Have a complete view of your organization’s storage

Storage reliability is essential

Data storage reliability is at an all-time high now since most of your organization information is stored electronically. Storage monitoring is not only disk monitoring, but the hardware that disks plug into, the data stores for your virtual infrastructure and as well as the health of your physical and logical volumes and drives. Detecting the storage performance bottlenecks early can save you time, money and frustration.


Get notified of storage performance issues

With PRTG Network Monitor you can get notifications when you hit specific thresholds on storage performance, alerts when a drive or disk has an error or have a dashboard that shows you all of these performance counters in one view. 


With PRTG, everyone will work with peace of mind.

A sneak peek into PRTG Storage Monitoring

5 ways to keep an eye on all of the storage devices
in your infrastructure

Physical Disk, Logical Disks, Clustered Disk, Volume I/O, Virtual Platform Storage



PRTG alerts you on drive failures, warning on low disk space and utilization



Also includes sensors to monitor files, file content, folders and shares


Support both WMI, SNMP and SOAP Protocols for monitoring disks


Support for Linux disk monitoring with both SNMP and SSH


Multi-vendor storage monitoring


iWhat is a sensor?

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.

NAS devices

Auto-discovery templates of NAS devices for LenovoEMC, QNAP, Synology, Buffalo and NetApp

A few examples

Dell Powervault MDI disk performance metrics, NetApp enclosure hardware level support as well as NetApp cDOT sensors to monitor performance and reliability for physical and logical clusters, Blade operability monitoring for both Cisco UCS and HP as well as many others!


These two WMI sensors notify you
before faulty hard disks can lead to data loss

WMI Disk Health

The WMI Disk Health sensor monitors virtual and physical disks of all kinds like SSD, SATA, or SAS, for example. It shows the health status of a disk, as well as detailed information about the operational status, for example, degraded or predictive failure.

WMI Storage Pool 

The other sensor is the WMI Storage Pool sensor that is especially interesting for large scale projects. A storage pool consists of multiple disks and provides RAID functionality without real RAID hardware. It is useful for the HCI (hyper-converged Infrastructure) solution from Microsoft, for example. The sensor shows operation and health status of the storage pool, as well as free space, and provides detailed information about the operational status like stressed or relocating.
