Documentation

Vantield Monitor checks your websites and API endpoints on a schedule, records every result, and alerts you when something fails. These guides cover each part of the product.

Getting started
Create your first monitor and see what each setting does.
Monitoring an API endpoint
Send a POST or PUT with a request body and check the response.
Alerts and notifications
Alert policies, outage verification, email, PagerDuty, mute and pause.
Dependency monitoring
Stop one outage from paging you for every service that depends on it.
Data retention
How long check results and incidents are kept on each plan.

How a check works

On each interval, Vantield sends one HTTP request to your URL and records the outcome, status code, and response time. A check fails when the status code does not match the one you expect, the response takes longer than your timeout threshold, the SSL certificate is invalid (when verification is on), or the response body does not contain your match string.

When a check fails, Vantield re-checks before alerting, so a single dropped request does not page you. If the failure is confirmed, an incident opens and your alert policy decides who is notified. When the monitor recovers, the incident resolves on its own.
