How PRTG helps to eliminate network faults

Ping monitoring to detect device errors

PRTG automatically sets up initial ping monitoring during installation. Ping sensors display the availability of all network devices, including routers and switches which can cause bottlenecks. This can help you more quickly detect the source of errors.

24/7 server monitoring to avoid crashes

Is an error or malfunction affecting your database servers, web servers, or mail servers? PRTG monitors your servers around the clock, so you’ll be notified quickly in the event of a server crash or failure.

SNMP monitoring to find connection errors

Your connections keep going down – but you have no idea why. Our SNMP sensors provide an immediate overview of your network traffic, while packet sniffing allows for a more in-depth analyses. And with our QoS sensors, you can even monitor quality of service.

 

Your network fault management software at a glance – even on the go

Set up PRTG in minutes and use it on almost any mobile device.

 

PRTG comes with all the features you need, plus more your IT infrastructure won't want to live without.

Network fault management: FAQ

 

What’s the difference between a network error and a network fault?

There are many different ways to say “network error.” Besides “error,” you might find “bug,” “fault,” or “failure.” It all depends on whether the term is being used by a system administrator, software developer, or software tester.

Network error

Countless errors occur in every network. Here are some examples of error codes for network problems: 400, 1106, 410, 503, 410, and 503. Depending on the severity of the error, the sysadmin may be required to take action at once. On the other hand, in the world of software development, an “error” occurs when a developer makes a mistake because of a misjudgment or misunderstanding.

Network fault

Sysadmins consider “faults” as general network errors that lead to a malfunction or crash. Fault network management was created to combat such errors. In software development, a “fault” is seen as an anomaly in code that leads to an error.

What’s the difference between network management, fault management, and network monitoring?

Network management” encompasses any task that an IT manager performs with regard to their network infrastructure, and includes error, configuration, invoice, performance, and security management. There are open-source as well as proprietary tools for each of these tasks. The right network management system depends, among other things, on the size of the network and the demands of the IT manager.

The term “IT fault management” is used in a broader context. It involves identifying, diagnosing, and evaluating errors in network operations. These errors can include program errors, operating errors, or certain human errors. IT fault management is used to come up with measures for keeping errors to a minimum. Network monitoring plays an important role in this process.

"Network monitoring” is a passive way of monitoring a network. Sensors automatically monitor the hardware, applications, and traffic in your network. If a malfunction or a critical error occurs, an alert is sent immediately so the IT manager can take action at once. A network monitoring tool like PRTG saves time, prevents crashes, and lets sysadmins focus on other important tasks.

What are the benefits of network fault management?

Network fault management is a critical aspect of network management that focuses on identifying, diagnosing, and resolving network issues to ensure seamless performance. The benefits of effective network fault management include:

  • Improved network uptime: Rapid identification and resolution of network issues reduce downtime, ensuring that the network operates with high availability.
  • Enhanced performance: By proactively detecting and addressing faults, network performance remains optimized, minimizing disruptions to end-users.
  • Proactive issue detection: Fault management tools can identify potential problems before they escalate, allowing administrators to take preventive action.
  • Reduced operational costs: Automating fault detection and resolution processes decreases the need for manual intervention, saving time and resources.
  • Enhanced security: Detecting anomalies and unexpected changes in network behavior can help identify security breaches or unauthorized access attempts.
  • Better user experience: Reduced latency, fewer disruptions, and high network reliability contribute to a better experience for end-users.
  • Compliance with service level agreements (SLAs): Effective fault management ensures that organizations meet their SLAs, maintaining trust and credibility with customers and partners.

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.
