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.

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 high5 0 0 0 33554432 262144 06 0 0 0 33554432 262144 07 0 0 0 33554432 262144 08 0 0 0 33554432 262144 0== logspaces ==node_id log_type log_id log_part total used high5 0 0 0 268435456 0 05 0 0 1 268435456 0 05 0 0 2 268435456 0 05 0 0 3 268435456 0 06 0 0 0 268435456 0 06 0 0 1 268435456 0 06 0 0 2 268435456 0 06 0 0 3 268435456 0 07 0 0 0 268435456 0 07 0 0 1 268435456 0 07 0 0 2 268435456 0 07 0 0 3 268435456 0 08 0 0 0 268435456 0 08 0 0 1 268435456 0 08 0 0 2 268435456 0 08 0 0 3 268435456 0 0shell>
