Hi,
Does “tailf:suppress-echo” work on a leaf defined as list key ?
We added “tailf:suppress-echo true” to a leaf which is defined as a key to a list and found that the characters are echoed and also not masked with “\*\*\*” in audit.log.
Please confirm the behavior of this YANG extension on key leaf.
Thanks.

This annotation appears not to work for leafs that are keys, most likely since suppressing the key value would make it difficult to determine which list entry was appearing in the audit log.
Since the CLI is only supported for lab use in ConfD Basic and not in a production environment, if you are using ConfD Premium, you should open a ticket with Tail-f support to confirm this.
Thanks!
