This is a deprecated option tells it to not write anything to disk.

Did you modify auditd.conf to have the format be nolog? If so, its an
explained condition. Nolog means no logging to disk.

For remote logging, you should set the format to enriched. This resolves
things locally so that the aggregating server can make sense of it later. If
you do not want events written to disk on the remote system, set write_logs =
no. You should also set name_format = hostname (or something else) in
auditd.conf of the remote systems. This is so you can tell who is creating the
events in the aggregating server.

On the aggregating server, also set the format to enriched. But there you have
to have write_logs = yes. Also set name_format = hostname in auditd.conf of
the server.

I would not recommend setting the name in audispd.conf for any system.
