cbdd96a554 Add task load stats to containers. 
The stats are only populated when cAdvisor is running outside network namespaces.
We'll add a different backend to retrieve the same data from within namespaces.

e44dca68b3 Memory stats should not be omited if empty. 
They may be zero. Also removed Limit from MemoryStats, that belongs in
MemorySpec and is there today. All info requests return the spec.

f97e57df88 Simplify how the Docker containers are handled. 
This is done by introducting the concept of "namespaces" of container
names. The aliases of a container are under this namespace. Namespace
names are of the form:

//<namespace>/<alias>

This allows us to (within cAdvisor) query all docker containers as
//docker regardless of whether this is a systemd or a non-systemd system.

This does break our ability to handle Docker aliases with the /container
endpoint. I think this is acceptable as our support there was not
consistent between system types.

e9d6289964 Added /proc/diskstats 
Read disk io information from /proc/diskstats.
This will allow the user who provides partition container hints to get partition-specific io (blkio provides io for the container, but at the disk device level).

5e8fecea6a Adding filesystem usage calculation for docker containers. This patch also includes some internal refactoring. 
'machine' api now exports a list of all existing 'ext*' filesystems along with the capacity.

b9e70f0240 Filesystem stats are now per container. As of now, fs stats are reported only for the 
root cgroup.
To make cadvisor detect all the disks, the rootfs of host needs to mounted
inside cadvisor.

4e028d7995 Make housekeeping interval dynamic, fist signal is resource usage. 
If no resources are used by the container since the last housekeeping,
we double the housekeeping interval until --max_housekeeping_interval.
If usage was detected, we drop it back to the baseline
(--housekeeping_interval).

From my tests this reduces CPU usage in CoreOS from ~8% to ~3% with no
real loss of accuracy.

Fixes #159

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

41d9275b51 Fixed network stats handling. The UI now reports network errors. 2014-07-23 22:24:43 +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.
