is there an interface in crate like there is in ES - like this one /_cluster/health?pretty=true
I know i can enable the ES one, just wondering if there was one more specific to crate.
The admin-ui that is included in Crate uses some SQL queries to determine the health. That's explained in this issue on github. Other than that there is no interface to do that. (Other than using the ES API as you mentioned)
