sql server always on dashboard - Estimate Data Loss and Estimated Recovery Time

$

Hi all,

At the always on dashboard (SSMS) there is 2 fields:

  • Estimate Data Loss (seconds) - Indicates the time difference of the last transaction log record in the primary replica and secondary replica. If the primary replica fails, all transaction log records within the time window will be lost.
  • Estimated Recovery Time (seconds) - Indicates the time in seconds it takes to redo the catch-up time. The catch-up time is the time it will take for the secondary replica to catch up with the primary replica.

These fields are always 0 and it makes no sense…

If the database replicas is not synchronizing- I’m expecting for some data loss and recovery time…

Is anyone else having this?
