OTel Export for DSH

DSH has cost dashboards, but no machine-readable export. This turns a dsh-token-audit JSON summary into OTLP/JSON metrics for Grafana, Langfuse, or any collector that accepts JSON.

It is a summary exporter: cost, tokens, sessions, calls, projected monthly, idle/peak, and per-model totals. It does not produce per-turn or per-tool spans.

Pipeline

dsh-token-audit --all --format json > audit.json
node bin/dsh-otel.mjs --input audit.json --output otlp.json

In DSH:

Use otel_export on audit.json, format=summary.

Metrics

• dsh.cost.cny
• dsh.tokens.input, dsh.tokens.cache_read, dsh.tokens.output
• dsh.sessions, dsh.calls
• dsh.cost.projected_monthly_cny
• dsh.cost.idle_cny, dsh.cost.peak_cny
• per model: dsh.model.cost.cny, dsh.model.calls, dsh.model.tokens.output

Boundaries

• No network: it writes JSON; your collector uploads it.
• No per-turn/per-tool spans, no live streaming, no dashboard.
• It inherits the audit's pricing; it does not re-price.
• Redact the audit before exporting if titles/paths are sensitive.
• OTLP/JSON only, not protobuf.
