%{summary}

cAdvisor (Container Advisor) provides container users an understanding of the
resource usage and performance characteristics of their running containers.
It is a running daemon that collects, aggregates, processes, and exports
information about running containers. Specifically, for each container it keeps
resource isolation parameters, historical resource usage, histograms of
complete historical resource usage and network statistics. This data is
exported by container and machine-wide.

cAdvisor currently supports lmctfy containers as well as Docker containers
(those that use the default libcontainer execdriver). Other container backends
can also be added. cAdvisor's container abstraction is based on lmctfy's
so containers are inherently nested hierarchically.

### FIXME
### Upstream uses this invocation of go build but it fails with the following:
# go build --ldflags '-extldflags "-static"' github.com/google/cadvisor
#   # github.com/google/cadvisor
#   /usr/bin/ld: cannot find -lpthread
#   /usr/bin/ld: cannot find -lc
#   collect2: error: ld returned 1 exit status
#   /usr/lib/golang/pkg/tool/linux_amd64/6l: running gcc failed: unsuccessful exit status 0x100
#
# It *seems* fine without it, but I assume upstream has a reason for doing
# this, however I've yet to get a response on why and if it's necessary.
