First all thanks for the response

kernel process in question is nfsd. The number of thread 
is kept in /proc/fs/nfsd/threads. 

So the idea would be doing a systemctl status nfsd 
and number in /proc/fs/nfsd/threads is zero the
service would be deactive. An non-zero number the
service would active. 

Is this something systemd could be used for?
