Personally I don't think the server log should be spread.
The access logs need to be examined together for a cluster of servers but the server log applies more to a single machine for troubleshooting purposes.
If one did want to "clusterize" the server log I would think a strategy using something like HP Openview with SNMP or remote syslog would be the way to go.
The dqd_log module sounds interesting. I'll have to look into it some more. I found it at
