Historical Analysis is the system health page at /settings/system-health/history that displays 30-day trend charts and period-over-period comparisons for key platform performance metrics: Largest Contentful Paint (LCP), API response time, and API error rate.

​
Overview

The page fetches 30-day metric histories via useHistoricalMetrics for LCP and API response time, and computes period comparisons (week, month, quarter) via usePeriodComparison for LCP, API response time, and API error rate. A performance report (weekly/monthly/quarterly) is generated via usePerformanceReport. Users can export metrics using ExportMetricsDialog and view peak usage via PeakUsageCard. The parent system health route is /settings/system-health and requires platform.system_health.manage.

​
Who it’s for

Requires permission platform.system_health.manage.

​
Before you start

  • You must hold platform.system_health.manage in your role.
  • Metrics are populated by the platform’s observability pipeline — if no data appears, confirm with an SME that the pipeline is active.

​
Steps

  1. Navigate to Settings → System Health → History (/settings/system-health/history).
  2. Review the 30-day trend charts for LCP and API response time.
  3. Select a comparison period (Week, Month, or Quarter) to see period-over-period deltas.
  4. Review ComparisonCard panels for each metric showing current vs. prior period values.
  5. Use the Export button to open the metrics export dialog and download data.
  6. Review the Peak Usage card for high-traffic periods.

​
Key concepts

LCP (Largest Contentful Paint) — a Core Web Vital measuring perceived load speed. Tracked as web_vital_lcp. Period comparison — compares the current period’s metric average against the preceding equivalent period (week/month/quarter).
