Hi, I almost finished the PR of collecting CPU Usage (I'm waiting for the Travis CI build...) https://github.com/apache/dubbo/pull/4195
I'm not sure if is ok dubbo-cluster including dubbo-monitor has a dependency and if some files (such as CpuUsageServiceImpl) should be in dubbo-cluster or dubbo-monitor module. I appreciate your feedback! Thanks -- Daniela Morais Computer Science student at the University Of Campinas danielammorais.com <https://www.danielammorais.com>
