Running an otelview

One binary, four processes' worth of job: OTLP receivers on :4317 (gRPC) and :4318 (HTTP), storage, the web UI and query API on :4319, and an MCP endpoint at /mcp on that same port. No cluster, no JVM, no sidecar.

otelview                      # in-memory, UI on http://127.0.0.1:4319
otelview --storage duckdb     # persist to ./otelview.duckdb
otelview -c otelview.yaml     # everything else
otelview --print-config       # every default, as YAML — the reference

--print-config is the honest source of truth for what a version accepts. Reach for it before writing config from memory.
