From 1bbcb8e28a3cc14513a9442b2cb630b8269a8b2b Mon Sep 17 00:00:00 2001 From: AI-Engineer Date: Sun, 31 May 2026 20:11:03 +0000 Subject: [PATCH] feat: extend monitoring to include VIN Decoder API - flux/monitoring/prometheusrule-apis.yaml: extend all 5 SLO alert rules to include vin-decoder in the job regex filter - flux/monitoring/grafana-dashboard-apis.yaml: update all PromQL expressions to include vin-decoder in the api regex filter; update dashboard description - flux/monitoring/vin-decoder-dashboard.yaml: new dedicated Grafana dashboard for VIN Decoder showing request rate by route, 5xx error rate, P50/P95/P99 latency by route, and data freshness gauge - flux/monitoring/kustomization.yaml: add vin-decoder-dashboard.yaml - flux/vin-decoder/servicemonitor.yaml: Prometheus ServiceMonitor for auto-discovery of /metrics on the vin-decoder service - flux/vin-decoder/kustomization.yaml: add servicemonitor.yaml Closes leeworks-agents/api-company#129 ---
