I am running Nagios on a very limited server (128 megabytes total RAM) and needed something a bit smaller than MySQL for performance graphing.
I have patched perfparse, bumping the version up to 0.105.7, to work with sqlite3.
Hopefully, I didn't break MySQL support in the process.
I removed the external keys and references for the sqlite3 schema. It should be possible to support them using triggers, but for now I just want something that works.
