Along with use cases and detailed instructions, there are certain best practices to consider when it comes to network monitoring.
These best practices are the foundation for efficient and comprehensive monitoring.


Continuous network monitoring is a must

It can happen so fast: A router goes down, and within no time the entire network begins to suffer. When you’re taken off guard, it can take minutes or even hours to uncover the source of the error.

You should therefore keep a constant eye on your network – regardless of its size – with a tried and tested tool like PRTG Network Monitor. In the worst case scenario, a malfunctioning device or IT service can bring your entire company to a standstill. It goes without saying that this can have a considerable impact on the sales of your company. Not to mention damage its reputation.


Smooth-running devices are vital

For a network to function properly, its routers and switches must always be operational. A single defective switch port or broken Ethernet cable can lead to all kinds of malfunctions and disruptions.

But that’s not all. If a server crashes or the connection of an employee working remotely via a VPN goes down, it’s not long before the entire company feels the fallout. These are scenarios that companies must avoid at all costs. Continuous monitoring of the network infrastructure is therefore a must.

data traffic

Provide for reliable data traffic monitoring

Too much data traffic can slow down your network. For example, excessive throughput strains routers and switches and enormous amounts of data obstruct hard disks and other storage devices. Situations like these cannot always be avoided and therefore have an even greater impact on the performance of the network. IT managers need a tool that keeps them updated at all times, one that lets them quickly take action in the event that data traffic spikes or a storage unit reaches its capacity.

IT security

Monitor IT security with appropriate software

Along with performance, reliability plays a major role in the functionality of a network. Firewalls must be configured properly, antivirus software must be up and running at all times, and updates must be automated. Here, too, it is easy to trip up, such as when the ports of firewall devices are open when they should be closed or automatic updates have accidentally been disabled.

Monitor applications

Monitor applications and their servers

Servers are the backbone of any company. IT managers must ensure that mail, web, database, virtual, and other servers are always up and running. PRTG Network Monitor keeps a constant eye on servers to provide for the necessary assurance. It comes with sensors for IMAP, Apache, and SQL servers, just to name a few.

Discover all the PRTG sensors that allow you to individually monitor each of the devices, applications, and services in your network.
