MPP - working towards version 1.0.4

I have been working on some changes to MPP to aid in using multiple cache files. Out of the box with 1.0.3, one cache file is easily managed. With 1.0.4, I am trying to make it easier to manage multiple cache files. This allows us to use the MPP tools to work with multiple cache files in single command calls.
I am also attempting to improve MPP setup and configuration.

MPP still remains a solution to create a failover scenario for MySQL servers. But I am seeing it can be good for just monitoring groups of MySQL servers participating in a replication ring.

As such, the changes I am working on now will aid us in setting up MPP environments, and monitoring MPP statistics. One tool to be released in 1.0.4 is mpp-monitor which will generate status reports and error reports, plus e-mail the reports out. mpp-monitor has been finished and is available in the MPP Subversion repository. You need only have MIME::Lite installed so it can send e-mail.

For 1.0.4, there will be no updates to MPP's integration with MySQL Proxy. I have been kind of waiting to see what the MySQL Proxy team releases next. As I discussed in the MySQL Proxy Forums, It would be great if we can either launch threads in Lua, or launch a Lua script on the startup command line into a thread, or allow the administrative port to have access to the Lua global variable environment. All these would allow MySQL Proxy to monitor MySQL out-of-bandwidth. As of right now, we monitor MySQL when actual client connections are made. This is what MPP does. It makes a client connection to Proxy and loads its statistics into the Lua global variables. If you are interested, you should read my posts in the MySQL Proxy forums.
