Network Fault Management with PRTG

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.

“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.

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.

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.
