Is there any APIs for HA to check synchronization status?

Is there any APIs for HA to check operational CDB or configuration CDB synchronization
Such as

  1. synchronization is on going or not?
  2. synchronization results? successful or failure or error
  3. synchronization statistics? how many bytes data are synchronized? speed? how many packets? …

The ConfD User guide mentions (24.5) contains description of HA API. There is int confd_ha_get_status function, but it does not contain metrics you mention in your post. I do not know, if there is some other API for it.
