Capabilities

Observability

Operational observability for distributed control: state, health, and diagnostics that connect UI, backend, and edge.

Capabilities overview

Design intent

Use this lens when adopting Observability: define success criteria, start narrow, and scale with safe rollouts and observability.

  • Unified timelines reduce time-to-diagnosis across teams
  • Stable IDs + rollout state make incidents debuggable
  • Alerts should detect degradation, not just total failure

What it is

A distributed automation system needs end-to-end visibility: runtime health, fleet status, and telemetry tied back to versions and deployments.

Design constraints

  • Unified timelines reduce time-to-diagnosis across teams
  • Stable IDs + rollout state make incidents debuggable
  • Alerts should detect degradation, not just total failure

Architecture at a glance

  • Edge emits health/events/telemetry with stable IDs (device/resource/app/deploy)
  • Store-and-forward buffers protect evidence during outages
  • Backend correlates timelines to snapshots so debugging becomes “find the diff”
  • This is a capability surface concern: visibility is required to scale safely

Typical workflow

  • Define the minimal signal set: deployment state + runtime health + adapter health + telemetry
  • Create dashboards that answer: what is running? is it healthy? is it correct?
  • Use correlated timelines (events + telemetry + rollout state) to debug
  • Codify alerts for restart bursts, buffer saturation, flapping, and drift

System boundary

Treat Observability as a capability boundary: define what success means, what is configurable per site, and how you will validate behavior under rollout.

Example artifact

Event timeline (conceptual)

t=00:00 deploy:start snapshot=snap_... device=edge-12
t=00:12 runtime:healthy resource=forte-1
t=00:20 adapter:connected protocol=modbus endpoint=pump-1
t=01:10 telemetry:ok points=128 gap=0s
t=03:40 alert:staleness point=pump_speed > 5s

What it enables

  • Faster incident response with clear traces
  • Rollout safety gates based on health
  • Confidence when changing logic and configuration

Engineering outcomes

  • Unified timelines reduce time-to-diagnosis across teams
  • Stable IDs + rollout state make incidents debuggable
  • Alerts should detect degradation, not just total failure

Quick acceptance checks

  • Define standard health signals for runtime, adapters, and deployments
  • Ensure timelines can join telemetry + events + deployments via stable IDs

Common failure modes

  • Telemetry gaps from buffer saturation or upstream auth/network issues
  • Clock skew and batching causing out-of-order timelines
  • “Everything is green” while behavior is wrong (mapping/data-quality issue)
  • Over-alerting: noisy signals that hide real regressions

Acceptance tests

  • Verify the deployed snapshot/version matches intent (no drift)
  • Run a canary validation: behavior, health, and telemetry align with expectations
  • Verify rollback works and restores known-good behavior

How teams typically turn this capability into outcomes.

Key takeaways

  • Unified timelines reduce time-to-diagnosis across teams
  • Stable IDs + rollout state make incidents debuggable
  • Alerts should detect degradation, not just total failure

Checklist

  • Define standard health signals for runtime, adapters, and deployments
  • Ensure timelines can join telemetry + events + deployments via stable IDs
  • Create incident views: “what changed?”, “what failed first?”, “what recovered?”
  • Alert on restart bursts, drift, buffer saturation, and connectivity flaps

Common questions

Quick answers that help align engineering and operations.

What’s the minimum observability needed to operate remotely?

Deployment status + runtime health + connectivity/adapter health + basic telemetry timelines tied to snapshot IDs.

Why do incidents feel hard without good observability?

Because you can’t correlate symptoms to changes. Version-correlation is what turns “mystery behavior” into a solvable diff.

How do we reduce time-to-diagnosis?

Use consistent IDs, record state transitions, and keep a single timeline view that joins deployments, health, and telemetry.
