When It Makes Sense to Invest into Network Monitoring Software

Any business with network components should be investing in monitoring software. These tools will ultimately become the first line of defense when network performance declines or applications go down. 

There are lots of different network monitoring tools with functionalities for varying use cases.

Overall, the solution will provide you with the full health and visibility of your network and any devices on that network. 

In many cases, network monitoring tools are designed for larger businesses, SMBs, and enterprises. But even small businesses can benefit from IT network monitoring. All managed service providers (MSPs) definitely need network monitoring software. 

It’s too early to invest in network monitoring if you don’t have any critical devices on your network. If you can afford some outages, downtime, or poor network performance, then you don’t necessarily need the software. You can always wait for a problem to occur, and repair it after the fact.

Methodology For Choosing The Best Network Monitoring Software

Choosing the right network monitoring software for your business can be challenging—there are so many factors that must be taken into consideration as you’re shopping around. Fortunately for you, we’ve simplified this process by identifying what you need to keep an eye on as you’re evaluating potential solutions. 

Follow the methodology that I’ve outlined below, and weigh these elements according to your personal needs.  


It’s rare to find two organizations with identical network monitoring needs. Even across similar business sizes and industries, each organization will have slightly different problems or challenges that must be addressed.

Look for a network monitoring tool that allows you to customize your dashboard, policy rules, and everything else required to run a robust network and IT infrastructure. 


How will you know if a network component is running slowly? When will you find out if an application is down?

Make sure the software has alerting functionality. Without it, you’ll have to identify problems on your own (which is nearly impossible to do at scale). The best network monitoring software will alert you before an issue occurs so you can prevent problems from happening ahead of time. 


Identifying a problem with your network or endpoint within your network is only half of the battle. You need to be able to fix that problem as well.

Try to find a solution with built-in troubleshooting functionality. Managed service providers and IT managers typically like to have a remote monitoring solution, as these will come with remote access tools for troubleshooting. 

Network Components

Network monitoring is a broad term. It encompasses a wide range of potential devices or components that need to be managed. 

There are certain software solutions that are designed for server monitoring, while others are better for virtual machines and applications. So it’s important to have a firm grasp on what you need to monitor and manage as you’re shopping around.

Businesses that need to monitor servers in a hybrid enterprise environment won’t necessarily be using the same software as an SMB that needs to monitor workstations and printers. 



Best for Most

Cloud monitoring tool starting at $5 per month so you only pay for what you use. Analyze the health of your entire network, troubleshoot issues, and stop problems before they happen all from a single platform. Includes 400+ integrations out of the box and everything you need to protect your network.


What’s the best network monitoring software on the market today? We recommend Datadog. It’s flexible enough to accommodate the needs of most businesses. 

However, it isn’t for everyone. Make sure you follow the methodology described above as you’re shopping around. Consider the recommended use cases highlighted for each review in this guide as well. 

This will help you find the best network monitoring solution for your business.
