I installed Marvel on two independent environments (DEV / PROD). I followed the same procedure on both place. On the dev side, marvel's working perfectly. However, on the prod environment, Marvel refuses to create the .marvel-es-data.
I tried to reinstall it from scratch but still the same. When listing the indexes, I get only the .marvel-es-2015.11.19.
From the web, using the /marvel/api/v1/clusters URL, it shows only empty square bracket [ ].
So the real question is why Marvel doesn't create the .marvel-es-data index ? Does anybody have any ideas ?
