Monitoring system
The NTP Pool does a basic health check of each server in the system on a regular basis and then calculates a “score” of healthy servers to include when clients requests a server.
The system has a small API that returns servers due for a test and another API to return test results. This makes the monitor very small.
Add a monitor
If you are running an NTP Pool development system, you can add monitoring system in the ‘monitors’ table. The “pool” tool has a feature for it.
./pool addmonitor email@example.com 127.0.0.1 v4
It will return an api key to be used with the ./monitor script.
