TASK-044: Capture Dashboard Screenshots

Part of: Prometheus Monitoring Implementation (Phase 4 - Grafana Dashboards)
Parent Issue: #1062
Priority: Low
Effort: S

Description

Capture screenshots of each of the 4 Grafana dashboards for use in documentation. This requires a running Grafana instance with a Prometheus datasource populated with runner metrics data.

Dashboards to Screenshot

Dashboard	File	UID
Runner Overview	runner-overview.json	github-runner-runner-overview
DORA Metrics	dora-metrics.json	github-runner-dora
Performance Trends	performance-trends.json	github-runner-performance
Job Analysis	job-analysis.json	github-runner-job-analysis

Acceptance Criteria

• Screenshot captured for each of the 4 dashboards showing panels with sample data
• Screenshots saved to docs/images/ or equivalent directory
• Screenshots referenced in docs/features/GRAFANA_DASHBOARD_METRICS.md
• Images optimized for web (compressed PNG or WebP)

Prerequisites

• Running Grafana instance (v9.0+) with Prometheus datasource
• At least one runner generating metrics data for realistic panel content
• All 4 dashboard JSON files imported into Grafana

Notes

This was deferred during Phase 4 implementation because it requires a live environment with real metrics data. Can be completed when a monitoring stack is available for testing.
