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.
