Process Monitor for Linux is a system tracing tool that captures and displays syscall activity across processes on Linux systems.
The tool addresses the need to observe what system calls processes are making, which is essential for debugging, performance analysis, and understanding application behavior. It works by tracing syscall activity and presenting the results through an interactive terminal user interface, allowing developers to filter and examine events in real time. The tool can also operate in headless mode to write captured events to a database file for later analysis.
Developers working on Linux systems who are familiar with the Windows Procmon tool will find this a direct equivalent for their platform. It suits scenarios where understanding process behavior at the syscall level is necessary, such as troubleshooting application issues, analyzing performance bottlenecks, or investigating system interactions. The tool supports filtering by process ID and specific syscalls, making it practical for focused investigation rather than requiring analysis of all system activity.
The project maintains an active build pipeline with automated testing. Development follows a structured contribution process documented in dedicated guidelines, and the maintainers actively solicit feedback through multiple channels including GitHub issues and feature requests. The codebase is written in C and requires standard build tools and SQLite development libraries to compile.
