NodePing Elixir v1.1.4 NodePing.Checktypes.Ntp View Source

Use the NTP check when you want to monitor the uptime of your NTP servers or to receive alerts when private servers become publically available, as in the case of a failing firewall rule. The check can be configured to send you notifications if it's able to get a response or if it's not able to get a response.
