How to monitor network traffic

Managing the network and detecting security threats in an era of digital transformation have been challenging for network admins, as new technologies introduce new access dynamics. To address these performance-related challenges, IT admins need to monitor traffic, as issues can arise from any endpoint.

However, most complications lie in choosing how to monitor network traffic, because the IT team has to choose a solution that offers multi-vendor support and provides detailed visualization of their network infrastructure's traffic. But if teams are using multiple tools, the process won't be streamlined and it will leave major gaps.

4 steps to building an effective network traffic monitoring approach

As digital transformation isn't slowing down anytime soon, your traffic monitoring should comprise a solid monitoring strategy that helps in smooth transition. Here's a checklist to test how strong your traffic monitoring strategy is.

  • Visibility and control

Though you get deep visibility into your network infrastructure, including devices, applications, and their traffic, not every bit of data is critical to track. Effective monitoring requires careful consideration over what data should be tracked regularly.

For example, it's important to track metrics of primary importance, like tracking mission-critical websites, server logs, and file transfers to make sure they have consistent availability. You need to strike the right balance between gaining visibility and choosing which critical metrics need to be monitored.

  • Optimizing data

Not every organization can simply buy more bandwidth to address every network issue. Most performance issues can start when the bandwidth that is specifically limited for business-critical applications is used by other unimportant apps. In these cases, prioritizing the apps that should get the most bandwidth is necessary. You must implement strategies to build policies, so that the traffic coming to your network is filtered only when it meets your rules.

  • Proactive risk management

Bandwidth is an important resource that requires close attention and preplanned strategies for recovering it when things go wrong. For example, your interfaces might be utilizing all of your bandwidth, but you may not even know about it until performance issues grow so bad that applications won't even open.

A recovery plan is important in these cases, since you can choose the first course of action when your network's baseline behavior is crossed.

  • Do you have a comprehensive network traffic monitor software?

Lastly, the tool you use is what determines your strategies. Without the right tool, your strategies and monitoring may only result in negative outcomes and facing challenges like vendor support and overlaps in data.

Organizations implement a lot of tools to monitor their dynamic network infrastructure under the misconception that they could get broader visibility and tackle downtime. But having a centralized tool that fits all the requirements can help users monitor their networks while gaining maximum visibility, requiring minimal effort and time.

For this, you need to consider a Windows or Linux network traffic monitoring tool that comes with integrations and add-ons. The network traffic monitor you have should also be easy to implement and offer flexibility to customize it.
