cAdvisor Prometheus container_cpu_load_average_10s has two values
Each metric has dimensions to it. So, it seems like the same metric, but it's only the name. What distinguishes these metrics from eachother is their labels.
If you look closely at your screenshot, you'll find these are CPU Loads of different pods of different services.
EDIT: The format that Prometheus exposes its metric is
metric_name [ "{" label_name "=" `"` label_value `"` { "," label_name "=" `"` label_value `"` } [ "," ] "}"] value [ timestamp ]This hints the last number is a timestamp.
