There are two hooks/commands that you can configure for OpenDNSSEC:

1. Configure the <DelegationSignerSubmitCommand> if you want to have a
program/script receiving the new KSK during a key rollover.

2. <NotifyCommand> optional element that will tell the Signer Engine to
call this command when the zone has been signed. Will expand the
following variables: %zone (the name of the zone that was signed) and %
zonefile (the filename of the signed zone).

These are located in the conf.xml, see:
https://wiki.opendnssec.org/display/DOCS/conf.xml

There is no good mechanism for getting that information currently.

To understand what the big picture is could you explain why you want
this information as it happens?

There are a few different keys and states, there are HSM keys (raw key
material) and keys in KASP and they both carry a lot of states.

If time permits, sure. But right now I think we need to understand
deeper what/why you want to do this.

And if you or your team has time you could always make a pull request
with the functionality you wish to have.
