I think it would greatly help to have a SHOW ENGINE INNODB STATUS; in a machine parsable format.
Currently it requires too many regex expressions to extract info.
It should have the same info (or more) but with some strategy to easily extract data.
It can be useful for trends, comparisons, graphing over multiple outputs.
It could be any implementation, from prepending a label to each data field, to use tabular format for such info, it should keep allowing human to easily read it like it is now.
Eventually there could be an option to select the format output.
