Hello Ian, and welcome to the thwack community!
There are numerous methods of extracting data, archiving, etc... but really, the power of Kiwi is in it's versatility and configurability, it's not just a syslog server unless that's all you use it for.
My suggestions:
1. Stop using the catch-all file as your only method of logging messages.
2. At the very least, install the express version of SQL Server 2005/2008 (make sure you also install the management console and the command line tools)
3. Create a rule to log the Cisco telepresence messages to the DB you created.
4. You might also setup some critical alerts and things like that.
5. Give your NOC team access to the DB you created and if you have a DBA anywhere in your company you should be set at a bare minimum. Having some web development experience or someone familiar with something like Crystal Reports somewhere in there could make things easier as well.
Now, if you're going to be using the express version of SQL, there are some limitations you need to be aware of. First, it has a 4GB database file limit and will stop logging any more messages to the DB at that point. Secondly you cannot schedule maintenance jobs so what you will have to do is write T-SQL Scripts to perform any maintenance and then use Windows Scheduler to schedule sqlcmd.exe to run the T-SQL Script.
Hope that helps,
Acy
