Why data center monitoring is essential

Data centers are at the heart of every IT infrastructure and mission critical in every company. Due to technical evolution, the complexity of a data center’s infrastructure keeps increasing, and should it fail, businesses are often left inoperable. Monitoring your data center with PRTG will allow you to:

  • Ensure 24/7 monitoring of all your data center through PRTG
  • Check how your infrastructure is performing in real time
  • Avoid expensive outages
  • Address bottlenecks before they cause problems
  • Know trends in data center for a better capacity planning
  • Provide better Quality of Experience (QoE) to your customers
  • Save time and money

Data center monitoring with PRTG

At Paessler, data center monitoring goes beyond the traditional IT and Network monitoring.
In fact, from monitoring perspective a data center can be seen as an entity composed of three main blocks:


Network infrastructure

IT and Network Infrastructure

This includes network devices (switches, routers, etc. from vendors like Linksys or Cisco), servers, firewalls, load balancers, virtual environments, etc.

Applications and services

Applications and Services

It includes all applications and services which are hosted in your data center. For example, web servers (IIS, Apache, NGINX), SQL Servers (Microsoft SQL Server 2005-2016, Oracle, MySQL, PostgreSQL), mail server (Exchange, IMAP, POP3, SMTP), web applications (websites, portals), backups, security, and customer specific applications.

Data center environment

Data center environment

It covers all aspects around data center facilities. For example, physical sensors (which monitor temperature, humidity, smoke, and movements in server rooms), security cameras, energy supply, access control, etc.

All-in-one Monitoring of heterogeneous infrastructure


The data center infrastructure is composed of heterogeneous devices, applications and services from different
manufactures or providers. Hence you need one unified monitoring solution to monitor them all.

PRTG Network Monitor makes network monitoring easy


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.

One Tool for everything

One Tool for everything

With PRTG you can monitor the classic infrastructure, the data center environment, and services & applications at the same time and within one tool. PRTG offers more than 250 predefined sensors out of the box for suppliers like Dell, Citrix, HP, IBM and many more. But, don’t worry if you’re using other brands, PRTG is agentless, and therefore makes it easy for you to integrate your own device through custom sensors. Every object which has an IP address and which supports a monitoring protocol (SNMP, WMI, HTTP, etc) can be monitored by PRTG.

Get automatically alerted

Get automatically alerted

Once you start monitoring your data center in real time, you’ll never have to worry about bottlenecks, exceeding your bandwidth, or fluctuation in temperature in your data center. All you need is to set thresholds and PRTG will alert you each time something is not working as expected, thanks to its very flexible and powerful notifications mechanism. Besides, PRTG learns what is normal for your infrastructure and it will automatically detect unusual behaviors and alerts you accordingly.


Data reporting for better service quality

Moreover, the PRTG data reporting will allow you to see trends in your data center and help you to decide where more capacity is needed. By doing so, you will be:

  • Be proactive (by detecting problems bevor they affect you customers)
  • Avoid downtime
  • Fulfil your Service-Level-Agreements (SLAs)
  • Provide better quality of experience to your customers
