PRODUCT OVERVIEW

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.

Icon search

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.

Icon gauge

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.

Icon warning sign

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.

Icon harddrive

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 tracking 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. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot disk space issues and prevent network downtime.

4 reasons to choose PRTG as your disk space monitoring tool

Icon adapt

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.

Icon alarm

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.

Icon lock

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.

Icon notifications

Stay up-to-date

There’s no need to verify free disk space yourself. PRTG monitors this for you and directly lets you know when free space runs low.

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

Disk Space Monitoring: FAQ

 

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.

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.

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.

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.

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
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.
