HTTP uptime and latency monitoring

Verify endpoint health before incidents spread.

SLA Sentinel is an early-stage monitoring workspace for HTTP endpoints. Create checks, compare expected status codes, track latency, and inspect recent failures from one dashboard.

Current scope

The current product focuses on single-workspace HTTP monitoring, recent check history, and operator-friendly failure context.

Everything you need to protect your SLA

Configure monitors in minutes and track reliability with real evidence. No noisy dashboards, just the metrics that matter.

Expected status matching

Track whether each endpoint returns the status code your monitor expects.

Recent check history

Inspect the latest health results, status codes, latency, and error messages per endpoint.

Manual verification

Queue a monitor immediately from the dashboard instead of waiting for the next worker poll.

How it works

Add a monitor, define the expected status code and timeout, then let the Sentinel worker perform checks while Convex keeps state and history in sync.

01

Add your HTTP endpoint, expected status, interval, and timeout.

02

A separate worker polls due monitors, performs HTTP requests, and batch-writes results into Convex.

03

Open the dashboard to review latest latency, plan-aware limits, failure streaks, and recent history.
