Windows Monitoring Software:
5 advantages of PRTG






i NetFlow is a protocol for collecting, aggregating and recording traffic flow data in a network. NetFlow data provide a more granular view of how bandwidth and network traffic are being used than other monitoring solutions, such as SNMP. NetFlow was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches and has been supported on almost all Cisco devices since the 11.1 train of Cisco IOS Software.

Overall monitoring solution

PRTG provides an overview of your entire network. Our software monitors database, mail, web, and virtual servers. Whether CPU, memory, disk space, traffic, uptime, and more: PRTG is an all-around solution that provides peace of mind. The alarm and reports features are also included.


PRTG uses a variety of technologies for its Windows server monitoring. Among these technologies are Windows Management Instrumentation (WMI) and Windows performance counters. As an alternative, you can also use SNMP, which generates significantly lower loads. We also offer packet sniffing and NetFlow sensors for the detailed monitoring of individual data packets.

Individually customizable

Countless parameters can be monitored in Windows. When specific problems arise, administrators need individually customizable monitoring software. PRTG comes with several custom sensors which you can configure to meet your own particular needs. And that means you will quickly get to the root of problems.

Windows Event Log Monitoring

PRTG analyzes Windows Event Log files by default – and without much fuss. Event Log files include application and system logs, among others. If an error occurs in the Windows operating system, a special PRTG sensor immediately sounds the alarm so you can fix it.

Windows Security Monitoring

Security-related data (such as the status of antivirus software) is displayed in the Windows Security Center. PRTG retrieves this data and integrates it into your monitoring overview. You therefore get a constant overview via your dashboard. And thanks to the PRTG app, you can even keep an eye on things while on the go.

Your Windows Monitoring at a glance
– even on the go

PRTG can be installed within minutes and it's compatible with many mobile devices.


Using a different tool? Why you should switch to PRTG:

 “Hey Greg, what would you tell administrators looking to monitor their Windows Server with PRTG?“

„PerfCounter custom sensors are some of the most useful sensors to be overlooked by users. Imagine SNMP sensors, but for Windows performance counters. Simply find out the name of the counter you wish you monitor. There’s a great knowledge base article on this topic.
Once you have the name, setting up the sensor is a piece of cake. It’s amazing to think of how many PerfCounters are really available for Windows applications, especially those which don’t come from Microsoft itself. These counters often offer insights into applications or processes which you may have once thought to be impossible.“

Greg Campion is a SysAdmin at PAESSLER AG.

A sampling: Six sensors for Windows Server monitoring



PRTG comes with predefined sensors for monitoring conventional parameters such as CPU, memory, and the network card. We also offer a number of useful sensors which you can customize yourself.

  • WMI Event Log Sensor: The WMI Event Log Sensor reads the Windows Event Log and provides easy-to-read visuals of the data.
  • Event Log Windows API Sensor: This sensor uses the Windows Application Programming Interface (API).
  • WMI Security Center Sensor: The WMI Security Center Sensor monitors any product which can be inspected by the Windows Security Center.
  • PerfCounter Custom Sensor: The PerfCounter Custom Sensor monitors an individually-compiled set of Windows performance counters.
  • WMI Custom Sensor: The WMI Custom Sensor uses WMI to execute an individual WQL query and monitors the subsequent return value.
  • Windows Process Sensor: The Windows Process Sensor monitors a Windows process using performance counters or WMI.

Tip: PRTG’s System Information Feature for Windows



A System Information Feature is available for every Windows device set up in PRTG. An additional tab displays information on your Windows system, such as its IP address, which hardware is installed, and the software that is running. Current processes are also listed there.

Paessler Study on WMI Network Monitoring


























Paessler AG recommends SNMP for the everyday monitoring of Windows servers, for this technology generates extremely low loads. Two other possibilities are performance counters and WMI. Administrators should not create more than 200 WMI sensors per probe, for otherwise performance will take a major hit. 

WMI is the Windows standard for network monitoring. Paessler AG periodically performs tests to be able to offer advice on using WMI. PRTG monitoring should work effectively and without disruptions. One of our larger studies was carried out in 2012. Here are the most important results:

  • For PRTG core server installations, the 2012 Windows Server 2008 R2 is best suited for quick WMI monitoring. The more current Windows Server 2012 R2 has proven to be just as effective and is also our overall pick for PRTG installations.
  • According to the 2012 study, you should opt for Windows Server 2008 R2 for client systems (whenever possible). Newer versions such as Windows Server 2012 R2, Windows 8.1, Windows 10, and Windows Server 2016 also perform well with WMI.
  • By contrast, Windows XP, Server 2008, Windows 8, and Server 2012 are less suitable for client monitoring.

Windows monitoring: Other features

Multi Router Traffic Grapher: Many are in search of a multi router traffic grapher, or MRTG. An MRTG is an older, technically-limited monitoring tool which is often extremely difficult to install on Linux systems. PRTG was previously called “MRTG for Windows.”

Windows Ressource Monitor: Windows also offers tools for monitoring. These include the Windows Resource Monitor. With this tool, you can only ever see one value at a time, such as traffic, CPU load, or memory usage. This makes comprehensive monitoring more tedious than it needs to be.

PRTG: The swiss army knife for sys admins

Adapt PRTG individually and dynamically to your needs relying on a strong API:

  • HTTP API: Access monitoring data and manipulate monitoring objects using HTTP requests
  • Custom Sensors: Create your own sensors for customized monitoring
