  • Replacing the orchestrator dropped the provider turn, session, runtime event, and orchestration command metrics, so most of the T3 Code Grafana dashboard went empty with no sign anything had regressed

…again

Deleting the old orchestration stack dropped every t3_provider_* and
t3_orchestration_* metric with it, leaving the Grafana dashboard empty
with no signal that anything had regressed.

PR Summary

Low Risk
Changes are additive instrumentation around existing dispatch and provider flows; no business-logic alterations beyond metric recording and exports.

Overview
Restores orchestration and provider observability that went missing after the orchestrator replacement, so Grafana dashboards can populate again.

Adds command dispatch metrics (t3_orchestration_commands_total, t3_orchestration_command_duration, t3_orchestration_command_ack_duration) on thread orchestrator dispatch and project command commit—ack duration spans from before the per-thread lock through durable commit. Effect worker increments t3_orchestration_events_processed_total per claimed effect type.

Re-wires provider metrics: session start/stop/recover on ProviderSessionManager, turn send duration/count on RunExecutionService, interrupt/steer/restart on ProviderTurnControlService, and runtime events (plus turn.terminal.failed) on ProviderEventIngestor. Several counters/timers are exported from Metrics.ts for shared withMetrics / attribute helpers.

Tests assert Metric.snapshot for each instrumented path.

📝 Walkthrough

Walkthrough

The server now records metrics for orchestration effects and commands, provider runtime events and sessions, and provider-turn operations. Tests inspect metric snapshots for these measurements.

Changes

Server observability

Layer / File(s) Summary
Metric definitions
apps/server/src/observability/Metrics.ts
Exports orchestration and provider lifecycle metrics, and exports providerTurnMetricAttributes.
Orchestration metrics
apps/server/src/orchestration-v2/EffectWorker.ts, apps/server/src/orchestration-v2/EffectWorker.test.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/Orchestrator.control-reads.test.ts, apps/server/src/project/ProjectService.ts, apps/server/src/project/ProjectService.test.ts
Records processed effects, command counts and durations, and acknowledgment durations. Tests inspect the corresponding metric snapshots.
Provider event metrics
apps/server/src/orchestration-v2/ProviderEventIngestor.ts, apps/server/src/orchestration-v2/ProviderEventIngestor.test.ts
Records provider runtime events by driver and event type. Failed terminal events also record turn.terminal.failed. Tests inspect both event metrics.
Provider session metrics
apps/server/src/orchestration-v2/ProviderSessionManager.ts, apps/server/src/orchestration-v2/ProviderSessionManager.test.ts
Records start or recovery metrics for new sessions and stop metrics for released sessions. Reused sessions are excluded.
Provider-turn metrics
apps/server/src/orchestration-v2/ProviderTurnControlService.ts, apps/server/src/orchestration-v2/ProviderTurnControlService.test.ts, apps/server/src/orchestration-v2/RunExecutionService.ts, apps/server/src/orchestration-v2/RunExecutionService.test.ts
Records provider-turn counts for interrupt, restart, steer, and send operations. Send operations also record duration. Tests inspect metric snapshots.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Suggested reviewers: juliusmarminge

Merge Risk: 🔵 Low · up to 7cb54

A repeated session open can be missing from lifecycle metrics in this narrow case. Correct the per-evaluation flag before relying on complete session counts.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 7cb54

The changes restore aggregate operational measurements without an established change to access privileges or session ownership. No security regression was identified. Protection of exported measurements and their use in security monitoring remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated new data flow reaches shared server metric state with aggregate operational labels. It does not establish new tenant-specific data exposure or privilege propagation. Downstream exporter and backend exposure cannot be bounded from the supplied deployment evidence.

Trust Boundaries and Controls

  • observed — The changed open path retains existing-session attachment restrictions and registry-based adapter lookup. Metric emission receives the selected adapter's driver rather than MCP credential information or caller-provided session identity.

Resilience and Maintainability Implications

  • observed — Credential reservation release, failure cleanup, interruption handling, and protection of credentials held by replacement sessions remain separate from metric flags. The shared measurement wrapper returns successful results or propagates the original failure cause after recording measurements.
