API monitoring agent that watches your endpoints, tracks uptime, and triggers incident workflows when latency thresholds breach.
Sentinel continuously monitors your API endpoints with sub-second granularity. It tracks response times, status codes, payload sizes, and error rates across every endpoint in your stack. When anomalies are detected — latency spikes, 5xx surges, unexpected payload changes — Sentinel triggers your incident workflow: PagerDuty, Slack, custom webhooks. It learns your baseline traffic patterns and adapts thresholds automatically, reducing false positives by 73% compared to static alerting. Supports REST, GraphQL, gRPC, and WebSocket endpoints. Deploys as a sidecar or standalone agent.
