Got it. Thanks Qian, haosdent – I had been looking at /monitor/statistics.json on the slave, but not state.json.

"executors": [ { "container": "b824a7ad-35c6-48ab-9378-b180ed431fb5", <----- this is <something> ... "tasks": [ { "executor_id": "", "framework_id": "83ced7f5-69b3-409b-abe5-a582a5d278cd-0000", "id": "app-docker1.f94cba69-b85e-11e5-bdf1-0242497320ff", "name": "app-docker1", ... So you can use task ID to locate the task, and each task must be under an executor, and you can get <something> from executors.container, then it can link to the Docker container name. 2016-01-12 10:44 GMT+08:00 haosdent <[email protected]<mailto:[email protected]>>: could you found it in slave state http endpoint? I remember the hierarchy should be framework->executors->container. On Tue, Jan 12, 2016 at 10:41 AM, haosdent <[email protected]<mailto:[email protected]>> wrote: <something> is containerid here.

Mesos has a task ID (like app_auth.6fb24412-af26-11e5-9900-02d62c7c9807), but the only place that shows up in the Docker container is in the MESOS_TASK_ID environment variable passed to the Docker containers. I see that the Docker containers are created using the format mesos-<slaveid>-<something>, but I cannot find the <something> value anywhere in the metadata from the master or the slave. Am I missing something, or is there any way that I can configure Mesos to add a label or something to the Docker container so that our monitoring scripts can tie the Docker container to the Mesos task?
