**Category:** Engineering  
**Tier:** POWERFUL  
**Description:** Design comprehensive observability strategies for production systems including SLI/SLO frameworks, alerting optimization, and dashboard generation.

## Overview

Observability Designer creates production-ready dashboards, alert configurations, and monitoring strategies across the three pillars (metrics, logs, traces).

**When NOT to use → slo-architect.** For SLO/SLI design with error-budget math, multi-window burn-rate alerting thresholds, and SLO review gates, route to `slo-architect` — it is the authoritative skill for that half. This skill's `slo_designer.py` produces a quick scaffold only. This skill's lane: dashboards (`dashboard_generator.py`) and alert-noise reduction (`alert_optimizer.py`).

## Quick Start

```bash
# Dashboard spec (Grafana JSON + docs) for a service
python3 scripts/dashboard_generator.py --service-type api --name payments --criticality critical --role sre --format grafana -o dashboard.json --doc-output dashboard.md

# Analyze an existing alert config for noise, duplicates, and coverage gaps
python3 scripts/alert_optimizer.py --input alerts.json --analyze-only --report alert_report.json
# ...then emit the optimized config once the report is reviewed:
python3 scripts/alert_optimizer.py --input alerts.json --output alerts_optimized.json

# Quick SLO scaffold (hand off to slo-architect for the real error-budget work)
python3 scripts/slo_designer.py --service-type api --criticality high --user-facing true --service-name payments -o slo_scaffold.json
```

**Verification loop:** after deploying optimized alerts, track the report's noise metrics for one on-call rotation — if the actionable-alert ratio didn't improve, re-run `--analyze-only` against the live config and iterate. Import the generated dashboard into Grafana and confirm every golden-signal panel renders with live data before closing the task.

## Core Competencies

### SLI/SLO/SLA Framework Design
- **Service Level Indicators (SLI):** Define measurable signals that indicate service health

- **Service Level Agreements (SLA):** Establish customer-facing commitments with consequences
- **Error Budget Management:** Calculate and track error budget consumption
- **Burn Rate Alerting:** Multi-window burn rate alerts for proactive SLO protection

### Three Pillars of Observability

- **Interactive Elements:** Template variables, drill-down links, and annotation overlays
- **Performance:** Sub-second render times through query optimization

### Alert Design and Optimization

- **Severity Levels:** 
  - **Critical:** Service down, SLO burn rate high
  - **Warning:** Approaching thresholds, non-user-facing issues
