PRODUCT OVERVIEW

“From a server perspective, we're monitoring all of the key components of our service such as CPU usage, RAM disk space, the Windows services that it's running, and network connectivity of that server. In terms of networks, we’re monitoring all of our switches, firewalls, and access points. It’s really useful to be able to easily pull performance metrics from the PRTG dashboard.”

Ollie Kerslake, Infrastructure Lead
Riverford Organic Farmers

“The tool has given us greater control over all types of devices connected to the network (switches, IP telephony, security cameras, IoT, WiFi) that previously remained opaque when dealing with service incidents. This has improved our ability to diagnose and resolve problems, which has translated into greater efficiency and a better user experience in both internal and public services.”

Jordi Tolosà Bel, New Technologies Technician
Vinaroz City Council

“Our objective was to be able to monitor the health of our most critical servers containing data and applications, but also the flows and bandwidth between headquarters, our 50 servers in the cloud and the 15 servers at our production sites. For us, it is essential to have a proactive approach to understand where the weaknesses of the IT system are to be able to improve them.”

Marc Boullier, CIO

Monitoring free disk space: FAQ

 

What is a free disk space monitoring tool?

A free disk space monitoring tool helps you track and analyze the available and used space on your storage devices, such as hard drives, SSDs, or flash drives. These tools highlight which files, folders, or apps consume the most space and offer insights to optimize storage and prevent system slowdowns.

How does PRTG function as a disk space analyzer?

PRTG provides a comprehensive storage analyzer that scans and reports on disk space usage. It shows detailed metrics like file size, largest files, and disk usage across subfolders. With customizable dashboards and real-time scan results, you can visualize data using formats like pie charts and treemaps to make informed decisions quickly.

Can PRTG monitor disk space on Windows 10 and Windows 11?

Put some clear and concise content in here. Keep your reader in mind. What are they trying to do? What are they hoping to learn? Why are they reading this? Help them out and use the tone and voice of your organizationYes, PRTG supports disk space monitoring on both Windows 10 and Windows 11 operating systems. It can scan and analyze storage drives, track junk files and system files, and even identify problems that traditional Windows Explorer might miss. This makes it easy to keep your Microsoft-based systems running efficiently.

How does PRTG compare to apps like TreeSize or WinDirStat?

PRTG stands out by offering broader network monitoring functionality compared to apps like TreeSize or WinDirStat, which focus solely on local storage. In addition to disk space analysis, PRTG provides network performance monitoring, device tracking, and customizable alerts, making it a more powerful solution for complex IT environments.

What makes PRTG user-friendly for disk space monitoring?

PRTG offers an intuitive user interface with features like tree view navigation and easily customizable dashboards. You can quickly identify storage bottlenecks, such as duplicate or large files, and receive real-time alerts when critical thresholds are reached. This streamlined approach reduces the complexity of monitoring and managing disk space.

Can PRTG help with storage cleanup and optimization?

Yes, PRTG helps you clean up and optimize your storage by giving you a clear view of what is taking up the most space on your drives. It highlights junk files, unnecessary system files, and the largest files, allowing for efficient disk cleanup. By proactively managing storage, you can prevent space-related issues and ensure your system runs smoothly.

What is a sensor in PRTG?

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

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
