LSP Startup Statistics

codescout records LSP cold-start timing to .codescout/usage.db and surfaces it in the project dashboard under “LSP Startup”.

What is recorded

Each cold start records:

  • Language — which LSP server was started
  • Reason — new_session, idle_evicted, lru_evicted, or crashed
  • Handshake duration — time for the LSP initialize round trip
  • First response duration — time for the first real tool request (symbols, hover, etc.)

Viewing the data

Open the dashboard (codescout dashboard --project .) and look for the “LSP Startup” section. It shows per-language averages/p95 and a recent event list.

Limitations

  • first_response_ms may be null if no tool call followed the cold start in the same server process.
  • Events are only recorded when the project root is known at startup time.
