28dfea761c Add events StoragePolicy. 2015-05-01 10:42:17 -07:00
Victor Marmol
1c25746cf0 Limit events to 100,000 of each type. 
This gives us a bit over one event per second for one day. Assuming 250
bytes per event, the max memory usage is ~24MiB per event type.

d0424eca0f Add --docker_only flag to enable tracking for only docker containers and root. 
This reduces unnecessary load on the system and also cleans up the UI clutter.
Currently defaulted to false.

fd1ff04f7f Split OOM event into OOM and OOM Kill. 
This will allow to watch and differentiate that the OOM victim may not
equal the OOM'd container.

unmarshaling. Made into a union of concrete types.

This allows us to handle the case where there are no factories as

a0a419614f Add /storage endpoint to 2.0 API. 
/storage returns {device, mountpoint, capacity, usage} for all filesystems.
In addition, it also detect and applies label for each filesystem - currently two - "root", "docker-images".

/storage/<label> returns info about the filesystem with specific label. eg. /storage/root returns info for root filesystem.

InMemoryStorage use explicit.

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.

742bb8c724 Do not duplicate Docker container output. 
Since Docker containers are known by more than one name we were
returning them once for every name they're known by. This change makes
the returned containers unique.
 2014-11-17 10:40:28 -08:00

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.
