Servers can have problems. When they have problems, you need to grab logs and stuff. Ever wonder what Apple developers think is important, when it comes to logs and stuff? Try serverdiagnose! serverdiagnose Then hit the Enter (return) key. Then it collects some logs into a tgz. Why a tgz? No clue. But it ends up in /tmp. Notice the name as ServerLogs- followed by the hostname, then a date stamp (yearmonthday) and an underscore followed by a timestamp. Inside the tgz is /Library/Logs, /Library/Server, /tmp/dsdiagnose (a dump of OD debug logs), serverlogs_S3vKsy (configuration statuses), a couple of things from /var/db (the most important of which is PreviousSystemLogs), and /var/log.
