Comment (by anarcat):

 so just to formalize this, here are the questions we should answer first
 here:

  1. what is the purpose of setting up a log host? I can imagine a few
 reasons myself, but would prefer if that was stated in the request
  2. do we use syslog or something else that's more searchable? (ELK, Loki,
 etc)
  3. do we still log on the individual hosts? or do we '''forward''' all
 the logs on the central server and keep nothing locally? (because that
 could break stuff like the postfix exporter)
  4. what about non-syslog logs? should those be centralized as well?
  5. which hardware?

 I'd be down for setting up something like this and, in the infrared
 working groups, there's been talk of looking at this problem specifically.
 I know a fellow sysadmin has been experimenting with "log forwarding" that
 is, a simple syslogd running on a central server, and all other syslogd
 '''forward''' their logs to the server, and write nothing locally. They
 are worried about disks being overloaded with I/O and things relying on
 logs on the remote servers being present, but so far things go well.
