Benjamin Mahler closed MESOS-38.
--------------------------------
Resolution: Duplicate
I'll be opening a new ticket for this to reflect the current state of the
world, and to be more accurate as to what I'm currently implementing.
> Executor resource monitoring and local reporting of usage stats
> ---------------------------------------------------------------
>
> Key: MESOS-38
> URL: https://issues.apache.org/jira/browse/MESOS-38
> Project: Mesos
> Issue Type: New Feature
> Components: isolation, slave
> Environment: Initial executor monitoring for linux only. Dummy
> monitoring capability (no-op) for OSX, with functionality to be filled in
> later.
> Reporter: Sam Whitlock
> Assignee: Benjamin Mahler
> Labels: monitoring
>
> Implement reporting of resource usage on executors and log them to a local
> log file (for now). The eventual usage of this will be to report these
> statistics to the Mesos master in order to build either or both a timeline
> for the webui and/or a top-like command-line interface. This improvement
> ticket is just for the local monitoring and log file reporting. A reporting
> system (to the master node) will be a later improvement ticket.
> With the current version of Mesos, it is not possible to monitor individual
> tasks. Therefore the best this sort of system can do is monitor the usage of
> an individual executor and aggregate the resource usage of over the
> executor's tasks and resource allocations. If frameworks have a 1-to-1
> relationship of a job to an executor, then the aggregate statistics will be
> more meaningful.
> Reporting will be available for both lxc isolation and process-based
> isolation. For lxc isolation the task is easier because of the isolation
> facilities of lxc. Process-based isolation is more difficult as processes can
> become re-parented from the process tree of the executor (e.g. double fork).
> The session ID and the process group ID will likely still be the same as that
> of the executor except for the uncommon case of the process resetting both of
> those.
> When usage statistics are eventually reported to the Mesos master, it may be
> possible to use them to oversubscribe slave nodes.
