dsh-o11y-plugin

dsh-o11y-plugin

Unified plugin-dimension observability (trace / log / metric) for deepseek-harness (dsh).

中文文档

Overview

dsh ships session-level OTel telemetry but exposes no metric or plugin-scoped observability to plugins. dsh-o11y-plugin converges that gap: it registers global OpenTelemetry providers so any plugin using the standard @opentelemetry/api exports traces, metrics, and logs through a single, consistently configured pipeline, and it bridges dsh session telemetry into OTel logs. It is intended for plugin authors who want standard, community-compatible observability without implementing OTel per plugin.

Compatibility

Item	Value
DSH compatibility	@deepseek-ai/dsh 0.1.0-rc.6–rc.8 (optional bridge hook unchanged; no dsh service deps)
Runtime dependency	@deepseek-ai/cordis 4.0.1 only
Last verified	2026-08-20 (unit tests against @deepseek-ai/cordis 4.0.1)
Node	^22.19 || >=24
Profiles	headless, web

Built on the official OpenTelemetry Node.js SDK, the same dependency family as dsh's session-telemetry-otel.

Install / Uninstall

# install
dsh plugin --profile web add github:fly3366/dsh-o11y-plugin

# disable for one profile
dsh plugin --profile web remove dsh-o11y-plugin

# or disable at runtime via config: enabled=false

The plugin is stateless; removal requires no data cleanup.

Quick start

dsh plugin --profile headless add github:fly3366/dsh-o11y-plugin
# point exports at a collector (optional; silent without one)
OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4318 dsh --profile headless "say hi"

Any plugin that calls trace.getTracer(...) / metrics.getMeter(...) / logs.getLogger(...) from @opentelemetry/api is then exported automatically. deepjit is the reference consumer, emitting pipeline counters and GenAI (gen_ai.*) LLM spans.

Configuration

The same knobs are exposed as an o11y namespace in the dsh Web settings UI (via @deepseek-ai/dsh-settings), so they can be viewed and edited there; they persist and apply on the next dsh start. This no-ops on dsh versions without the settings service.

A reference Web settings card (client half) is developed on the wip/settings-ui branch; dsh does not yet let external bundles inject into the web client composition, so it is not shipped on main.

Key	Default	Description
enabled	true	master switch
serviceName	'' (→ OTEL_SERVICE_NAME → dsh-plugin)	OTel resource service.name
endpoint	'' (→ OTEL_EXPORTER_OTLP_ENDPOINT → http://localhost:4318)	OTLP/HTTP endpoint
enableTraces / enableMetrics / enableLogs	true	per-signal toggles
metricExportIntervalMs	60000	periodic metric export interval
bridgeSessionTelemetry	true	bridge dsh session telemetry into OTel logs

Sensitive: no credentials are read or stored; only the optional OTLP endpoint is network-facing.

Permissions & data

• Files: none written; all telemetry is in-memory until exported.
• Network: OTLP/HTTP to the configured endpoint only; silent drop when no collector is reachable.
• Credentials: none.
• User data: session-telemetry records are observed in-memory (when bridging) and forwarded as OTel logs; nothing is persisted by this plugin.

Troubleshooting

• No collector at the endpoint → batches are dropped silently (expected).
• Export errors → surface via OTel diag; verify endpoint and collector availability.
• Roll back with dsh plugin --profile <p> remove dsh-o11y-plugin or set enabled=false.

Development

npm install
npm run typecheck
npm test
npm run build

Contributions welcome; keep the OTel SDK dependency family aligned with dsh's session-telemetry-otel for community compatibility.
