Description: Active monitoring is a proactive approach to overseeing systems and applications, designed to detect issues before they impact performance or availability. Unlike passive monitoring, which relies on historical data collection, active monitoring involves executing tests and gathering metrics in real-time. This allows system administrators to identify and resolve problems proactively, thereby optimizing operational efficiency. Active monitoring tools may include monitoring TCP/IP networks, tracking DNS logs, and assessing the performance of operating systems on various platforms. Additionally, it integrates into virtualized environments where constant monitoring is required to ensure the stability of virtual machines. Network segmentation also benefits from active monitoring, as it allows for real-time identification of bottlenecks and vulnerabilities. In operating systems, active monitoring is crucial for maintaining system integrity and performance, ensuring that applications run without interruptions. In summary, active monitoring is essential for the efficient management of complex technological infrastructures, providing a clear and real-time view of the status of systems and applications.
