3 good reasons for PRTG as your server monitoring software

An Integrated Solution

An Integrated Solution

Whether just a few servers or a large server farm: PRTG adapts dynamically to the size of your server landscape. And should you acquire more servers, all licenses are individually upgradeable. PRTG is an integrated solution: whether processors, memory, cooling fans, power supplies, or other components, our Server Monitoring Tool simultaneously monitors your servers as well as your entire infrastructure. PRTG immediately recognizes if a router or switch fails and causes a disruption in the server. Even virtual servers are recognized automatically and included in the monitoring.

Prompt Alerts

Prompt Alerts

Servers are the main elements of every IT infrastructure. Without them, a company is more or less unable to function. PRTG ensures system failures are as short-lived as possible – or even prevented in advance! Thanks to the e-mail or SMS alert feature, you’ll know straight away if complications arise. Locate errors directly: this will save you lots of time. You can even define the alert threshold values yourself. This means you’ll be notified before a shortage leads to a crash.

Capacity planning

Capacity planning

PRTG helps out with your capacity planning. Our Server Monitoring Tool lets you to promptly recognize when in the medium to long-term it will be necessary to increase your capacities. Our dashboard presents compelling charts which are perfect for convincing your higher-ups with no technical know-how to expand your resources. The tool also features detailed reports providing a basis for scheduling and continual process optimization.

What is a sensor?

by Kimberley, Senior System Engineer

What, exactly, is a "sensor" within PRTG? What is a "channel"? This video discusses PRTG sensors and channels, including a few concrete examples of both, to illustrate this fundamental PRTG concept.

PRTG monitors all types of servers – even in distributed networks. Here are a few examples of the kinds of servers for which PRTG provides predefined sensors so you can get started with your server monitoring at once:


Mail Server Monitoring

Mail servers, in particular, are sensitive issues for companies. When mail server glitches occur, employees are quick to complain, putting the support department under intense strain. With PRTG, you can monitor your mail servers permanently and be alerted in a timely fashion. IMAP, POP3, SMTP, and many more: we supply more than a dozen sensors for your mail server monitoring.

Web Server Monitoring

Web Server Monitoring

Website performance is a deciding factor for many companies – all the more so when they offer products and services via their websites. Downtime is costly, right from the very first second. That’s why PRTG also makes a whole range of sensors available for your web server monitoring.

Database Server Monitoring

Database Server Monitoring

Practically all company information is stored in databases. When it comes to databases, performance is also the basis for the effective functioning of each and every department. PRTG thus offers a variety of sensors which are available for immediate use. These include sensors for the monitoring of MySQL, Microsoft SQL, and Oracle SQL. You can selectively choose HTTP content or perform database queries.

File Server Monitoring

File Server Monitoring

If firms can’t access information, then nothing works. One of the tasks of administrators is therefore to ensure the file server runs smoothly, and as with other servers, avoid crashes. It’s not uncommon for administrators to search, say, for a specific FTP server monitoring tool. But PRTG has you fully covered in this area as well. For you get around 20 sensors just for your file server monitoring.

More server monitoring sensors

Monitor as many servers as you like...

With PRTG, you get a number of other predefined sensors which provide an overview of your entire server landscape in no time at all. You can create your own sensors whenever you want, and use the API to adapt PRTG to absolutely any special situation.

More server sensors

Virtual Server Monitoring included


In many companies, virtual servers are already a part of the IT structure. And for good reason: memory, hard disk space, and computing power can be allocated to individual applications dynamically. Resources are thus used in a considerably more efficient manner. PRTG monitors your virtual servers, right down to the very last detail.

„Hey Arne, how do I avoid false alarms during server maintenance?“

"In practice, repairs in the short-term will be necessary. While working, your monitoring will not trigger false alarms. The one-time maintenance window allows you to pause monitoring for each individual device or device group. For regular maintenance, with PRTG you can easily create an automated schedule."
