Monitors

Monitors are the core of Ninja Uptime.

Each monitor represents a URL or endpoint that is continuously checked for availability and performance.

Monitors List​

The Monitors page displays all configured monitors in a table view.

Columns​

  • Domain — The monitored URL or endpoint
  • Status — Current health of the monitor
  • Last Check — Timestamp of the most recent check (UTC)
  • Enabled — Whether monitoring is active
  • Actions — Edit or delete the monitor

Status Indicators​

Monitors display a visual status:

  • 🟢 Up — Responding as expected
  • 🔴 Down — Failed checks
  • ⚠️ Warning — Configuration or alert issues

Warnings​

You may see warning messages such as:

“Monitor doesn't have an alert policy set”

This means:

  • The monitor is active
  • But no alerts will be sent if it fails

👉 It is recommended to assign an alert policy to every monitor.
