Tells ndb_config  to print information relating only to parameters defined in an [ndbd]  or [ndbd default]  section of the cluster configuration file (see Section 23.3.3.6, “Defining NDB Cluster Data Nodes” ). 

This option is mutually exclusive with --connections  and --system ; only one of these 3 options can be used. 

• --query= query-options , -q query-options 

<img src='content_image/691169.jpg'>

This is a comma-delimited list of query options —that is, a list of one or more node attributes to be returned. These include nodeid  (node ID), type (node type—that is, ndbd , mysqld , or ndb_mgmd ), and any configuration parameters whose values are to be obtained. 

For example, --query=nodeid,type,datamemory,datadir  returns the node ID, node type, DataMemory , and DataDir  for each node.

If a given parameter is not applicable to a certain type of node, than an empty string is returned for the corresponding value. See the examples later in this section for more information.
