18.4.2 ndbinfo_select_all — Select From ndbinfo Tables

ndbinfo_select_all is a client program that selects all rows and columns from one or more tables in the ndbinfo database. It is included with the MySQL Cluster distribution beginning with MySQL Cluster NDB 7.2.2.

Not all ndbinfo tables can be accessed by this program. ndbinfo_select_all can access the counters, diskpagebuffer, logbuffers, logspaces, nodes, resources, threadblocks, threadstat, and transporters tables.

To select from one or more ndbinfo tables using ndbinfo_select_all, it is necessary to supply the names of the tables when invoking the program as shown here:

shell> ndbinfo_select_all table_name1  [table_name2] [...]

For example:

shell> ndbinfo_select_all logbuffers logspaces
== logbuffers ==
node_id log_type        log_id  log_part        total   used    high
