PRTG connects 'Monitoring' with 'Mapping'
That's the difference between PRTG and other tools

Network Scanner and Mapping Tools

Pure network scanners or network discovery tools detect the network with all its components and deliver results in the form of a list. This information can then be used for creating network charts and maps using network mapping software.

But this requires a significant amount of time-consuming, manual work. Furthermore, only static maps can be created this way which themselves have no other utility except the pure network overview.

Network Mapping Tools

In addition to the combination of scanners and mapping tools, there also exists complete network mapping solutions. These scan the network and integrate the identified devices directly in network diagrams and maps - so called 'auto-mapping' generating the network maps automatically.

Integrated network mapping solutions are clearly superior to the combination of network scanners and mapping tool when it comes to usability, but the automatically generated maps often not fall-short in terms of legibility: the overwhelming number of network devices and connections confuse the clarity of the results instead of producing a clear overview. Here, a manual touch up is required - if the solution allows for this action. A further disadvantage is the limitation to scanning and mapping which does not deliver data concerning the actual condition of devices.


Network Monitoring Software

Network monitoring tools with the mapping option, as opposed to pure network mapping solutions, or the combination of network scanners and mapping tools, deliver information on the availability and condition of detected components. Additionally, on network traffic and network performance beyond simply 'discovering and mapping the network topology'. Many of these solutions promise further assistance by 'Auto-Mapping': via network discovery, identified network devices such as switches, routers, firewalls, as well as servers or applications, are displayed in automatically-generated network maps.

However, the outcome of such auto-maps is often unsatisfactory. Many devices and even more connections are displayed one-dimensionally on over-sized maps. This might be acceptable as a 'one-off' inventory, but such cards are cluttered and unhelpful in daily use for troubleshooting and network planning.


PRTG Network Monitor:
Network Monitoring with Map Editor

PRTG offers a compromise between the combination of network scanners and a network mapping solution. It balances monitoring software with auto-mapping, truly offering the best of both systems. 

The finely tunable 'Auto-Discovery' detects all IT components from switches, routers and firewalls, servers and applications, to storage systems and virtual servers. 

All of these components can be integrated quickly and easily into clear network maps using the simple 'drag & drop' built-in map editor. Using custom HTML, multi-layer maps can be generated making it possible to drill-down through multiple layers while 'error searching' without hindrance.

With the PRTG dashboard-designer, you can create and design your own unique network maps.

The Sunburst View in PRTG

In addition to clear and easily creatable maps, PRTG provides a surplus against the suite of pure network scanning and mapping tools: PRTG maps show not only devices and connections, but also deliver information on their status.

Adding a building plan as wallpaper shows each device's location.

Simultaneously, the PRTG Sunburst-View provides the entire network topology at a glance.

Der PRTG Sunburst View lässt sich einfach in PRTG-Maps integrieren und zeigt sämtliche Netzwerk-Komponenten und deren aktuellen Zustand auf einen Blick.

The PRTG Sunburst View can be easily integrated into PRTG maps and displays all network components and their current status at a glance.


Network Diagrams

Another advantage of the PRTG-map editor is the ability to create custom network diagrams for different audiences:

For example, one map that shows all network devices for the network administrator, while the IT manager's 'overall' map uses the sunburst-view to show the entire network at a glance - including the state of all components.
