Main challenges of monitoring
large IT infrastructures



Larger setups often create higher loads on monitoring solutions. Performance problems can lead to falsified monitoring results and annoyed users, which may increase the risk of failures and outages. PRTG is built to deal with these kinds of loads and offers best practices to avoid performance issues. 


A monitoring solution is a central component of most IT environments. This means that compatibility with other vendors is essential. PRTG is vendor-agnostic and its flexible API gives you the power to build custom solutions that meet your exact needs.

Distributed environments 

Few large IT environments run a single network but are made up of multiple closed networks instead. PRTG offers an easy, affordable way to manage distributed monitoring along with configuration support to ensure you still have a complete overview and avoid responsibility conflicts.


Main issues of established monitoring solutions 



 Limited monitoring scope

Many IT monitoring providers that focus on the middle market have solutions to monitor 
single aspects of the IT environment like servers or network performance, which are available individually or as a suite.

 Complex and expensive

To have an overview of all IT systems, you need monitoring suites that consist of multiple tools. This increases the complexity for IT teams and makes licensing complicated and expensive

 Reduced feature set

Other solutions reduce features to a minimum and avoid functionality that affects performance



The larger the IT environment, the more complex it is to manage. 
PRTG keeps monitoring simple and gives you 
insight into your IT systems in a matter of minutes.


Monitoring with PRTG is simply different


Ease of use

PRTG provides the best user experience possible. This is visible in the user-friendly interface as well as in the simple licensing structure. The initial setup is straightforward and you get instant feedback from the system.

Feature set 

PRTG includes all functionality in every license. This includes everything from IT infrastructure and xFlow-based traffic monitoring, to monitoring of virtual, cloud, and hybrid environments, including IoT.


The licensing structure of PRTG is as easy as PRTG is to use. Each PRTG license includes the entire feature set, no modules, and no add-ons. PRTG offers two licensing models for larger installations: the perpetual PRTG XL1 license and the PRTG Enterprise Monitor subscription license.  


PRTG integrates with most analysis tools using an API and predefined templates. It acts as a data collector and early warning system, helping to identify failures and to show where further analysis is needed.

Close partnerships with leading IT vendors and with established players in the ITOM market ensure seamless integration.

PRTG is best practice for large monitoring setups

distributed environments     large single setup


Monitoring distributed environments 


IT teams in medium-sized or large enterprises are often distributed across multiple datacenters, offices, legal entities, business units, or areas of responsiblity, each with their own team. 

Implementing a single monitoring solution has advantages: 

  • Consistent company-wide monitoring solution
  • Option to have a centralized overview 
  • Cost saving and easy licensing 

Each team manages its own, independent infrastructure running one or more PRTG servers exclusively for their environment. With the remote probe feature, each single PRTG installation can monitor multiple sites or segments. Distributed monitoring is not an additional feature. It is part of the extensive feature set of every PRTG license.

For a centralized overview, there are two options:

  1. PRTG Desktop for a detailed overview
  2. ITOps Board (part of Paessler PRTG Enterprise Monitor) for a more sophisticated service-level overview, incorporating data from other ITOps tools, and with SLA reporting and troubleshooting using automated incident workflows.

Centralized monitoring for large environments 


Monitoring large IT environments with a centralized monitoring solution requires a clear strategy.

We advise customers to segment their monitoring in a way that fits the organization and to scale horizontally, for example in terms of geography or functional teams. This improves performance by balancing the workload and gives teams more autonomy with their own dedicated monitoring server. It also avoids complex setups and the need for roles and rights management. 

Advanced overview with ITOps Board

PRTG Enterprise Monitor includes ITOps Board, which provides a service-level, central overview of all single installations. ITOps Board gathers information from multiple PRTG servers, categorizes them by business services, adds automated alert management, and provides SLA monitoring and reporting.

PRTG licenses for large environments

Paessler offers two alternatives for monitoring large environments.



PRTG XL1 is a perpetual license which allows for a single PRTG server installation. You can run about 10,000 sensors per PRTG server.


  • Perpetual licensing
  • One PRTG server installation, with each license
  • Licensing based on the number of PRTG servers

PRTG Enterprise Monitor

PRTG Enterprise Monitor is subscription-based. There is no limitation on the number of PRTG servers or sensors.

PRTG Enterprise Monitor is a good fit for very large setups or if the scenario requires multiple PRTG server installations, like for distributed or heavily segmented environments.

  • Subscription licensing
  • Unlimited PRTG server installations
  • Licensed by number of sensors
  • Includes ITOps Board


Sensors are the basic monitoring elements of PRTG. One sensor usually monitors one measured value
in your network such as the traffic of a switch port, the CPU load of a server, or the free space of a disk drive.
On average, you need about 5-10 sensors per device or one sensor per switch port.


“The challenge for large organizations is to successfully monitor tens of thousands of elements in real time, and ensure that they are performing well, without drowning in a flood of information. ITOps Board solves the problem by providing that essential consistency, especially since PRTG “oversees” other monitoring solutions in an overall merging of dashboards that organizes all the information, from the global level to the most granular. It's a real help in our ongoing quest for simplification.”
