Product tour

See how LatencySentry keeps operators ahead of the slowdown.

The public tour follows the exact flow customers use: watch the status turn, inspect the evidence, route the alert, and connect the data to the rest of your workflow.

  • Latency-first monitoring
  • Recent evidence stays attached
  • Telegram and email alerts included

StatusDegraded

Endpoint still answers, but response times are drifting upward.

Latency842 ms

Latency is treated as the early warning signal, not a footnote.

EvidenceLatest checks attached

The exact failing response stays on the monitor for review.

System status

Read one health signal across every monitor.

The status view is built for fast scanning. Operators can see whether a monitor is healthy, degraded, or down without drilling through unrelated noise.

Healthy

Clear green state with normal latency and no pending alerts.

Degraded

The endpoint still works, but operators see a slowdown trend.

Down

Hard failure with retryable evidence and a clear incident trail.

Monitor detail and evidence

Every monitor keeps the proof attached to the incident.

The detail view shows the latest status, the exact response, and the recent checks that led to the alert. That makes handoffs and audits faster because the operator does not need to reconstruct the timeline.

Alerts and workflow

Alert early, route clearly, and keep the work moving.

The workflow is intentionally small. Signal turns into action, the alert lands where operators already work, and the monitor retains the evidence that closes the loop.

1

Check moves from healthy to degraded as latency crosses your threshold.

2

Telegram and email alerts fire with the monitor, the cause, and the latest evidence.

3

Operators open the monitor detail, inspect the failed response, and hand off the fix.

Alert fan-out
  • Telegram channel receives the degraded signal.
  • Email follows with the exact monitor and timing.
  • The team opens the detail view from the alert payload.
API and integrations

Use the same monitor data in dashboards, scripts, and internal tools.

The public API is read-only and versioned, so it can back a dashboard, a Postman collection, or a small integration without inventing a second source of truth.
