From 50e1f593af88da1593541deac016aa489e321cf8 Mon Sep 17 00:00:00 2001 From: amcheste-ai-agent <278991699+amcheste-ai-agent@users.noreply.github.com> Date: Tue, 2 Jun 2026 10:41:51 -0400 Subject: [PATCH] feat(observability): pipeline-aware metrics, dashboard, and printer column MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Knowledge-work teams operate at the granularity of pipeline stages and produced artifacts, not just tokens and cost. v0.8.0 needed observability to match — operators should be able to see, in a glance, which stage a team is in, how long stages take, what came out the other end, and whether delivery to external systems worked. Metrics (new, `kagents_` prefix to match the rebrand) - kagents_team_pipeline_stage_active{team,namespace,stage} — gauge, 1 while Running, 0 elsewhere. Stack-by-stage in Grafana for the classic flight-status view across many teams. - kagents_team_stage_duration_seconds{team,namespace,stage} — histogram, observed once at the Running → Completed edge. Exponential buckets starting at 30s, matching the existing team-duration histogram. - kagents_team_artifacts_produced_total{team,namespace,teammate} — counter, increments once per ArtifactStatus appended; idempotent across reconciles because the dedup guard on Status.Artifacts is the gate. - kagents_team_delivery_success_total / _failure_total {team,namespace,type} — counters, one increment per delivery attempt from executeDelivery. The existing `claude_*` metric family stays untouched so existing dashboards keep working; this PR adds five `kagents_*` series rather than renaming. A future major release can sync the prefixes. Reconciler wiring - updatePipelineStatus emits the stage gauge on every reconcile (Running → 1, otherwise 0) and observes duration exactly once at the Completed transition (gated on prevPhase != Completed). - recordTeammateArtifacts increments the artifact counter inside the dedup-checked append path. - executeDelivery records success vs failure per target alongside the existing event emission. Status / kubectl - New `Stage` printer column (priority=1, so `kubectl get agentteams` shows it when -o wide / on wide-enough terminals). Sources status.pipeline.currentStage. Dashboard - Pipeline section on the team detail view: progress bar over completed/total, list of stages with their phase chip and teammates-ready ratio. - Artifacts section listing name, producing teammate, and source path; renders only when status.artifacts is non-empty. - New pipelinePercent template helper, fully covered (nil, zero, half, full, overflow clamp). Tests - internal/metrics rose to 100% coverage. Five new tests on the new helpers + the names guard extended to the kagents_ prefix. - internal/dashboard rose to 73.9% with the new helper tests. - internal/controller existing pipeline-status tests still green. Docs - docs/explanation/operations.md metrics table extended with the five new series and a paragraph explaining the dual-prefix situation.
