Message Audit Policy questions/ Log file viewing

I have enabled Message Audit Policy. If I go to /opt/openfire/logs/, I don’t see any log for this date. I assume I have to restart Openfire.

So, once I start producing logs, how do I read them. Do folks just use an application that parses XML? I have read some about applications that have been developed for log viewing, but they seemed rather dated, like 2005-2006.

What are administrator’s using to view log files?
