Method Detail

initialize

public void initialize()

An implementation note. If there's a version mismatch between hystrix-core and hystrix-codahale-metrics-publisher, the code below may reference a HystrixRollingNumberEvent that does not exist in hystrix-core. If this happens, a j.l.NoSuchFieldError occurs. Since this data is not being generated by hystrix-core, it's safe to count it as 0 and we should log an error to get users to update their dependency set.
