  "message": "Add statsd microbenchmark and fix a crash in LogEvent\n\n+ We should benchmark the core functions in the critical path.\n     1. LogEvent parsing\n     2. Log matching\n     3. Event processing in various metrics\n     ....\n\n+ Using microbenchmark, we can quantify the optimization we do in the future.\n\n    ---------------------------------------------------------\n    Benchmark                  Time           CPU Iterations\n    ---------------------------------------------------------\n    BM_LogEventCreation       4772 ns       4705 ns     145738\n\nTest: make -j64 statsd_benchmark\n\nBug: 72242322\n\nChange-Id: I43aa704ffdc7cd21e02ef9038eff66ca7022dbfb\n",
