b63d61ca97 Use inotify to watch for new containers. 
This reduces cAdvisor CPU usage below 1% in my CoreOS system.

We also reduce global housekeeping to every 60s as a fallback in case we
miss an event.

This is possible thanks to the new libcontainer interface that allows
the use of absolute paths.

1fa48e8c39 Fix handling of cpumask for docker driver. Raw driver still reports all 
cpus. Will fix it to read cpumask for cgroup seperately.

7f96c90c72 Fix raw cgroups handler. 2014-07-22 18:58:16 +00:00
Vishnu Kannan
1edb798de5 Features: 
Added Network Stats to Container Info. It still not exposed via the HTTP UI.
Bug fixes:
1. Modified docker handler to use libcontainer.GetStats instead of quering the fs package.
2. cAdvisor will not stall if any of its core operations fail.
3. cAdvisor will safely ignore any inactive or leaked docker containers. When containers are leaked cgroup state exists but docker is not aware of them.

a187d74e5b Enable the simple raw driver. 
It doesn't yet get the spec, but it is functional enough to use.
This removed the registration of lmctfy, the code will be removed in a
future PR once raw GetSpec() is complete.

1636c3e759 Change ContainerHandlerFactories to decide what containers they support. 
This allows a ContainerHandlerFactory to register a CanHandle() function
which is called to determine whether the factory can handle a particular
container.

This commit disables being able to run cAdvisor without lmctfy. This
should be enabled again with a "no-op" global factory which I would like
to do in a separate PR.
