STARTUP_TIME DATE NOT NULL Time that the apply process was last started
READER_TOTAL_MESSAGES_DEQUEUED NUMBER   Total number of messages dequeued since the apply process was last started
READER_LAG NUMBER   For captured messages, the delay (in seconds) between the creation of the last message and it being received by the apply process. For user enqueued messages, the delay between the message being enqueued in the local database and being received by the apply process.

COORD_LWM_LAG NUMBER   For captured messages, the delay (in seconds) between the creation of the message corresponding to the low watermark and it being applied by the apply process. For user enqueued messages, the delay between the message being enqueued in the local database and being applied by the apply process.
SERVER_TOTAL_MESSAGES_APPLIED NUMBER   Total number of messages applied by all the apply servers since the apply process was last started
SERVER_ELAPSED_DEQUEUE_TIME NUMBER   Time elapsed (in hundredths of a second) dequeuing messages by all the apply servers since the apply process was last started
