An Alert Rule has several Alert Types that specify what conditions generate alerts. When a OneVue Sync Transmitter enters an Alarm state, an alert is automatically activated and alert notifications are sent.
Alert types can be enabled or disabled and are commonly enabled based on the condition or device being monitored. By default, an Alert Rule has all alert types enabled, which OneVue only generates an alert for a condition or device being monitored.
The section below defines the alert types based on the OneVue solution and its devices.
Unique to the OneVue Notify with Critical Notifications system, only Transmitters are monitored and managed from OneVue. 72MHz Analog Clocks, Digital Clocks, and Digital Timers are not managed or monitored from OneVue and are standalone devices that receive time from the system Transmitters.
Alert is activated when a Transmitter has not checked-in to OneVue within the time period set in its Unresponsive Timeout setting. This condition is due to the device could not connect to its assigned network and failed to check-in to OneVue.
During this condition, the Transmitter is an Alarm state with an Unresponsive status.
Time Sync Failure
Alert is activated when a Transmitter reported at its last check-in that it failed to receive time from its time source. The Transmitter may not have the correct time (drift), which will impact the accuracy of secondary synchronized time devices and scheduled events.
During this condition, the Transmitter is an Alarm state with a Time Sync Failure status.
Alert is activated when a Transmitter reported at its last check-in any of the below hardware error statuses.
Bad Output Power: Transmitter is not transmitting at the appropriate power level.
PLL Diagnostics: Transmitter having trouble locking onto a channel and cannot broadcast time or events.
VSWR Errors: Transmitter antenna error from either the antenna position or cabling.
No GPS in 48 Hours: Transmitter has not received time from its time source for more than 48 hours.
No PPS in 48 Hours: Transmitter time has not been synchronized by 1PPS (1 pulse per second) for more than 48 hours.
GPS Cable Break: Transmitter has detected an error with the GPS connection; either due to a line break, water ingress, or the cable length is greater than 200 ft. (60.9 m).
Alert is activated when the Transmitter has never received time from its time source either during first-time configuration or after a power failure. During this condition the Transmitter does not transmit (broadcast) time to devices and only will only transmit critical notification events. It's important to resolve this error immediately.
