trace-processor

# Trace Processor The `trace_processor` extension launches a long-running FastMCP server wrapping Perfetto's trace processor capabilities, allowing seamless interaction with trace files (`.pftrace`, `.perfetto-trace`, `.pb`). ## Writing PerfettoSQL and Schema Analysis For comprehensive guidance on querying traces, utilizing standard library modules, and schema structures, refer directly to the native Perfetto AI skills inside `third_party/perfetto/ai/skills`: - **Querying Traces**: See the [perfetto querying traces](/third_party/perfetto/ai/skills/perfetto/infra-references/querying.md) skill. - **Common SQL Tables**: Explore standard table definitions such as `slice`, `thread`, `process`, `sched_slice`, and `track`. - **Perfetto Standard Library**: Utilize standard library modules like `slices.with_context` by starting queries with `INCLUDE PERFETTO MODULE`. ## Official Perfetto References - Trace Processor reference: <https://perfetto.dev/docs/analysis/trace-processor> - Generated SQL Tables: <https://perfetto.dev/docs/analysis/sql-tables> - Standard Library Documentation: <https://perfetto.dev/docs/analysis/stdlib-docs>
