Checkmk Werk 7482: mk_mysql: More consistent naming of instances

ID: 7482 Title: mk_mysql: More consistent naming of instances Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 The naming of different mysql instances has been simplified. The item names of the monitored instances are now given by the corresponding sockets (e.g. an instance using the socket "/var/run/mysql.sock" will be called "/var/run/mysql.sock"). If no socket can be determined, only one instance will be monitored, using the default name "mysql". Previously as a third attempt the <tt>--user=</tt> option found in the output of <tt>ps -fww -C mysqld</tt> has been used as instance name. This is not longer considered. The determination of the sockets themselves is unchanged: If no sockets are listed in the config file, the socket is determined by the <tt>--socket=</tt> option found in <tt>ps -fww -C mysqld</tt>. If you are monitoring mysql instances that do not use the default item name "mysql", a rediscovery is required.
