Three reasons for taking stock of your network
How do I find all my network devices? Sooner or later, every administrator must tackle this question.
In general, there are three reasons for taking stock of your network with a network discovery tool:
Network inventory
Administrators perform regular inventories in their companies. These inventories are not only done to get an overview of the network, but also for security reasons: An inventory will let you see if unwanted private devices are connected to your network.
Network expansion
When a company grows, so does its network. Many administrators are faced with the task of gradually expanding their networks. When doing so, network devices must be routed correctly to ensure the network remains stable and efficient.
Network costs
Increasingly, accounting departments are also keeping an eye on networks. It is important that all costs associated with network devices, maintenance, and licenses be recorded. To do so, administrators must have an overview of their hardware and software. Taking stock of the network can help.

Six good reasons
to choose PRTG
to monitor your network devices
Automatic stock taking
The PRTG Auto Discovery feature makes it easy to take stock of a network. This feature will automatically find all the network devices within an IP address range, and then integrate them into your monitoring.
Discovery of new devices
When opening PRTG for the first time, new devices will be detected and set up automatically. PRTG lets you create your own timetable: run the discovery automatically, either daily, weekly, or monthly. Each time, you’ll receive a ticket and an e-mail. And that means you’ll be able to keep a constant eye on what’s going on in your network.
Nonstop network monitoring
PRTG monitors your network 24 hours a day, 365 days per year - and not just at irregular intervals. You’ll therefore be able to discover those devices which may have been turned off during a one-time scan.
Alerts when the network malfunctions
At the slightest problem, you’ll be notified at once. Our alerts enable you to act quickly and avoid more serious disruptions. The alarm system is individually customizable.
Cross-locational network discovery
PRTG makes it easy to discover and monitor network devices that are spread out over several different locations. The centralized monitoring of distributed sites functions via remote probes, which run as a Windows service on a server in each of the respective locations.
Overview of all network devices
Each network device is set up by PRTG in a device tree. A simple and easy-to-understand dashboard illustrates the status of your network and of each individual device by way of a traffic light system. The dashboard is available on your desktop, or as an app for when you’re out of the office.
Your monitoring dashboard might look like this!

“Thanks to PRTG, we no longer need to worry about our network. We can sit back and relax knowing that powerful software is checking hundreds of network devices every 30 seconds. PRTG is so reliable that we almost always forget it is there – until we receive a message that something is wrong.”

How the PRTG Auto Discovery feature works, in three steps
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.

The Auto Discovery feature provides for the quick and convenient detection of all your network devices. PRTG automatically sets up devices in the network tree, and then equips them with sensors. Auto Discovery is described in detail in the PRTG manual. This is how it works:
Step 1
Enter the IP address range within which PRTG should search for network devices. Then launch the Auto Discovery feature; PRTG will use ping to find all the devices located within this IP range.
Step 2
Next run a scan to identify the types of devices which were found. Appropriate sensors will be created automatically. To do so, PRTG uses SNMP, WMI, and other protocols.
Step 3
All devices found by PRTG are then set up in a device tree. PRTG uses a number of device templates for this process. Whether Microsoft, Cisco, Dell, or Juniper: Corresponding devices are available for all the big manufacturers.
Quick results
PRTG sets up your network monitoring automatically and within minutes. You can fine-tune this initial monitoring over time. And while the runtime of Auto Discovery depends on the size of the designated IP range, the number of devices found, your network connection, and some other latency factors, once it is launched there is nothing else for you to do except adjust a few of its settings (such as “credentials”).

Six handy PRTG sensors
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.
Ping Sensor
The Ping Sensor verifies the availability of each and every device in your network. One of the most commonly used PRTG sensors, the Ping Sensor also displays ping time. The Cloud Ping Sensor is also used frequently. More on ping monitoring
SNMP sensors
SNMP sensors show you which applications are putting the most strain on your servers and bandwidth. SNMP is extremely reliable and takes up very little system load. More on SNMP monitoring
WMI sensors
For Microsoft devices, you can use our WMI sensors. The “System Information” feature, which is built into an extra tab, provides information on Windows systems, installed hardware and software, and much more. More on WMI monitoring
Packet Sniffer Sensor
The PRTG Packet Sniffer Sensor monitors the data traffic in your network, and can filter according to mail traffic, file transfer traffic, and infrastructure traffic, among others. More on packet sniffing
NetFlow sensors
The NetFlow protocol is mainly supported by Cisco routers and Cisco switches. PRTG supports all NetFlow versions. More on NetFlow monitoring
jFlow sensors
jFlow lets you monitor Juniper Networks hardware, among others. Here too you can configure devices especially for PRTG. It features a high degree of similarity to NetFlow5. Find out more about our jFlow sensor.

Detect network loops with PRTG
A network or switching loop can have a negative impact on the performance of your network. Such a loop may even lead to an outright network crash. The PRTG Packet Sniffer and NetFlow sensors will help you identify network loops, by highlighting the frequent appearance of duplicate data packets, for example. These sensors monitor incoming data packets, and filter traffic according to IP addresses, protocols, and data types.
“Hey Dirk, what do you think about network monitoring?”
“Without network monitoring, it can easily take several hours to locate a network error, such as identifying a router which isn't working properly. Costs can quickly pile up due to unused man days. With a monitoring service, the amount of downtime can be minimized and in many cases even proactively eliminated. With our PRTG monitoring tool, we hope to simplify the job of administrators so they can go about their work efficiently and with less stress.”
Dirk Paessler, founder of Paessler AG
Network scanners vs. PRTG:
Similarities and differences
Network scanners
Many administrators are in search of simple network scanners or tools that are 100% dedicated to network discovery. In such cases, it’s not about setting up monitoring, but discovering available devices as quickly and easily as possible. We too have used these tools in the past, such as “Angry IP Scanner,” when our company moved into its new offices.
Network monitoring
PRTG is a comprehensive network monitoring tool. Device discovery is the first step to the setting up of monitoring. PRTG offers considerably more than a simple network scanner. With PRTG, you can monitor servers, databases, websites, and much more. PRTG comes with pre-configured sensors for a number of different manufacturers, including Cisco, HP, and Dell.
Complementary tools
PRTG should not be seen as a rival to a simple scanner. Each is used in different circumstances. PRTG is convenient for taking over the tasks of scanner tools. On the other hand, some situations call for a simpler tool, such as for a short test when you don’t need detailed monitoring but only a quick overview.
