Hello,

I have installed ELK-5.4.0 in our environment and from an agent installation we collected metrics and we are able to see the fields names as  
ex:  
elasticsearch\_jvm.mem\_heap\_max\_in\_bytes

but now we see the fields like

e.mem\_heap\_max\_in\_bytes

can i know why suddenly object fields names got changed.....?

Thanks,
