Fault management is a process used in network and system administration to identify, isolate, and resolve issues that disrupt normal operations. It involves monitoring systems for errors or failures, analyzing the root causes, and implementing solutions to restore functionality. This ensures that services remain reliable and minimizes downtime. Effective fault management often employs tools and techniques such as network monitoring software and alert systems to detect problems early. By maintaining a proactive approach, organizations can enhance their overall performance and user satisfaction while reducing the impact of faults on their operations.
