NAS monitoring:
PRTG secures all your network storage devices


 iBandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps). It refers to the transmission capacity of a connection and is an important factor when determining the quality and speed of a network.

A network solution for big data

A network solution for big data

In the age of big data, companies are faced with the need to store and process ever-increasing amounts of data. In order to keep hardware investments to a minimum and avoid storing memory on local computers, these companies often go for a network-based solution.

NAS performance monitoring

NAS performance monitoring

With network-attached storage (NAS), central network storage devices provide network clients with independent storage capacity, the amount of which can be adjusted according to client needs. This storage capacity, furthermore, can be shared across the entire company network. PRTG monitors capacity and performance to reduce malfunctions – or ideally, to prevent them from happening at all.

The seamless distribution of storage space

The seamless distribution of storage space

Thanks to PRTG NAS monitoring, you can ensure storage space is distributed across your network in an efficient manner. PRTG monitors hardware, system statuses, physical and logical disks, network connections, and input/output operations to guarantee the safe storage of data. Our monitoring tool even monitors virtual storage systems backups files, file content, and folders.

Identify sources of error

Identify sources of error

NAS monitoring lets you both identify bottlenecks which impede access to your NAS data and provide network clients with just the right amount of storage capacity. You can also record suspicious traffic which might be a sign of an attack on your data. Finally, you will ensure backups are performed successfully and therefore avoid unpleasant surprises further down the line.

PRTG measures the overall bandwidth values of a network environment. This makes good sense, for if the network goes down, then it will be impossible to use network-attached storage.

PRTG is equipped to handle all your data.

How NAS monitoring with PRTG works


 i What 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 is like a local file system

NAS is like a local file system

NAS systems are connected to the network directly and do not require dedicated PCs or servers. NAS file systems appear on employee computers as local file systems. Transmission protocols such as NFS, SMB, and CIFS are used to access and store files in the connected network.

PRTG Auto Discovery feature

PRTG Auto Discovery feature

Thanks to its built-in Auto Discovery feature, PRTG is able to recognize all the NAS devices that are connected to your network. Auto Discovery uses device templates for the NAS systems of several manufacturers, including LenovoEMC, Buffalo, QNAP, Synology, and NetApp. Pre-configured sensors are set up automatically, depending on the hardware that is found. Additional sensors can also be configured manually. If you’re unable to find the desired sensor for your NAS monitoring, PRTG lets you create custom sensors which will query the required data via SNMP for example.

QNAP monitoring with special PRTG sensors

QNAP monitoring with special PRTG sensors

QNAP offers a wide range of NAS solutions to meet a variety of different user requirements: personal and business solutions, high-availability and industry solutions, and monitoring and administration solutions. Its network-attached storage devices provide storage space which allows for a stable infrastructure in small, medium, and large corporations.

QNAP’s NAS solutions not only meet storage requirements, but also offer services and features that can help increase productivity. QNAP has a Turbo NAS for every business function and every budget. Some of the characteristics of these systems include LCD displays, cache acceleration, resilience in extreme conditions, hot swapping, SAS support, rackmount, high-speed data transmission, and fanless designs.

PRTG has developed special sensors to monitor each of these functions.

6 good reasons to
choose PRTG as your
NAS monitoring tool

Plan storage capacity

Plan storage capacity

Data collected during PRTG NAS monitoring helps you determine the storage capacity requirements of your company. You will therefore have an important say in the planning and acquisition of additional memory.

Recognize errors, prevent crashes

Recognize errors, prevent crashes

By monitoring network storage devices and the traffic created by them, you’ll identify problems faster and prevent costly downtime. Set up an alarm system by defining the threshold values which, when exceeded, will trigger an alarm. Thanks to the "unified monitoring” of PRTG, you can monitor much more than just your storage systems.

Receive automatic notifications
