Network Monitoring Definition and Solutions

Network monitoring is far more strategic than its name implies. It involves watching for problems 24/7, but it's also about optimizing data flow and access in a complex and changing environment. Tools and services are as numerous and varied as the environments they guard and analyze.

How important is network monitoring?

You might think that if the network is up and running, there is no reason to mess with it. Why should you care about adding another project for your network managers to scribble across their whiteboards, already crammed floor-to-ceiling? The reasons to insist on network monitoring can be summarized on a high level into maintaining the network's current health, ensuring availability and improving performance. An NMS also can help you build a database of critical information that you can use to plan for future growth.

Network monitoring is like a visit to a cardiologist. You're combining experience, judgment and technology to chart a system's performance.

Your doctor is watching for danger signs as blood flows through vessels, valves and chambers of the heart, while your network monitoring systems are tracking data moving along cables and through servers, switches, connections and routers.

That analogy holds up especially when you consider how important real-time information is in both cases.

Of course, network monitoring differs in that smart companies don't settle for annual snapshots of system performance. Nor do they monitor only after the appearance of disturbing symptoms. They monitor their networks 24 hours a day, every day.
