Analog (a) no longer seems to be maintained and (b) rebuilding the old source rpm on CentOS7 ends up with a conflict with a file named /usr/bin/analog that is owned by anaconda.
So, taking a step back: is there a better tool for apache log analysis now? One feature of analog that I haven't been able to match with anything else is that you can rsync a tree of log files from a farm of servers into one place and invoke analog with a wild-card to expand all of their names on the command line and it will digest them all without the need to pre-sort in timestamp order.
