if this project is not being maintained then how would issues with this be resolved? As many would be using turbine application to have an aggregated view of hystrix circuit breaker dashboard.

Or is there any way to get the same functionality without using Turbine anymore?

@JagmohanSharma I'm also wondering this — perhaps there are other implementations?
