Pretty much every company IT infrastructure is built with NAS and virtual storage systems. It therefore makes perfect sense that NAS devices be included in network monitoring. The good news: QNAP monitoring is set up in 3 quick and easy steps. On this page, we’ll show you how to effectively monitor your QNAP NAS systems.


QNAP and NAS: What do they mean?

QNAP stands for “Quality Network Appliance Provider.” QNAP is actually a company from Taiwan. QNAP Systems, Inc. offers network solutions for file sharing and virtualization, but is also a well-known manufacturer of NAS devices. QNAP monitoring refers to the monitoring of these network solutions.

An NAS (Network Attached Storage) is a storage device that is directly connected to a corporate network. NAS systems have a processor, an operating system, and one or more hard drives. They communicate via the TCP/IP protocol. NAS devices are like small computers or file servers – which can be monitored around the clock by way of QNAP monitoring.

What makes NAS systems so popular? 

  • They provide for additional storage space in corporate networks.
  • This storage space is entirely customizable.
  • Data, files, and folders can be saved and managed from one central location.
  • They allow for file sharing.
  • Intuitive access as NAS systems are displayed as local file systems on the computers or mobile devices of employees

What makes QNAP NAS systems unique?

Why QNAP? Manufacturers such as QNAP provide NAS devices that are already configured and installed with an operating system. This makes setup extremely easy.

QNAP offers a variety of NAS solutions for a number of different industries. Among other things, these solutions help optimize network availability. QNAP NAS systems are suitable for the IT infrastructures of small to medium-sized businesses. QNAP not only provides for additional storage space, but also services and features to improve the productivity of companies with all kinds of different functions and budgets.


What is QNAP monitoring?

QNAP monitoring is nothing more than the monitoring of NAS systems from the manufacturer QNAP. Among other things, it lets you monitor:


  • icon check white 2
    The status of hardware

  • icon check white 2
    The status of the system

  • icon check white 2
    The status of logical and physical hard drives

  • icon check white 2
    Input/output operations

  • icon check white 2
    Network connections

QNAP monitoring software lets you keep a constant eye on all these values and parameters. As a result, you'll ensure data is safely stored and easily accessible at all times.


Why is QNAP monitoring important?

For one thing, an NAS system often contains multiple physical hard drives. And many of these physical hard drives are combined with logical hard drives. NAS systems must therefore be monitored around the clock to provide IT administrators with the information they need on the status of their drives

By monitoring your NAS, you’ll be able to keep an eye on the remaining amount of storage space, and thereby take appropriate measures to ensure you have enough space for the future.

More benefits of QNAP monitoring:



QNAP monitoring lets you make sure data has been backed up correctly. Regular backups are the basis for safe and secure data.



QNAP monitoring helps you detect bottlenecks that can slow down access to data.

A sneak peek at QNAP monitoring in PRTG


Does PRTG come with special sensors for QNAP monitoring? 

 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.

IT administrators can use three PRTG sensors to optimize the monitoring of their QNAP NAS systems:


Tutorial: Setting up and configuring QNAP monitoring

Step 1: Enable SNMP on the NAS device


The Simple Network Management Protocol (SNMP) is used for the monitoring. The SNMP service must therefore be enabled on the NAS device. On a QNAP device, the “Enable SNMP Service” option is located on the control panel homepage.

Step 2: Enable SNMP in Windows


If you use Windows, then you may need to enable SNMP in the settings of your system (under “Windows Features”).


Step 3: Install QNAP monitoring software and start monitoring

Download the Paessler PRTG QNAP monitoring tool and double-click on the EXE file.

The built-in Auto Discovery feature will launch, automatically detecting and listing the SNMP-compatible network devices that are connected to the network. Once you’ve completed these initial steps in PRTG, you can immediately get started with your monitoring.
