On-demand checks and URL probes

Run a check immediately instead of waiting for the next interval, or test a URL before you commit to a monitor.

Two things let you get an answer now rather than at the next interval.

Check now

Runs an existing monitor immediately, using its full configuration — same regions, same assertions, same timeout. The result is recorded as a normal heartbeat and can change the monitor’s status.

In the dashboard this is the Check now button on the monitor. Over the API:

POST /monitors/<monitor-id>/check

Use it after deploying a fix, when you do not want to wait out a 30-minute interval to confirm recovery.

Probe a URL

Tests a URL without creating a monitor:

POST /monitors/probe

This is the fastest way to answer “would a monitor on this URL work?” before you commit to one — checking that a health endpoint returns what you think it does, or that a URL is reachable from Glowo’s network at all.

Because there is no monitor, a probe records no heartbeat, affects no uptime, and triggers no alerts.
