Const ExperimentalAvailable memory for use. This is defined as the memory limit - workingSetBytes. If memory limit is undefined, the available bytes is omitted.
In general, this metric can be derived from cadvisor and by subtracting the container_memory_working_set_bytes metric from the container_spec_memory_limit_bytes metric.
In K8s, this metric is derived from the MemoryStats.AvailableBytes field of the PodStats.Memory of the Kubelet's stats API.
This metric is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
Container memory available.
