Which tool can help monitor server performance in real-time?

Application Performance Monitoring (APM) tools are specifically designed to track and analyze the performance of software applications in real-time. These tools provide valuable insights into various metrics such as response times, transaction rates, error rates, and resource utilization. By continuously monitoring the system, APM tools help administrators identify performance bottlenecks, diagnose issues, and optimize application performance proactively. This capability makes them essential for maintaining and improving server performance, enabling businesses to deliver seamless user experiences and maintain high service levels.

Other options do not provide the necessary features for effective server performance monitoring. Spreadsheet software lacks real-time data collection and analysis capabilities for monitoring server metrics. Standard email services focus on communication and do not have functionalities for performance tracking. Basic text editors are primarily designed for editing text and are not equipped to handle performance monitoring tasks.
