What PRTG can do for your switch monitoring needs

Keep an eye on the status of your switch ports

When monitoring switch ports, administrators are up against some major challenges. They must be able to continually check for closed ports that should actually be open, as well as for potentially dangerous open ports.

With PRTG, you'll keep constant track of your switch ports and automatically receive an alarm if there is some unusual activity.


Optimize and boost your network performance

If a switch is stretched beyond its capacities, then it is sure to break down. Such a situation is both frustrating and unnecessary.

With PRTG, you are quickly informed of impending overloads and can upgrade the switch accordingly and also plan for more hardware resources – for more bandwidth capacity on your switches.


Analyze your network traffic capacities

Switch monitoring is not just about observing the status of your switches. It’s also important to understand the kind of traffic they are handling.

With PRTG, you gain insights into the data flowing through each switch, allowing for a comprehensive traffic analysis. These insights let you identify patterns, prioritize critical applications, and optimize bandwidth allocation.


Beyond switches: Get a holistic view of network connections

PRTG's monitoring capabilities go beyond tracking the health and performance of your network switches. The network monitoring tool also provides an overview of your entire vital network infrastructure including all critical connections and components.

This ensures that you have a properly working network environment and minimizes potential downtimes.


Preconfigured sensors for monitoring switch hardware & traffic to help you get 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.

SNMP sensors

PRTG comes with preconfigured SNMP sensors for the switches of well-known manufacturers. Check out, for example, the SNMP Cisco System Health sensor or the SNMP Dell Hardware sensor.


Packet Sniffer sensor

The Packet Sniffer sensor monitors the headers of data packets that pass a local network card using a built-in packet sniffer, and filters the traffic by IP address, protocol, and data type.


Flow (NetFlow, jFlow, sFlow, IPFIX) sensors

You can also easily monitor the traffic on switches from manufacturers such as Cisco and Juniper using, for example, preconfigured NetFlow v9, jFlow v5, or sFlow (Custom) sensors.

Switch monitoring: FAQ


1. What is switch monitoring?

Switch monitoring is the process of continuously observing and managing the performance, status, and activities of network switches. It allows network administrators to ensure switches are operating efficiently, identify potential issues before they escalate, and keep a tab on network traffic.

2. What are the advantages of switch monitoring?

Switch monitoring with PRTG offers multiple benefits:

  • Improved network performance: By keeping an eye on the traffic and performance metrics of a switch, you can identify and fix bottlenecks, ensuring smooth data flow across your network.
  • Enhanced security: By monitoring switch ports, you can detect unauthorized devices or activities, preventing potential security breaches.
  • Proactive problem resolution: Real-time monitoring helps detect issues early on, allowing for timely interventions before they escalate.
  • Efficient resource utilization: By understanding your switch traffic patterns and peak times, you can optimize your network and resource allocation.

3. How do I go about switch monitoring?

Many sysadmins resort to the command line for swift checks, such as verifying the availability of a particular network device (e.g., a switch). Nonetheless, expert monitoring delves deeper.

An advanced monitoring solution employs protocols like SNMP, NetFlow, and IPFIX to consistently oversee all your crucial network devices. PRTG equips you with multiple SNMP sensors, enabling you to initiate your monitoring immediately.

4. 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.
