Observability — workers, grains and sagas

Generated from the architecture model

This page is rendered from model/**/*.yaml by tools/docs_model during mkdocs build. Edit the YAML, not this page; hand-written design lives on the linked service, platform and plane pages.

  • MetricRuleEvaluator (AlertRuleService): Evaluates metric-threshold rules against the backend on a schedule and fires or resolves instances.
  • Notifier (AlertRuleService): Delivers notifications for fired alerts through the Studio and connectors with receipts.
  • ProjectionRebuilder (DashboardService): Rebuilds run projections from Run Control's journal and producers' events after a restore or on request.
  • OverviewAggregator (DashboardService): Recomputes overview metrics per subject and window from run projections.
  • ProposalGenerator (FeedbackService): Clusters feedback, drift and failed evaluations per asset and drafts proposals with evidence and an expected effect (structured profile); never applies anything.
  • DatasetSnapshotter (FeedbackService): Builds dataset snapshots from harvested tasks and curated additions and stores them as artifacts.
  • SuiteRunner (QualityScoreService): Executes the tasks of a suite as Factory runs under the evaluation project, collects per-task metrics and computes the verdict against thresholds and the baseline.
  • DriftMonitor (QualityScoreService): Compares production outcome statistics per release with its evaluated scores and raises drift.
  • SloEvaluator (SloService): Evaluates every active objective from projections and metrics, computes burn rates and emits breaches and recoveries.
  • HealthCollector (SloService): Collects host health from the HealthChecks aggregator and the hosts' probes and updates the rollup.
