Jojy Varghese updated MESOS-2961:
---------------------------------
Description:
Current cgroups implementation does not have a cpuacct subsystem
implementation. This subsystem reports important metrics like user and system
CPU ticks spent by a process. "cgroups" namespace has subsystem specific
utilities for "cpu", "memory" etc. It could use other subsystems specific utils
(eg. cpuacct).
In the future, we could also view cgroups as a mesos-subsystem with features
like event notifications.
Although refactoring cgroups would be a different epic, listing the possible
tasks:
- Have hierarchies, subsystems abstracted to represent the domain
- Create "cgroups service"
- "cgroups service" listen to update events from the OS on files like stats.
This would be an interrupt based system(maybe use linux fsnotify)
- "cgroups service" services events to mesos (containers for example).
