What Is Network Monitoring?

Network monitoring is a vital IT process in which all network components—firewalls, servers, routers, and switches, to name a few—are monitored using specialized tools. Businesses of all sizes must take a proactive approach to network monitoring. In doing so, you can identify bottlenecks and performance issues at their initial stages.

The critical process is simplified through network monitoring software. Armed with the right tools, you can oversee and analyze your networks in real-time. You can fully understand the performance metrics through data visualizations and reports. Then, you can respond to issues appropriately as soon as you detect them. Proactive network monitoring enables you to avoid downtimes and unnecessary financial losses.

How to Choose the Best Network Monitoring Tool

Every company has varying requirements for network monitoring solutions. Given that the market has a multitude of tools and solutions to offer, you must carefully select the most suitable option for your company.
Here are a few factors that might help you with your decision.

  • Intuitive and highly automated

A network monitoring tool should allow you to dedicate time to other value-added tasks instead of keeping a permanent eye on your infrastructure.
Look for intuitive, highly automated tools so IT personnel won’t actually have to keep constant watch over their network components 24/7. Choose tools with early-recognition functionalities, customizable notification systems, automatic reports, and other features that can help you save valuable time.

  • Full-scale test version

If you’re looking for a robust solution, you need more than a free network monitoring tool. Paid software comes with a wide range of features and functionalities that help you ensure your system’s health. Since these tools don’t come cheap, you have to make sure the one you pick is a worthwhile investment.

You can start with tools that provide full-scale versions of the software for a limited number of days. It should be enough time to decide if a tool makes a suitable match for your organization. At the same time, it’s the perfect opportunity to test the vendor’s support team.

Ideally, you should choose a service provider that can offer great support whenever you need it. This way, you can guarantee that your IT team has the support it needs if complications arise.

  • Simple, easy to use

Overseeing all your network components doesn’t have to be complicated—that is, if you look for a network monitoring service that’s simple and user-friendly. It’s important to find tools that you can easily customize to fit your company’s unique demands. This gives you easier access to much-needed data or insights.

Some solutions, for instance, provide ready-to-use templates for hardware and software system components. You can customize them if you want to.
