity.


While bandwidth provides a theoretical insight into the data transmission rate, the throughput metric offers insights into actual data transmitted over different networks. It does this by checking how many data packets reach the destination server. When the throughput metric is low, it means that data packets are being frequently lost or dropped from the network and must be retransmitted.


The lag or delay in data transmission over a network is calculated using the latency metrics. Data is transmitted faster over a network with low latency and more slowly over a network with high latency. Low latency networks are vital in today’s digital world where applications and services are provided online and data is stored and accessed in the cloud. Too much latency in a network can stop applications from working properly and hurt customer satisfaction and business operations.


A jitter is a variation in the delivery time of packets over a network. Data shared over a network is sent to its destination in smaller packets. Depending on how these packets travel, they may experience different network issues, such as congestion or equipment failures, that can impact their arrival times. By reducing jitters, network administrators make data delivery smoother and less glitchy.

Packet loss

While being transmitted over a network, data packets can get dropped, lost or corrupted. When they get corrupted, it disrupts the end-user experience and can be detrimental to business in the case of a client-facing service. IT professionals analyze this metric to reduce packet losses caused by congestion on the network, faulty hardware or software.

Network availability

Business operations are adversely affected by an unreliable network that suffers frequent outages. The result can be a significant reduction in productivity and revenue. Network availability is the simplest and most critical network performance metric that provides insights into how often a network is operational and available for use.

What is a network performance monitoring tool?

A network performance monitoring tool is an advanced software that lets IT professionals view the various components of their network infrastructure on an interactive dashboard. These tools are quick to deploy and provide a network topology map that gives a comprehensive view and insights into the health and status of the network. A network monitoring tool has a host of features that IT professionals can leverage to monitor devices, identify and troubleshoot issues, and take steps to optimize network performance — all in real time. It helps users to work more productively and deliver seamless service to clients, in turn boosting revenue. By uprooting inefficiencies in the IT infrastructure, the tool helps reduce the costs associated with downtime, maintenance and upgrades, thus increasing the bottom line.

A great network performance monitoring tool should integrate with other core IT tools like ticketing, IT documentation and BI solutions so technicians can manage tickets from within the same dashboard. This will help technicians utilize the solutions stack fully and provide better network management services. An advanced network monitoring solution should also have automation capabilities on the menu so that technicians can spend less time on mundane tasks and devote more time to other essential business tasks. Lastly, it should provide top-notch reporting so that IT professionals can demonstrate the tool’s value to clients and stakeholders.
