Latency Dashboard Readiness Tracker
Updated September 15, 2025
SLA & Alert Objectives
- • High-priority APIs: < 500ms response target
 - • Global SLA: 1-second ceiling
 - • Real-time alerting for spikes and degradation
 - • Dual-cluster coverage to ensure failover readiness
 
Instrumentation Actions
- Prioritize Transaction History API and other critical endpoints.
 - Instrument emitters for accurate latency telemetry.
 - Aggregate metrics into ODS for unified visibility.
 - Build visuals highlighting SLA breaches and spikes.
 - Resolve two remaining TH API fields (card number & date) with SOR team.
 - Load test both clusters with JMeter and validate logging.
 - Launch and monitor post-remediation.
 
Blockers & Follow-ups
- • Transaction History API publishing failures (Sep 25 – Oct 1).
 - • Coordinate Vince API transition post new-cluster readiness.
 - • Align QA schedule for old/new clusters before release.
 
Cross-Team Signals
- • Feed latency analytics back into the Data Consistency dashboard to contextualize SLA breaches with data quality.
 - • Share validation insights with Ontario capacity planning to right-size infrastructure.
 - • Document success criteria in Ankita's epic for executive visibility.
