No session replay, no product analytics, no kitchen sink. Sentrinel does one job — the sharpest possible view of your backend and the apps that call it — and does it properly.
p50 / p95 / p99, throughput and Apdex per endpoint, with banded charts and drill-down modals.
Stacked error charts by status code today; fingerprinted, grouped issues with stack traces next.
Search full logs — headers and payloads included — down to a drag-selected slice of any chart.
See exactly which API clients drive traffic, errors and transfer — first-class, not an afterthought.
HTTP checks with uptime strips, plus threshold alerts on error rate, latency and downtime.
CPU and memory for the machines running your apps — captured by the same plugin, no extra agent.
Most APM tools tell you your API is slow. Sentrinel tells you it's slow because one consumer is hammering one endpoint. Every request is attributed to the API client behind it.
Traffic, error and data-transfer breakdowns per consumer — the view Datadog and Sentry treat as an afterthought is first-class here.
Send us millions of requests a day — Sentrinel absorbs them all, keeps your dashboards answering in milliseconds, and cleans up old data automatically. You never manage storage, servers or retention jobs.
Smart sampling keeps your bill flat: routine traffic is sampled, but every error and every slow request is kept — and your metrics stay exact. Team workspaces, per-app keys and usage quotas are built in from day one.
Keys, environments and sampling are configured from the dashboard once your app connects. Nothing else to deploy.
