Descrizione
This is a Feature Request
What would you like to be added A document that explains what all the different container memory metrics mean and how they are interrelated.
Why is this needed Today, the following metrics exist for container memory:
container_memory_cachecontainer_memory_mapped_filecontainer_memory_max_usage_bytescontainer_memory_rsscontainer_memory_swapcontainer_memory_usage_bytescontainer_memory_working_set_bytes
I would like to see a document that explains what they are, how they are different or similar to each other, how they nest, what container="" and container="POD" mean, which metric(s) are used by the kubelet to evict, why usage_bytes and max_usage_bytes might differ, the effects of quantized sampling, etc.
Comments A visual description would be amazing here, as there are hierarchical relationships that would benefit from such a view.
