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：

        },
        "reserved_resources": {},
        "unreserved_resources": {

        },
        "attributes": {},
        "active": true,
        "version": "0.27.1",
        "TASK_STAGING": 0,
        "TASK_STARTING": 0,
        "TASK_RUNNING": 7,
        "TASK_FINISHED": 18,
        "TASK_KILLED": 27,
        "TASK_FAILED": 3,
        "TASK_LOST": 0,
        "TASK_ERROR": 0,
        "framework_ids": ["bd9c29d7-8530-4c5b-8c50-5d2f60dffbf6-0000", "bd9c29d7-8530-4c5b-8c50-5d2f60dffbf6-0002"]
    },
    ...
}

您可以迭代所有从属对象，并通过汇总 resources 然后减去 used_resources .
