hystrix metrics stream: The 'delay' parameter doesn't work

Question

My application integrates Hystrix as circuit breaker, and the stream endpoint is exposed at /hystrix.stream. Now I want to control the streaming frequency by 'delay' parameter:

curl "http://localhost:9000/hystrix.stream?delay=1000"

Unfortunately 'delay' doesn't work. I still receive the hystrix metrics data twice per second.

Help, thanks!

After looking up to the source code, I found that there's no way to change delay dynamically at all! Hystrix sets this parameter at the app's starting phrase.The only way to change this delay is creating a config file named config.properties in classpath, then add the following property:

hystrix.stream.dashboard.intervalInMilliseconds=2000
