Check_MK Werk 6484: Fixed filtering check plugins for the management board and the host itself

ID: 6484 Title: Fixed filtering check plugins for the management board and the host itself Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 In order to decide which check is used for which data source we have to filter the found check plugins. This is done via the check_info key "management_board". There are three values with the following meanings: - MGMT_ONLY These check plugins - are only used for management board data sources, - have the prefix 'mgmt_' in their name, - have the prefix 'Management Interface:' in their service description. - If there is an equivalent host check plugin then it must be 'HOST_ONLY'. - HOST_PRECEDENCE - Default value for all check plugins. - It does not have to be declared in the check_info. - Special situation for SNMP management boards: - If a host is not a SNMP host these checks are used for the SNMP management boards. - If a host is a SNMP host these checks are used for the host itself. - HOST_ONLY These check plugins - are used for 'real' host data sources, not for host management board data sources - there is an equivalent 'MGMT_ONLY'-management board check plugin. Migration from 1.4 to 1.5: in 1.4 TCP hosts with SNMP management boards discovered TCP and SNMP checks, eg. uptime and snmp_uptime. During checking phase these checks should be executed further on. In versions >= 1.5 there are management board specific check plugins, eg. mgmt_snmp_uptime. After a re-discovery Check_MK finds the uptime check plugin for the TCP host and the mgmt_snmp_uptime check for the SNMP management board. Moreover Check_MK eliminates 'HOST_ONLT' checks like snmp_uptime.
