Too many management consoles in NoSQL/NewSQL DBMS industry!

The database industry used to be more monolothic.  Now many enteprises have a hodge-podge of pieces to their data pipeline.  Why is it that each company is coming out with their own management console front-end.  We've had recently, Cloudera, Greenplum, MongoDB, Cassandra all show off their snazzy new management consoles.  Only MarkLogic seems to have taken the integrate instead of build route (OpenView + Nagios I think.)

If there are 6-8 things touching the data in a pipeline, shouldn't they be reporting up to a central console?  Do we really need another central console technology?  Look to the networking industry for guidance here....

Next up, layer cakes of file systems and social networking portols - everyone seems to want their own one of those too....
