4 reasons why our PRTG data center monitor is the best fit for you

Avoid downtime with 24/7 data center monitoring 

Everything in your data center is running smoothly? Great! In Paessler PRTG, you can see at one glance that there are no problems in your data center and focus on other areas of your work.

Every minute of downtime in your data center can cost your company thousands of dollars. Thus, high availability of all your data center components is vital for your business success.

What’s more: with PRTG, you can prevent errors and downtimes even before they occur. If a component in your data center infrastructure fails, PRTG shows you the cause of the error so that you can quickly fix it.

Customize thresholds, alerts & notifications

Once you have set up your data center monitoring in PRTG, you can sit back and relax. If any issue or error occurs in your data center, PRTG instantly alerts you via highly customizable alerts and notifications. You can not only set custom threshold values but also choose the way you want to be informed – whether by email, SMS, push notification, Teams or slack message, and more.

Visualize your data on structured maps & dashboards

The more complex your data center, the harder it is to know if everything works as expected. PRTG provides you with a central overview that consolidates any data center monitoring data in easy-to-read dashboards. You can also create your own, customized maps and dashboards that show you all important metrics in one view – even of distributed data centers.

Get detailed statistics and useful reporting

PRTG not only monitors your data center in real time but also records all important performance data. You therefore get detailed information about your data center whenever you want it: How high was the overall uptime during the last 12 months? What about bandwidth usage?

With the comprehensive reporting system of PRTG, you can also identify data usage trends in your data center. This way, you can decide more easily where more capacity is needed or where you can save resources. Data center monitoring reports help you to:

  • Be proactive by detecting problems bevor they affect you customers
  • Avoid downtime and costly system outages
  • Fulfill your service level agreements (SLA)
  • Provide better quality of experience to your customers

Monitor all aspects of your data center

Data centers are way more than a bunch of computers in a room. Thus, data center monitoring goes beyond traditional IT and network monitoring. In fact, a data center can be seen as an entity composed of three main blocks, which you can all monitor with PRTG.

IT and network infrastructure

Monitor your entire data center infrastructure, including all computers, routers and switches from vendors like Linksys or Cisco, servers, firewalls, and virtual environments.

Applications and services

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













Environmental parameters

Most data centers host critical information and run applications that businesses and individuals rely on for their daily work. As a result, it is crucial to maintain an optimal data center environment. This involves monitoring metrics such as temperature, humidity, smoke, the energy supply, and even physical security in server rooms.

Discover our preconfigured PRTG data center monitoring sensors

Here are some examples of sensors that can be used for data center monitoring with PRTG:



 i How PRTG defines sensors

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 center monitoring: FAQ


1. What is data center monitoring?

Data center monitoring refers to the process of collecting and analyzing data about the performance and operation of a data center's physical infrastructure, systems, and applications. The main goal of data center monitoring is to ensure that the data center is operating efficiently and effectively and to detect any potential issues before they become major problems.

2. Are there best practices for data center monitoring?

  • Set up your monitoring environment: Install a data center monitoring tool like PRTG and integrate all your services, devices, applications, and metrics that you want to monitor. With the PRTG auto-discovery, this can be automatically done within minutes.
  • Set up a notification system: To be alerted immediately when an issue arises, set up notifications and alarms in your monitoring tool. In PRTG, you can define thresholds for each monitoring metric and if a threshold is breached, you are immediately alerted.
  • Review and analyze your collected monitoring data regularly. This helps to identify trends, areas for improvement, and gives you hints when to upgrade your infrastructure.

3. Can I monitor distributed data centers with PRTG?

You can monitor distributed data centers with PRTG using remote probes or setting up multiple PRTG servers. All monitoring data that you collect from your distributed data centers can be visualized on one single dashboard, which makes it way easier to keep track of your data center infrastructure and environment.

4. 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.
