SAN monitoring: PRTG offers extensive monitoring for your storage area networks


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.

Data is the lifeline of any modern corporation. Maximum availability, speedy throughput and security questions are therefore the issues which matter the most. Storage area networks allow for the continuous, high-speed transmission of large amounts of data. These networks use RAID technology to ensure high data redundancy and security. PRTG SAN monitoring lets you quickly identify hardware errors, drops in performance, and problems with capacity.


PRTG comes equipped with all the necessary sensors and features for monitoring and securing your storage area networks. PRTG speeds up the troubleshooting process and allows you to proactively bypass errors by promptly redistributing resources. Your co-workers will be spared unnecessary hassles and delays while accessing data, and the company’s processes will reach peak performance.

PRTG helps you ensure your data is always accessible.

A sneak peek at PRTG SAN monitoring


How SAN monitoring with PRTG works

PRTG comes with four sensors for SAN monitoring that you can use with the products of a wide variety of manufacturers. Some of these include Dell PowerVault, Dell EqualLogic and NetApp. PRTG also offers several SAN sensors which are manufacturer-specific, and will even let you customize your own sensors, by using, for example, SNMP or a script.

The four manufacturer-independent SAN sensors display system health (e.g. temperature and voltage), the performance data and statuses of logical and physical disk drives, and the statuses of cases, controllers, and power supplies. Data is queried by way of the Secure Shell (SSH) network protocol. A command line interface (CLI) must be present in the SAN to be able to monitor your storage area networks with SSH.

“We can all work with greater peace of mind knowing that our systems are constantly
being monitored.”

Markus Puke, Network Administrator, Schüchtermann Klinik, Germany

4 good reasons
to choose PRTG
as your SAN monitoring tool

Data security

Data security

The use of RAID technology makes storage area networks especially secure. But it is only by monitoring your SANs that you can provide your data with comprehensive protection against hardware errors and damage.



All storage area network values are displayed on an easy-to-read dashboard. Create automated reports for your co-workers and higher-ups. Customize the dashboard, as well as the alarm and reporting features.



PRTG automatically alerts you in the event of a storage error of if your SAN has reached its capacity limit, is about to crash, or can no longer be reached at all. To do so, PRTG uses the alarm of your choice: SMS, email, or push notification.

Data performance

Data performance

Thanks to PRTG monitoring, you can keep track of the performance of your storage area networks and ensure your co-workers are able to access SAN data without delays. This creates corporate efficiency, from the bottom up.
