The MyCAT project is a toolset for managing
MySQL/Linux servers, and could be helpful for
anyone managing a network of *nix servers whether
running MySQL Cluster, standard replication, or
not running MySQL at all. At present, it contains
three programs. rcall eases use and
administration of groups (clusters) of *nix
servers by creating logical groupings and a single
location from which to run commands on all servers
while entering it only once. It requires only an
SSH connection. rep_mon is a replication monitor
that notifies if a server is lagging or has
encountered any errors. It handles any replication
topology easily. binlog_mon monitors disk space
used by MySQL binary logs, purging only when disk
space is needed. It checks all slaves to ensure
that purged files are not still being read by
slaves. It has configurable behavior in the event
that a slave still needs the oldest file.
