samba-tool drs showrepl --summary for a quick local check

Browse Source 
The default output ("classic") gives you a lot of very uninteresting
detail when everything is fine. --summary shuts up about things that
are fine but shouts a little bit when things are broken. It doesn't
provide any new information, just tries to present it in a more useful
format.
