Introduction

CExpert (Connection Expert) is a simple library that allow high-availability projects to check their mysql/mssql base's health

Details

It consists of two parts a daemon and a client library. The CExpert daemon is a light process that periodically checks MySQL/MSSQL's health and reports it to all clients interested. Communication between processes is implemented using POSIX shared memory, so reading health status is simply a matter of checking one memory byte.
