Your network at a glance: 5 sensors for getting started



 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.

Ping Sensor

Ping Sensor

The Ping Sensor checks the reachability of all the devices in your network. During the installation of PRTG, your local range of IP addresses gets pinged and basic initial monitoring is configured automatically. Learn more about ping monitoring here.

SNMP sensors

SNMP sensors

Our SNMP sensors let you quickly identify which applications and servers are using the most bandwidth. PRTG comes with preconfigured SNMP sensors for a variety of manufacturers, including Cisco, Dell, and HP. Discover more on SNMP monitoring here.

Packet Sniffer Sensor

Packet Sniffer Sensor

The Packet Sniffer Sensor lets you perform in-depth network traffic monitoring. You can filter traffic using a number of different criteria, including data type, IP address, and protocol. As a result, you'll uncover usage trends and other valuable information regarding your network. Find out more about packet sniffing here.

NetFlow sensors

NetFlow sensors

NetFlow sensors monitor Cisco devices such as switches and routers. PRTG also comes with other Flow sensors (sFlow, jFlow) and IPFIX.

DNS Sensor

DNS Sensor

The DNS Sensor monitors and indicates the response times of your DNS servers. If a DNS server is non-responsive or malfunctioning, this sensor will pick up on it automatically and display an alarm message.

greg campion 14 one forth

Hey Greg, can you give me an example of how PRTG works with network utilities?

Ping sensors are probably the most important elements of any network monitoring. They must be set up correctly, particularly with regard to your connections. When monitoring a virtual machine, it makes sense to place the ping in connection to its host. If the host crashes, you will therefore not be notified for each and every virtual machine connected to it. Furthermore, ping sensors can be good indicators of whether a network path to a host or the Internet functions properly, especially in high-availability or failover scenarios.”

Greg Campion is a system administrator at PAESSLER AG


Network utilities in various systems

 i Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable. The ping command sends a request over the network to a specific device. A successful ping results in a response from the computer that was pinged back to the originating computer.

Mac network utility

Mac network utility

The Mac network utility is called “Network Utility.” This program displays information on your network connections, including the IP address, the speed and number of sent and received data packets, and the number of transmission errors. Network Utility also comes with Netstat, Ping, Lookup, Traceroute, Whois, Finger, and Portscan.

Windows network utility

Windows network utility

Windows also comes with network programs. These programs vary depending on the Windows version you are using. Here too you can run a ping, test connections and ports, or use nslookup to check your DNS information.


Distributed networks: Network utility software PRTG is also a good choice

Distributed networks:
A lot of work for your IT department

Many companies have several sites or branches which are managed centrally by one IT department. Among other things, malfunctions can cause a lot of work for administrators, who must travel to the particular site to clarify the problem.


Advantage of PRTG:
Convenient and efficient

Convenient and efficient With your PRTG license, you can even monitor geographically distributed networks. This works via remote probes that are set up in the remote network and remain in constant contact with the PRTG Core Server.


Decentralized monitoring:
Case study

The Swiss company Bystronic monitors its worldwide network with PRTG. The company’s headquarters are located in Switzerland. It has three further production and development sites in Germany and China, and sales and service branches in over 30 different countries. Bystronic uses PRTG (and nothing else) to centrally monitor its entire network.

White paper
on remote probes

In this free white paper, you can read more about distributed network monitoring. You’ll also learn exactly how remote probes work. For example: did you know a remote probe can also be placed behind a firewall? The probe monitors your network from “the inside,” and sends information to the PRTG server via an encrypted connection. Find out more in the white paper.


Agent-based vs. agentless network monitoring

 iA server is a computer or system that provides resources, data, services, or programs to other computers, known as clients, over a network. In theory, whenever computers share resources with client machines they are considered servers. There are many types of servers, including web servers, mail servers, and virtual servers.

Agent-based monitoring

Agent-based monitoring

Those looking to set up network monitoring have the choice between two types of tools: agent-based and agentless. With agent-based tools, software agents are installed on each piece of hardware that needs monitoring, allowing for in-depth analysis. These tools can be quite costly, however, especially in larger networks.

PRTG is an agentless software

PRTG is an agentless software

PRTG is based on an agentless process. The network is monitored centrally from one main server. Software does not need to be installed on the target computers. With PRTG, an agentless architecture is even possible for distributed networks. In such a case, remote probes are used (see “Distributed networks").


Problem diagnosis tools: The limits of PRTG

What PRTG can do

PRTG keeps a constant eye on your network. SNMP sensors show you how much bandwidth is being used by your devices and applications, while Flow sensors and packet sniffing let you take a closer look at data packets.

What PRTG cannot do

If you wish to analyze the content of individual data packets, then you’ll need a special diagnostic tool. There are many such tools on the market. PRTG is purely a monitoring tool.


Investing in network monitoring: PRTG pays for itself in no time

The costs for a one-year PRTG license usually pay for themselves within a few weeks.

More on network monitoring

Router monitoring

With PRTG, you can monitor the bandwidth usage, network activities, and error messages of your routers. To do so, choose from several preconfigured sensors which work with a variety of different manufacturers, including Cisco, Dell, and HP.

Server monitoring

PRTG monitors all your servers: DNS, mail, MySQL, and many more. You therefore get a monitoring tool for all the main hardware in your network. And you can configure the PRTG alarm system to be promptly notified in the event that this hardware malfunctions.

Port monitoring

PRTG monitors open and closed ports. This will help you improve the security of your network. Often ports are only used temporarily and then forgotten. But open ports represent a danger, as they can be gateways for Trojan horses.
