What is cAdvisor?

Google describes cAdvisor as follows:

"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 a container and is machine-wide."

The project started off life as an internal tool at Google for gaining an insight into containers that had been launched using their own container stack.

Note

Google's own container stack was called "Let Me Contain That For You" or lmctfy for short. The work on lmctfy has been installed as a Google port functionality over to libcontainer that is part of the Open Container Initiative. Further details on lmctfy can be found at https://github.com/google...
