container.

11462d80bc Lowering log levels. 
Reduce common logging using Kubernetes logging standards.

3e7c1b3613 Reduce the level for a few common log messages 
Following the Kubernetes convention of V(2) is normal verbosity (log
each request to a webserver).

54bc33dd2c Lowering log level for frequent events. 
Lowering all frequent normal logs to v=3. Kubelet runs by default on
debug of v=2 and we don't want to log these events in that case.

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.

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.

67af1a1bbd Add scheddebug based cpuload reader. 
Prefer netlink based reader when available as it provides stats for
processes in state other than running (sleep, diskio, uninterruptible).

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.

e3ab15417c Ignore update errors for dead containers. 
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.

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.

621bb22eeb Make dynamic housekeeping flag configurable 2014-09-16 11:04:45 -07:00
Victor Marmol
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

1a24eed18f Fix storage driver buffer duration default value. 
The cache will now hold atlest the minimum number of stats required by the UI and more
if the buffer duration is longer than the default.
