. change the default nagios::service::mysql check to use the check_mysql_health 'connection-time' check mode, which is identical to the original check, with some additional information
. stop using nagios::plugin::deploy because this doesn't work when more than one node attempts to realize this class
. stop exporting the nagios_command because this doesn't work when more than one node attempts to realize this class
. remove the check_health define, instead this be how it was before, as the previous nagios::service::mysql define
* create a mysql::server::nagios::base class with the common parts needed for the basic plugin, and the health plugin
* make mysql::server:nagios inherit mysql::server:nagios::base
* create a new class mysql::server::nagios::check_health inheriting ::base
the nagios module has also received a new define to setup the different nagios::service pieces for the different health check modes that might be desired
its assumed you would setup the different health check modes in site-mysql/init.pp as different hosts will require different modes and/or parameters, for example:
class site-mysql::server {
include mysql::server::nagios::check_health
nagios::service::mysql_health { [ 'connection-time', 'uptime', 'threads-connected', 'threadcache-hitrate' ]:
require => Mysql_grant[$nagios_mysql_user],
}
case $hostname {
"eider": {
nagios::service::mysql_health { [ 'slave-io-running', 'slave-sql-running', 'slave-lag' ]:
require => Mysql_grant[$nagios_mysql_user],
}
}
}
}
