Subject [jira] [Created] (MESOS-91) Monitor resources for processes by using proc
Date Thu, 17 Nov 2011 02:43:52 GMT
Monitor resources for processes by using proc

                 Key: MESOS-91
             Project: Mesos
          Issue Type: Sub-task
          Components: slave
         Environment: This is specific to Linux, as OS X does not have a proc filesystem.
            Reporter: Alex Degtiar
            Assignee: Alex Degtiar

This is primarily a component of MESOS-38

Create a ResourceMonitor implementation that monitors the memory and CPU usage of a root process
and all sub-processes of that process. This will use the Linux procfs filesystem to retrieve
processes in the relevant process tree, query each process for memory and CPU usage, and aggregate
usage into a single report. It will use the proc_utils additions of MESOS-89
for some of this functionality.

This monitor module will be used by the ProcessBasedIsolationModule to periodically measure
the memory and delta CPU usage of the slave's executors.
