What is Network Monitoring?

Network monitoring refers to the monitoring of an entire network environment. Its goal is to allow sysadmins to work in a better, quicker, and more efficient manner. Network monitoring focuses on parameters such as bandwidth consumption and the availability of network devices. Some of the monitored devices include the local and Internet-based systems in an IT environment, such as databases, applications, clouds, servers, and network infrastructures. Network monitoring allows admins to ensure their networks run smoothly, effectively, and free of errors.

What should I monitor?

The mere implementation of a network monitor is not enough. The key to effective network monitoring in real time is to ensure that the chosen tool has been configured to monitor what are essentially a network's vital signs: availability, speed and usage.

Monitoring network availability allows both internal and external parties to access the services, including websites and you can determine whether the mail servers and leased lines are working.

Monitoring network speed with bandwidth monitoring prevents your websites and network services from losing visitors or frustrate users due to slow-loading pages, files or images.

Finally, usage monitoring enables you to accurately assess CPU load and learn just what sort of work the servers are doing at times of different the day.

General network status

With PRTG, a quick glance is all it takes to check the status of your entire network. PRTG gives you peace of mind and lets you confidently go about your other tasks. If a malfunction occurs or the status of a device changes, you'll be notified immediately and can take action at once.

Network devices

All large networks contain countless different devices made by a variety of manufacturers. These include switches, servers, workstations, and routers. Many monitoring tools can only monitor the devices of specific manufacturers while others require expensive add-ons, e.g. to monitor Cisco devices. The advantage of PRTG is that it comes with sensors for monitoring the devices of nearly every manufacturer.

Monitor network traffic

PRTG is the perfect tool for monitoring network traffic. It shows you which applications, connections, and data types are putting the greatest strain on your network. In the event of disruptions or overloads, the PRTG alarm is triggered at once. 

 

The rundown on network monitoring tools

Why do you need network monitoring?

Once a network reaches a certain size, it makes sense to monitor it permanently. Downtime and malfunctions can cause the performance of the entire company to suffer. At the same time, IT managers are under more and more pressure. They’re forced to act quickly but often don’t know where the problem lies. PRTG helps IT managers get a handle on their network.

What exactly is meant by “a certain size?”

PRTG is used by companies with a few dozen workers as well as by companies with several thousand employees. Its licenses are customized in accordance with the required number of sensors. Our software also provides peace of mind to the sysadmins of smaller networks. 

Can you monitor individual devices such as a router or a switch?

You get to choose which devices are monitored by the PRTG network monitoring tool. You also get to define the scope of your monitoring. For example, you can choose to only monitor the CPU, free disk space, or certain ports.

How does monitoring work?

Our software comes with sensors that you create for each of the devices you wish to monitor. These sensors send monitoring data to the core PRTG server. Check out the following video to learn more about sensors.
