33216870d8 Fix usage of housekeeping_interval flag 
Defer calculation of `loadDecay`. Flags must be parsed before they can
be read, and therefore cannot be reliably be read at package init time.

4cbd91c761 Make getCgroupPath work in case of named or multi- hierarchies 
In case we have devices hierarchies mounted in named cgroup
or together with other hierarchy regexp parse will fail.
So after "devices" and before ":" can be name of cgroup or
other hierarchies names.

E.g.:
1) remount cgroups:
umount /sys/fs/cgroup/devices
mkdir /sys/fs/cgroup/named_cgroup
mount -n -t cgroup -o devices,name=named_cgroup cgroup
/sys/fs/cgroup/named_cgroup

2) add some task to nested device cgroup and check ps output
mkdir /sys/fs/cgroup/named_cgroup/test.slice
sleep 1000 &
[1] 22734
echo 22734 > /sys/fs/cgroup/named_cgroup/test.slice/tasks
ps -ao pid,cgroup | grep 22734
22734
14:devices,name=named_cgroup:/test.slice,1:name=systemd:/user.slice/user-1000.slice/session-1.scope

Rohit Jnagal
a123fd72d8 Add logic to read custom metric config files from container root. 
Docker does not provide the rootfs path through docker inspect or statefile
and the path is dependent on the storage driver being used.

Instead of enumerating the storage drivers, we pick a pid from the container
and get the config from /proc/pid/root. Although a bit expensive, this method
works for non-docker containers too.

e6de0dd8aa Add support for parsing CPU speed from /proc/cpuinfo on Power (ppc64) systems. 
/proc/cpuinfo format varies between architectures. For example

On Intel the cpu speed is shown like the following
cpu MHz		: 3000

whereas on Power systems its shown like the following
clock		: 3000MHz

This patch enables support for /proc/cpuinfo parsing on Power systems

28984d7811 Add spec to v2.0 API. 2015-02-19 17:59:41 +00:00
Rohit Jnagal
7201af3ca5 Expose a minimal 2.0 API with the first summary endpoint. 
Right now, we just do raw container name. More types to follow.
We'll re-do the older endpoint in 2.0 before we publish it.

99a48d8310 Make explicit the use of InMemoryStorage in Manager. 
The current structure is a remnant of when the in memory storage was one
of the options for backing store. Today, we always have the memory
storage with an optional "backend storage" plugin. This commit makes the
InMemoryStorage use explicit.

86238d0179 Allow partial success of GetStats(). 
This should make us more robust in the face of failure (at the cost of
making the failures less prominent). We allow GetStats() to return an
error and a partial result. We will process the result and report the
error.

Fixes #306.

Prefer netlink based reader when available as it provides stats for
processes in state other than running (sleep, diskio, uninterruptible).

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.

This adds an Exists() interface to detect when the container is dead.
Before reporting an update error we check is Exists() is true.

Some documentation was added as well.

181e12dda2 Refactoring and fixes of /docker API endpoint. 
This canges the output of the Docker endpoint to be a map so that it is
more consistent from single to multiple returns. It also refactors
internally how we handle both types of requests.

Without this PR the /docker API endpoint is broken completely so this
change in format has no effect anyways.

These changes are tested by the upcoming integration tests.
