SystemTap is a powerful scripting tool used for monitoring and analyzing the performance of Linux systems. It allows users to write scripts that can probe the kernel and user-space applications, providing insights into system behavior without requiring extensive modifications to the code. This makes it easier to diagnose issues and optimize performance. With SystemTap, developers and system administrators can gather detailed information about system calls, memory usage, and CPU performance. It operates by dynamically inserting probes into the running kernel, enabling real-time analysis. This capability is particularly useful for troubleshooting complex problems in production environments.
