C++ Log Parser & Profiler

Command-line tool to parse large log files and compute stats:

• Top-K error messages by frequency
• Latency histogram (ms buckets)
• Simple RAII scoped timer to profile hot paths

Build

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j
./build/logprof --help

Run example

./build/logprof sample.log --top 5 --latency-col 3 --delimiter ','

Tests

cmake -S . -B build -DENABLE_TESTS=ON
cmake --build build -j
ctest --test-dir build --output-on-failure

Notes

• Uses std::string_view for zero-copy tokenization.
• Accepts CSV-like logs; adjust --latency-col to your column (0-based).
