PRODUCT OVERVIEW

5 problems you can solve with the PRTG ethernet monitoring tool

When working in an IT team – especially as a system admin – there’s nothing more nerve-wrecking and time-consuming than recurring problems (which could easily be solved if you could pinpoint the root cause of the problem). Raise the curtain for Paessler PRTG, your powerful network monitoring software and the solution to a lot of these issues.

Resolve IP address conflicts

Double allocation of IP addresses due to a DHCP server configuration error or a server failure are extremely annoying. With PRTG, you can monitor the availability and configuration of your DHCP server – simply use the WMI Service sensor or the DHCP sensor to easily solve your problems.

Prevent packet loss

Disconnects and loss of quality in VoIP or video calls are often related to packet loss or duplicate packets. PRTG offers various sensors like QoS (Quality of Service) One Way or QoS (Quality of Service) Round Trip so you can check jitter, packet delays, and more to get to the bottom of the problem.

Find defective ethernet ports

Have you experienced unexpected downtime or other issues around network management lately? And your ethernet configuration seems to be correct? With the Port v2 sensor you can check the TCP/IP ports of your router to get one step closer to the solution.

Discover bandwidth bottlenecks

Performance bottlenecks during peak-usage times due to high-demand applications can be a real bother. To monitor ethernet and find the bandwidth hog or adapt your network performance management, use PRTG for a deep-dive analysis of your bandwidth usage patterns in your entire network.

Ensure fast ethernet response times

Connecting to the internal DNS servers again takes forever and using simple online services is a test of patience? Real-time network monitoring with PRTG helps you to identify possible causes, for example if the CPU usage of a network component is too high or if there’s a problem with your database you should look into.

What ethernet monitoring looks like in PRTG

Diagnose network issues by continuously tracking ethernet traffic on your endpoints and in your on-premises network infrastructure. Show ethernet availability and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot duplicate packets, unexpected downtimes or outages, and unwanted network loops.

More than ethernet monitoring software: Improve your network performance management with PRTG

While ethernet bandwidth monitoring is an important part of any viable network management strategy, a powerful and easy-to-use, real-time monitoring software such as PRTG can give you so much more.

Improved network bandwidth reliability

With PRTG, you are prepared for all eventualities. Whether you want to get to the bottom of a network congestion, check your ethernet traffic or perform general ethernet troubleshooting – PRTG is the monitoring software of your choice.

Automated and customizable alerts

Whether it's a problem with your network devices, routers, or anything else, PRTG will alert you immediately with customizable notifications. Set individual error thresholds to trigger alerts when you need them, configure detailed alerting rules, and choose your preferred notification method such as email, SMS, or push notification.

Detailed monitoring dashboards

For ethernet monitoring tools to provide real value, they must not only be quick to install, but also work out of the box. To get you up and running immediately, PRTG installs quickly and offers an Auto-Discovery feature, as well as preconfigured dashboards (or maps in PRTG) and the ability to customize or create completely new ones.

Reliable data for improved IT security

Whether DDoS, ransomware, or the classic trojan horse –  network attacks on IT infrastructure have unfortunately become part of everyday life. PRTG is here to help you get the information you need to protect your IT by monitoring your critical security points and devices across your entire distributed network in real time.

Streamline your entire IT/OT operations

While you are using the SNMP Disk Free v2 sensor to check the space on your hard disks, and the free PRTG apps for iOS and Android to have a look at the latest data on the way to the server room, why not also check the OT network of your company’s production floor? Because with PRTG, you can streamline your entire IT/OT operations with one comprehensive monitoring software.

Ethernet Monitoring: FAQ

 

What is ethernet?

Ethernet is a common network technology. It facilitates the transmission of data over local area networks (LAN) and metropolitan area networks (MAN). It provides a standardized way for devices to communicate over a network, using a protocol that controls how the data is transmitted and ensures that the information arrives its destination safely and efficiently. It’s adaptable to both personal and professional environments and forms the backbone of most modern business networks.

What is ethernet monitoring?

Ethernet monitoring is the process of monitoring the health and performance of ethernet networks to ensure that they are operating efficiently and securely. By tracking real-time data such as bandwidth usage, network traffic, and device status, monitoring your ethernet helps to identify and resolve issues that can affect network connectivity and performance.

How do I identify ethernet performance problems?

Identifying ethernet performance issues within a network involves monitoring various metrics such as network traffic, bandwidth utilization, the health of network devices including routers, switches and repeaters, and security-related parts like the firewall.

Ethernet performance monitoring software such as PRTG provides real-time visibility into these metrics, allowing IT professionals to detect anomalies that may indicate problems such as network congestion, bandwidth bottlenecks, or failing hardware.

How will ethernet problems affect my network?

Ethernet problems can result in network downtime, reduced data transfer speeds, and overall network instability. These problems can disrupt business operations, resulting in lost productivity, negative financial impact, and potential security risks. Persistent problems can also drain IT resources, as teams spend more time troubleshooting and less time on future projects and strategic initiatives.

How does PRTG solve ethernet bandwidth monitoring challenges?

PRTG streamlines ethernet bandwidth monitoring by providing a comprehensive set of tools to continuously track network performance. This includes features like:

  • Monitoring ethernet traffic in real-time to quickly pinpoint the source of problems
  • Packet sniffing – the detailed examination of data packets to identify anomalies or bottlenecks
  • LAN health monitoring, which continuously checks the health of the local area network to prevent and resolve problems in a timely manner
Can PRTG be used as an ethernet performance test tool?

Yes, PRTG can be used as an ethernet performance test tool. Thanks to the large number of specialized ethernet monitoring sensors, data such as uptime monitoring or bandwidth consumption can be collected and visualized.

Since PRTG is also an advanced bandwidth calculator and network reporting tool, you can quickly find out where bottlenecks are and how they affect your ethernet performance. You always have the right software to improve your network performance strategy and to monitor your entire IT infrastructure.

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.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
