Data Latency (ms)Long

Birth Count

Long

The number of NBIRTH messages since the last time the info metrics were reset via the Node Info/Reset Info tag


Death CountLongThe number of NDEATH messages since the last time the info metrics were reset via the Node Info/Reset Info tag


Offline DateTimeDateTimeThe time at which the last NDEATH message was received by MQTT Engine


OnlineBooleanWhether or not the Edge Node is online. This is determined by whether the last lifecycle message was an NBIRTH or NDEATH


Online DateTimeDateTimeThe time at which the first NBIRTH message for a connection was received by MQTT Engine


Rebirth CountInteger

The count of rebirth requests issued by MQTT Engine (available 4.0.22 onward)

...

Rebirth (Last DateTime)DateTimeThe time of the last rebirth request issued by MQTT Engine (available 4.0.22 onward)
