PRTG disk space monitoring: What you’ll find on this page
PRTG makes disk space monitoring easy
Custom alerts make it easy to monitor, identify, and prevent storage space issues.
Monitor your network’s disk space and memory in real time
Paessler PRTG is your IT assistant, attentively running in the background, regulating available hard disk space, and providing prompt alerts when there’s an impending deficiency in space or memory.
Take control with informed resource & capacity planning
Planning for future capacity needs can be challenging. Monitoring disk space with PRTG gives you a single, easy-to-understand overview to help you stop unexpected resource shortages, locate “zombie” processes, and reduce overprovisioning instances.
Monitoring can also show you which applications and processes use the most disk space, so you can make more informed resource allocation decisions.
Optimize your network’s performance
Every network contains processes that write data onto the hard disk. Running out of disk space or memory can lead to slow network performance, crashed applications, and bottlenecks in the system.
PRTG performance monitoring ensures server disk space is available for automatic updates, saving user data, and putting data into CRM and ERP software formats.
Detect potential issues proactively
PRTG memory and disk monitoring provide early warning signs of potential issues like low disk space or memory leaks, giving you the extra edge you need to keep your file servers and network running smoothly.
Set your desired alerting threshold value and get back to other tasks. Administrators are alerted when the free space metric falls below this threshold and can proactively free up disk space.
Anticipate hardware & software needs
Hardware monitoring helps you identify hard drives or memory modules that are failing before they cause network outages or data loss.
Not only does disk space monitoring allow administrators to perform timely hardware maintenance, but it also helps ensure application stability by reducing memory leaks and high memory usage.
What disk space monitoring looks like in PRTG
Diagnose network issues by continuously monitoring your disk space on servers, storage and file systems, and other network devices. Show disk space usage, CPU load, and other key metrics in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot disk space issues and prevent network downtime.

4 reasons to choose PRTG as your disk space monitoring tool
Easy to configure
Existing hard drives, their status, and the available disk space are automatically recognized during setup so that you have nothing more to do.
Get real-time alerts
PRTG’s alert system works in real time, notifying you via SMS, email, or in-app push notification when the free disk space value falls below a predefined threshold. Hours of work are saved. Work processes are uninterrupted.
Keep your data secure
Data is becoming more and more valuable, and the loss of precious information (for example, customer data) can be extremely costly. With PRTG, data losses due to failed save attempts are avoided.
Stay up-to-date on free disk space
There’s no need to verify available disk space yourself. PRTG monitors this for you and directly lets you know when free space runs low.

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.
- Monitor disk space on Unix, Linux, and Windows with the SSH Disk Free sensor, the SNMP Linux Disk Free sensor, or the SNMP Disk Free v2 sensor
- Boost network efficiency with performance and disk space monitoring of storage area networks (SANs)
- Stay informed and secure with file modification alerts - you’re alerted if the files you have flagged are modified
- Ensure resource availability by monitoring the existence of files - is a certain file even available?
- Keep an eye on other disk monitoring metrics:
- Hard disk health: automatically diagnose your hard disks with respect to integrity, temperature, and other attributes
- Hard disk speed: Is the speed up to par?
- Hard disk failure: Is the hard disk responsive? Does it display an error message?
- Efficiently manage network resources by measuring the used disk space and available disk space of SMB file network systems with the Share Disk Free sensor

Disk space monitoring: FAQ
1. What is disk space monitoring?
Disk space monitoring tracks and analyzes the storage space in a networked environment to understand the use and availability of drive space. This is essential for maintaining the health, performance, and reliability of a network’s infrastructure.
2. How does disk space affect server performance?
When a server’s disk space is low, you’ll quickly start to notice a degradation in performance, as well as a failure of automated tasks. Without the available space to handle backups, updates, and data saves, servers cannot work properly.
3. How does PRTG monitor the disk space of your servers?
PRTG monitors disk space on Windows servers, Linux servers and web servers using dedicated sensors that track available storage. It employs WMI or SNMP protocols to check Windows servers, ensuring that you're alerted before disks run low on space. For web servers, PRTG monitors file storage, including web content and log files, regardless of the operating system.
The system allows setting thresholds that trigger notifications via email, SMS, or push notification if disk space is running low, enabling prompt action to manage storage and maintain server efficiency. This proactive monitoring ensures servers are not compromised due to insufficient disk space.
4. What systems does PRTG run on?
PRTG is a hard disk space checker for Windows, Linux and Unix systems and can monitor disk space on physical and virtual drives.
5. What are my options if PRTG tells me my disk space is getting full?
It’s essential to take immediate action to prevent data loss and system crashes. There are several viable options, including:
- deleting unnecessary files
- archiving or moving data
- resizing partitions
- upgrading hardware
- compressing data
6. 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.
