Observability as Code: Why SREs Are Writing PromQL and Not Just Dashboards

Dashboards are no longer enough.

In 2026, SREs aren’t just looking at graphs - they’re encoding reliability logic directly into queries, alerts, and pipelines.

This shift is called Observability as Code (OaC).

Why Dashboards Fall Short at Scale

Traditional dashboards:

  • Are manually curated
  • Drift over time
  • Don’t enforce correctness
  • Visualize symptoms, not intent
  • Fail during incidents when you need precision

When infrastructure is ephemeral and distributed, static dashboards become screenshots of the past.

What “Observability as Code” Really Means

Observability as Code means:

  • Treating queries, alerts, and SLOs as versioned code
  • Storing PromQL, LogQL, TraceQL in Git
  • Reviewing observability changes via pull requests
  • Automatically validating observability logic in CI/CD

If it’s not version-controlled, it’s not reliable.

Why PromQL Becomes the Source of Truth

PromQL expresses intent, not presentation.

Examples:

  • Burn rate detection
  • Error budget consumption
  • Latency SLO breaches
  • Saturation and backpressure patterns
  • Cardinality-safe aggregation

One PromQL rule can power:

  • Alerts
  • SLO dashboards
  • Automation triggers
  • Root-cause correlation

Dashboards just render the result.

SRE Use Cases That Demand Code, Not Clicks

Modern SRE teams use PromQL to:

  • Detect slow burns before alerts fire
  • Encode service reliability objectives
  • Correlate infra + app + traffic signals
  • Reduce alert noise with math, not heuristics
  • Automate incident classification

These cannot be click-built consistently.

How CI/CD Changes Observability

With OaC:

  • Observability breaks builds when queries are wrong
  • Alert logic is tested before deploy
  • Changes to metrics schemas fail fast
  • New services ship with SLOs by default

Observability becomes part of the delivery pipeline, not an afterthought.

Beyond Metrics: Logs & Traces as Code

The same model applies to:

  • LogQL for error patterns
  • TraceQL for latency breakdowns
  • Event correlation logic
  • Deployment-aware observability

SREs now write cross-signal queries instead of clicking across tools.

Where KubeHA Fits

KubeHA turns Observability as Code into actionable intelligence by:

  • Correlating PromQL, LogQL, TraceQL outputs
  • Connecting telemetry with Kubernetes events & config changes
  • Explaining results using LLM reasoning
  • Surfacing why signals changed - not just that they changed

Queries find the signal. KubeHA provides the story.

🔚 Bottom Line

Dashboards don’t scale. Code does.

In 2026, SREs:

  • Write PromQL to encode reliability
  • Version observability logic
  • Automate detection and response
  • Use dashboards only as a visualization layer

Observability as Code isn’t advanced - it’s the minimum bar for modern reliability engineering.
