box.info()

box.info()¶

Get all keys and values provided by the box.info submodule. Since box.info contents are dynamic, it’s not possible to iterate over keys with the Lua pairs() function. For this purpose, box.info() builds and returns a Lua table with all keys and values provided in the submodule.

Return:	keys and values in the submodule
Rtype:	table

Example

This example is for a master-replica set that contains one master instance and one replica instance. The request was issued at the replica instance.
