Introduction
Vantaj is an uptime and infrastructure monitoring platform. It checks your HTTP endpoints, pings hosts, monitors ports, tracks domain expiry, and surfaces incidents — all from a single dashboard.
What Vantaj monitors
- HTTP(s) endpoints — checks your APIs, websites, and health routes for status codes and response times
- Ping (ICMP) — confirms a host is reachable at the network level
- Ports — verifies that a specific TCP port is open and accepting connections
- Domains — tracks expiry dates, registrar info, nameservers, and DNSSEC status so you never get caught by a lapsed registration
- Heartbeats — monitors scheduled jobs and background workers by expecting a regular ping from your code; silence triggers an alert
How it works
Vantaj runs checks from multiple regions on a configurable interval (from 30 seconds up to once a day). Each check records the status, response time, and any error. Results are stored in your account and shown in real-time on your dashboard.
When a monitor changes status — for example from Up to Down — an incident is opened automatically, and any alert policy attached to that monitor notifies you. When it recovers, the incident is resolved.
Key concepts
| Concept | Description |
|---|---|
| Monitor | A single endpoint or host you want to check |
| Check | One execution of a monitor — records status + response time |
| Incident | A period during which a monitor was not up |
| Group | An optional label for organising related monitors together |
| Heartbeat | Expects your job to ping a URL on a schedule — silence means something didn't run |
| Alert policy | Decides who gets notified, through which channels, and how alerts escalate |
| Maintenance window | A planned period during which alerts are suppressed for chosen monitors |
| Workspace | The shared environment for your org's monitors, incidents, and team |
| Project | An environment-level grouping of monitors within a workspace (Production, Staging, …) |
| Team | Members of your workspace — each with an Admin or Member role |
