If you ask people outside the SysAdmin microcosm what “network monitoring” means, chances are high, you’ll get only shrugged shoulders as response. Many people don’t know the importance of monitoring. In this post, I will show you 5 great benefits of network monitoring and why you absolutely need a network monitoring tool.

1. You Know What’s Going on in You Network

The bigger the company, the bigger and more complex the network infrastructure usually is. Maintaining an overview of all servers, virtual environments and devices can become a Herculean task for admins. The use of a network monitoring tool will help you stay informed not only about the devices and services running in your network, but also about important performance metrics.

2. You Can Optimize Your Network Performance and Availability

Most of us are aware that productive employees are a key factor for a profitable business. Another key success factor is a high-performance IT infrastructure. A slow internet connection in your office or outages of your servers or your website all cost your business hard cash. Even a slow website can lead to a considerable decline in sales. For example, Amazon found every 100 ms in latency cost them 1 % of profit.
By monitoring your network, you can identify slowdowns and problem areas. With the insights from continuous monitoring, you can schedule resource-hungry tasks like backups or system updates wisely. Also, alerts on network availability issues help accelerate time to resolution.

3. You Are Proactive Instead of Reactive

Getting mails from colleagues complaining about slow-responding servers or realizing that your website is down again puts you into a reactive state. If you want to stop troubleshooting like a firefighter, the use of a network monitoring tool is a must. By identifying potential issues and flashpoints at an early stage, your job role becomes a proactive one and you can correct a lot of issues before they affect users.

4. You Save Time

Network monitoring software pinpoints the root cause of your downtime or performance problems. Whether you face a configuration error or a high traffic fluctuation, a good monitoring tool helps you to get to the bottom of the issue. You don’t have to find the needle in the haystack, and can fix the problem once and for all.

5. You Get Detailed Statistics and Valuable Insights

With network monitoring, you not only get a good overview of your network, but also gain important insights of how the sub-areas of your infrastructure develop. Most monitoring tools offer graphical dashboards and detailed statistics. What is the average CPU usage of your virtual servers? Did your website achieve the “five nines” in terms of availability? Did your ISP fulfill the promised SLAs? The statistics show it in black and white.
