ndb_config — Extract NDB Cluster Configuration Information Specifies the connection string to use in connecting to the management server. The format for the connection string is the same as described in Section 23.3.3.3, “NDB Cluster Connection Strings” , and defaults to  localhost:1186 . Do not read default options from any option file other than login file. Specify the node ID of the node for which configuration information is to be obtained. 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. 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. 4286 • --query-all ,  -a • --query= query-options ,  -q query-options • --nodes • --nodeid= node_id • --no-defaults Note Default Value [none] Command-Line Format --query=string Type String Default Value Command-Line Format --nodes Type Boolean Default Value FALSE Command-Line Format --ndb-nodeid=# Type Integer Default Value [none] Command-Line Format --no-defaults
