The need for remote monitoring

Nowadays, IT and Network infrastructures are more distributed than ever before. Companies have their devices and services distributed over local networks, branch offices, customer networks (in case of MSP), data centers and in the cloud.

The IT Administrator’s wish would be to centrally monitor all distributed networks/infrastructure in one console/location. Another wish would be a monitoring solution to monitor all distributed devices and services. PRTG Network Monitor aims to make the life of IT Admins easier, by answering the above requirements, and a lot more.

PRTG Network Monitor is a unified monitoring solution that will allow you to centrally monitor your local and remote infrastructure out of the box.

  • Unified monitoring - one tool to monitor your local and remote networks
  • 24/ 7 monitoring through PRTG
  • Get notified in time, hence avoiding costly downtimes
  • Check how your infrastructure is performing in real-time
  • Address bottlenecks before they cause problems

One tool to monitor your local and remote networks

Unified Monitoring

Unified Monitoring

PRTG is an agentless unified monitoring solution. On the one hand, each device or service which has an IP address, or is reachable over IP and talks a protocol (SNMP, HTTP, WMI, xFlow, etc) can be monitored by PRTG probes (see below). On the other hand, there is no need to install agents on monitored devices.

Local Probe

Local Probe

Upon configuration, PRTG creates the first probe automatically, called the Local Probe. It runs on the same machine as the PRTG core server and monitors all devices in your LAN, using the sensors you have configured.

Remote Probe

Remote Probe

You can extend monitoring to your distributed networks by installing one or more Remote Probes. These remote probes allow you to monitor different sub-networks that are separated by a firewall from your PRTG on premises core server, to keep an eye on remote locations, and are useful in several other scenarios. All you need is a computer on which you can install your remote probe (see requirements).

5 reasons to work with Remote Probes

There are several situations that make it necessary to work with remote probes in the same LAN or in remote locations. Among these situations are the following:

PRTG in the cloud

PRTG in the cloud

You run a PRTG in the cloud instance and want to monitor your local network.

Several locations

Several locations

You have more than one location and you need to make sure that services are available from all locations.



Your network is separated in several LANs by firewalls, and the local probe cannot monitor specific services across the firewalls.

Secure Connection

Secure Connection

You want to monitor systems in a secure network, and you need a secure connection between the PRTG server and this network.

Distribution of load

Distribution of load

Offload the PRTG core server by taking some load and distribute it over one or more PRTG remote probes.

Remote monitoring made easy!




























One-click installer

One-click installer

With its one-click installer, a PRTG Remote Probe can be installed and configured in just a few clicks. The installer contains all the configuration data needed to connect to PRTG core server.

Initiate connection

Initiate connection

After the installation, the probe initiates a connection to the PRTG core server, gets the configuration and the list of devices that need monitoring, and then starts right away with monitoring your remote infrastructure and sending the results to the PRTG core server, over an SSL-encrypted connection. Moreover, you will need to open only one port in your firewall, which will be used by the remote probe connection.

Send results

Send results

Furthermore, the remote probe does only send results to the PRTG core server, and not all monitoring traffic. Thus, network links between the Remote Probe and the core server are not overloaded.

Send monitoring data

Send monitoring data

PRTG Remote Probes can also be configured to work with clustered PRTG installations. The probe sends monitoring data to both master and failover server. The main benefit is that your remote sites are being monitored even when one of the cluster node fails.



Thanks to its auto-update, PRTG updates remote probes automatically each time the core server is updated to a newer version. This will help you to save time, because you will not need to update each probe separately.

Remote monitoring for Managed Service Provider (MSP)






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.

MSP Solution

MSP Solution

Each license of PRTG Network Monitor can be used as a fully functional MSP solution. You simply install the core server at your site, and then monitor your customer's sites via remote probes. This allows you to monitor different customers at the same time with a single license/core server installation of PRTG.

Access Rights

Access Rights

Moreover, PRTG Network Monitor offers a credential-based system. Depending on your customer's needs you can define different access rights: either give them full access to their probes, groups or sensors, so they can manage their monitoring on their own or you just give them read-only access so that they can see their own monitoring data but not change any settings.



PRTG monitors your customer’s infrastructure 24/7. You can be notified via various types of notifications (e.g. SMS, email, Pager, Push notifications) to react quickly. This alert can be sent to your customer, too. Also, escalation levels can be defined.



You can also create regular reports for you and for your customers, containing statistics of events, outages, uptime etc. PRTG will not only ensure you get alerted in time, it also gives you the opportunity to create easily understandable dashboards which quickly give you an overview of your local and remote sites.
