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

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

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

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.

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

 i How PRTG defines sensors

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

 “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.“

A sampling: Seven sensors for Windows server monitoring

 iWMI stands for Windows Management Instrumentation. Designed by Microsoft, it is an infrastructure for the standardized management of data and information that is device independent. Since Windows 2000, WMI comes preinstalled with Windows operating systems.

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: This 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: This sensor monitors any product which can be inspected by the Windows Security Center.
  • PerfCounter Custom Sensor: This sensor monitors an individually-compiled set of Windows performance counters.
  • WMI Custom Sensor: This sensor uses WMI to execute an individual WQL query and monitors the subsequent return value.
  • Windows Process Sensor: This sensor monitors a Windows process using performance counters or WMI.
  • REST Custom Sensor: This sensor monitors the availability of RESTful APIs, recognizes the content of XML an JSON files automatically and creates suitable channels for values.











Tip: The PRTG 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.

Windows uptime monitoring: How PRTG can help


The Windows Update problem

In order to execute pending updates in Windows systems, a reboot is almost always required. As a result, the computer or server shuts down during the update and then restarts, creating downtime that can lead to applications being unavailable, and subsequently to work interruptions and even losses in sales. Many administrators solve the “update problem” by distributing services across several servers (Windows clustering) to ensure important systems stay available during downtime, which can, of course, occur during other situations besides updates.

More about update monitoring >>

How PRTG can help: PRTG keeps a constant eye on uptime, and lets you compile comprehensive statistics. Show your colleagues and higher-ups that you have a firm grip on your network! In the event of a malfunction, you’ll immediately receive a notification via our tool so you can keep downtime to an absolute minimum. The alarm system is an integral part of PRTG.


Show Windows uptime

“Show Windows uptime” is a common online search amongst network administrators. There are several options for viewing uptime (runtime). One such possibility works via the command line. Enter the command “Systeminfo” into a Windows command-line tool. Windows will then display, among other information, the “System Boot Time,” or the date and time when the system was last rebooted. Another option is the Task Manager. In the “Performance” tab, the CPU’s “Up Time” is displayed in days, hours, minutes, and seconds.

How PRTG can help: PRTG provides you with a constant overview of uptime. Gone are the days of having to check uptime manually – PRTG displays it on your dashboard automatically. You can also have Windows uptime statistics generated automatically, and if desired, configure your own alarms.


3 PRTG sensors for querying uptime

There are several ways to calculate uptime with PRTG, including with the following sensors:

Ping sensor

The Ping Sensor measures ping time. If a device is non-responsive, then it is clear at once that the device is currently turned off or unavailable in the network. You can check uptime and downtime in the sensor statistics.

SNMP system uptime sensor

The SNMP System Uptime Sensor will show you how long a device has been active. This sensor also works on non-Windows devices!

Windows system uptime sensor

You can also use WMI to keep an eye on your Windows System Uptime.
