toolmemcheck

Toolmemcheck is a cross-platform utility for profiling and monitoring the memory usage of other tools and processes. It helps developers detect memory leaks, excessive allocations, and fragmentation in command-line utilities, services, and runtimes. The tool can launch a target program or attach to a running process and collect metrics such as resident set size, virtual memory size, peak allocations, and allocation counts over time. Measurements can be sampled or collected continuously, and results are published as reports suitable for local analysis or CI workflows.

Measurements can be sampled or collected continuously, and the results are published as reports suitable for local analysis or CI workflows. Key features include low runtime overhead, multi-language plugin support, and flexible output options such as JSON, CSV, or human-readable summaries.

The system uses a modular architecture with a core engine, platform-specific data collectors, a reporter, and optional plugins. Users typically invoke toolmemcheck with a command to monitor or with a PID to attach to an existing process.

Example usage: toolmemcheck --duration 60s --output memcheck.json -- path/to/tool arg1 arg2. Alternatively, attach to a running process by PID and observe for a defined interval. Outputs are designed for dashboards or archival review.

Toolmemcheck runs on Linux, Windows, and macOS and is released under an open-source license. Ongoing development is community-driven. Limitations include measurement overhead, partial visibility for certain runtimes, and OS-specific differences in memory accounting; it should be used as a diagnostic aid rather than a definitive correctness check.
