Sorry for the delay. I've been away on vacation and jobtrips and
this sort of fell between the chairs.

I was hoping someone else would comment on this for a yea or nay
response. Since the information is already present in the command
(which does get sent to the module, if it subscribes to commands),
this would simply make it accessible in a new way. While I have no
objections to that in general, I also have no strong opinion in
favour of it.

I take it you want this for mk_livestatus for some reason? I won't
add it unless there's a usecase for it, and the potential case
where ndoutils might need it isn't strong enough for that. A used
module wanting this to make it more effective would be a strong
incentive to put it in though.

Thanks.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
