A couple of follow-up questions ... are there any flavors of Linux that won't work with LogStash (or the ELK stack)? If we have an opportunity to put this on ZLinux, is that going to be problematic, or is it close enough to RHEL, Ubuntu, etc.? Certainly ZLinux has to be closer than AIX.
On the prior question about SSL certificates ... is there a way to just turn that off entirely when running LogStash? Just thinking about other possible workarounds.
