MonitorsA monitor issues health checks at regular intervals to evaluate the health of an . When a pool , your load balancer takes that pool out of the server rotation.
Health checks that result in a status change for an origin server are recorded as events in the Load Balancing event logs.
Health check regions
For each option selected in a pool’s Health Check Regions, Cloudflare sends health checks from three separate data centers in that region.
If the majority of data centers for that region pass the health checks, that region is considered healthy. If the majority of regions is healthy, then the origin itself will be considered healthy.
Increased origin strain
The same problem can occur when setting low values for a monitor’s Interval.
Host header prioritization
The Cloudflare API supports the following commands for monitors. Examples are given for user-level endpoint but apply to the account-level endpoint as well.
