Kibana for elasticsearch plugin ReST APIs request

Hi Folks,

I want use elasticsearch to expose my own rest endpoint, currently I just only know developing elasticsearch plugin to implement it. I was wondering if i have other easier ways?

If I use elasticseach plugin exposed my own rest endpoint, if i can create custom dashboards in kibana which can make Rest calls to these rest?

kibana at the moment only uses data from elasticsearch, to use data from different sources you would need to do quite a big modification.
