Monitor your network, your way

With PRTG, you have many technologies for monitoring your local area network at your disposal. You can use SNMP, for example, which is easy to set up and only requires a minimum of resources. To monitor network traffic,  you can use packet sniffing to analyze individual data packets, NetFlow for monitoring the data flow on Cisco devices, or technologies like IPFIX, sFlow, or jFlow.


Distributed networks are no problem

Distributed networks are no problem

You can use remote probes to monitor separate LANs with only one PRTG license; even WANs which can span several countries (or continents). PRTG can also provide you with a comprehensive overview of your virtual private network (VPN).

3 use cases for PRTG LAN monitor


 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.

Better availability

Your LAN must be completely operational at all times and therefore, your network devices need to be reachable. A router switches off at night without your knowledge? Not with PRTG! Our LAN monitoring solution monitors the uptime of your network round the clock – for example, with the SNMP System Uptime sensor.

Better security

Firewalls are attacked countless times each and every day. As an administrator, you must be notified immediately if your firewall is down. A Ping v2 sensor displays the availability of your firewall in real time. If there is an issue with your firewall, PRTG alerts you directly via customizable notifications, for example, via SMS, e-mail, or push notification. PRTG monitors firewalls from different vendors such as Fortinet or SonicWall.

Better performance

Your company or organization is experiencing continuous growth? An increase in the number of employees leads to a greater amount of network traffic and even more devices. This automatically results in bandwidth bottlenecks. With PRTG, you can comprehensively monitor the health and performance of all your devices, for example, with the SNMP Hardware Status sensor.

Keep an eye on these 5 pillars of LAN monitoring with PRTG








In many industries, employees need high-performance workstation computers, such as those used for video or 3D processing. Workstation functionality is thus paramount to productivity. From hard disk to CPU to memory: with PRTG, you're always in the know.



All network data passes the routers in your IT infrastructure – they are the hubs of your LAN. That’s why it’s important that you monitor your routers round the clock. The sooner you see that one of your routers is overloading, the quicker you'll be able to take countermeasures.



As distribution nodes, your switches can be under heavy strain. All it takes is one single switch to overload for your entire LAN network to become more slowly or even fail completely. This is why you should never lose sight of your switches with PRTG.




PRTG monitors all types of servers and the corresponding server hardware. It supports all major manufacturers like Cisco, HPE, Oracle, or Dell. Whether database, mail, or web servers: PRTG provides you with a unified overview of your server monitoring data so that you can be sure that your servers run smoothly at all times.



How much LAN bandwidth do you have? Which devices and applications consume most of the available bandwidth? With PRTG, you'll have your finger on the pulse of your bandwidth usage – which also means that you can ensure the hassle-free operation of your company’s infrastructure.

FAQ: LAN monitoring 


1. What is a LAN?

A local area network, or LAN, is a network that connects different network devices in a single physical location. A wide area network, or WAN, by contrast, spans distributed geographical locations.

2. Is LAN monitoring really necessary?

In professional business settings, network outages can have severe consequences. Employees and customers are unable to access, for example, the company LAN or online shop, which results in an unnecessary waste of resources. That’s why administrators must be able to immediately determine the cause of an interruption and what is needed to get the network back up.

3. Why should you invest in LAN monitoring?

There are several reasons why you should monitor your LAN, for example:

  • To ensure the availability of all physical and virtual devices on your network
  • To have a detailed overview of your network and an inventory of every device connected to it
  • To detect connectivity problems that might impact business continuity before they even arise
  • To detect performance bottlenecks that can affect the productivity of your employees
  • To better allocate network resources

4. What to look for when choosing a LAN monitoring software?

There are 5 main features you need to look out for when choosing a LAN monitoring tool, and PRTG covers all of them.

  • The capability to monitor many different devices, systems, and parameters at once
  • A centralized display of information for better observability
  • Customizable alerts and automated notifications when alerts are triggered
  • Native reporting features that can be adapted as required and set to run automatically
  • A free trial period so you can attest how the tool works with your infrastructure

5. What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
