Network management has become increasingly complicated. This is because companies now have a lot of hybrid setups, which means they have on-premise servers mixing with cloud-based resources. International companies even have networks that span the globe! Therefore, you should have an effective network performance monitoring system in place. How well your network performs indicates how well your company will succeed. Specifically, you can suffer severe consequences if your network goes down for even a second.
In this article, I’ll cover network performance monitoring, its importance, how it works, and some best practices to help you out. I’ll end things with a list of the 3 best network performance monitoring tools on the market.
I’ll start with a definition of network performance monitoring.
What Is Network Performance Monitoring?
Network performance monitoring is the process of visualizing data and traffic across your network. You can then use this valuable information to optimize, monitor, and troubleshoot your network if you encounter any issues. Network performance monitoring also allows you to have your network status available at any time.
So now you know the “what”, but why is the process of network performance monitoring important exactly? Let’s find out.
Why Is Network Performance Monitoring Important?
Network performance monitoring is important because it can help your network admins find and resolve problems more quickly. It can also help you find these issues before they affect your users. Additionally, network performance monitoring can provide you with data and metrics your team can use to optimize your network further.
Having said that, I’m sure you’re curious about how it works. No worries, I’ll talk about that next.
How Does Network Performance Monitoring Work?
You can use several diverse telemetry tools for network performance monitoring. You can look at device metrics, also known as flow data, such as CLI, API, logs, etc. Additionally, you can monitor network traffic such as NetFlow, jFlow, etc. Finally, you can even monitor the data packets themselves! Let’s go over these in more detail.
Your networking devices, such as routers and switches, create flow data. This data lets you know which devices are communicating with other devices. Flow data also provides information on how long and often these devices communicated. This valuable info gives you a holistic view of what’s happening inside your network. It’s important to mention that you’ll get all the metrics required from the flow data, but you won’t know what data got transferred.
Simple Network Management Protocol (SNMP)
You can use Simple Network Management Protocol (SNMP) to manage and monitor devices connected to your network. This is a widespread protocol that many businesses commonly use. It can quickly detect network outages, device failures, etc. In essence, SNMP is a great diagnostics tool that inspects bandwidth utilization, packet loss, errors, latency, memory, and CPUs.
Packet capture involves copying data packets and keeping them for analysis. Specifically, this analysis helps system admins find and solve networking issues. Some examples of these issues include security threats, troubleshooting errors, packet loss, and packet resends.
Now that you know how networking performance monitoring works, I’ll look at some best practices.
Network Performance Monitoring Best Practices
You should work with your system admins and your IT team to implement best practices to support your overall network performance monitoring goals. Here are some of those best practices.
Make an Inventory
This will be an easy task if you’re just starting. Otherwise, you’ll have a lot of work to do in taking inventory of all of your devices. However, some network monitoring tools (more on those later) have mapping tools that enable you to easily take inventory of all your devices.
Set a Baseline
You won’t be able to spot any anomalies if you don’t have a baseline of what your network looks like when it’s running optimally. Not having a baseline can also make detecting issues in your network challenging. This is why you should initially collect a lot of data and set a clear baseline to refer to.
Create an Escalation Procedure Plan
You’ll want to know what skills your team has to handle different problems in your network. Additionally, you should consider creating an escalation matrix that contains all the networking employees, their specialties, and the order of escalation. Having this information in one centralized location helps to reduce confusion when severe issues pop up.
Maintain Availability and Have Failover Plans as Backup
The worst thing that can happen to your network is if it goes down or starts underperforming. You’ll want to ensure you’re keeping your network’s availability high. Also, have a failover plan as a backup in case your network goes down. You can use this plan to easily get your network up and running if your network goes down. This is especially important at peak business hours.
Plan for Growth
You should always have a plan to scale up—and sometimes down. Your business’s needs are constantly changing, and your networking team needs to be ready to move at a moment’s notice. In short, a growth plan ensures you can increase service quality and reduce interruptions.
Those are some important best practices to take note of. Next, I’ll take a look at some of the best network performance monitoring tools out there.

How do network performance monitoring tools work?
The simplest command works by pinging a host to test availability in an IP network. A ping can return data such as host activity and packet loss. Pinging is very basic, however. With a network monitoring suite, you can have many high-end tools at your disposal.
What is network performance management?
Network performance management refers to all the techniques used to manage performance across a network. The process requires constant monitoring of mission-critical network functions and metrics.
What is a throughput monitor?
Throughput is how much data a network can transmit within a set period. For example, an ethernet connection that transfers data at a rate of 50 Mbps has a throughput of 50 Mbps. Network throughput monitoring can help protect the high-speed transmission rates.
What types of network monitoring are available?
You have four types of network monitoring available: availability monitoring, configuration monitoring, performance monitoring, and cloud infrastructure monitoring. These types are generally all lumped into the general category of network monitoring.
What features are a must in network monitoring solutions?
When selecting a network monitoring solution, you’ll want to ensure they have the following features: real-time data dashboards, auto device discovery, root cause analysis, network maps, scalability, customizable dashboards, and alerts. You’re good to go if you find all of these features on a particular tool!
