Core concepts

A probe is a single configured check — for example a DNS lookup, an HTTP request, a TCP connection test, or a TLS certificate inspection.

A run is one execution of a probe from one or more regions.

A region is a cloud provider region where a RegionCheck worker executes the probe. See Regions & providers for the full list.

A result is the structured output of a run from a specific region. See Understanding results for a field-by-field breakdown.

A scheduled check is a saved probe that runs on a schedule, so you get ongoing monitoring instead of a one-off result. See Saved & scheduled checks.

An incident is a detected failure or degradation from a scheduled check. See Incidents & alerting for how incidents are detected and how alerts are sent.

A workspace is your container for saved checks, scheduled checks, API keys, and billing.
