哪个http端点将帮助我找到当前资源利用率的所有活动框架？我们需要这些信息是因为我们想要动态缩放Mesos簇，我们的算法需要关于每个活动框架正在使用什么资源的信息。

我认为关注框架并不是你真正想要的。你要找的可能是mesos slave利用率，这可以通过调用请求
http://{mesos-master}:5050/master/state-summary
在json答案中，您将发现 slaves 包含从属对象数组的属性：

您可以迭代所有从属对象，并通过汇总 resources 然后减去 used_resources .看见http://mesos.apache.org/documentation/latest/endpoints/master/state-summary/http://mesos.apache.org/documentation/latest/endpoints/
