Determining computer resource usage at multiple levels of a container orchestration system hierarchy

A computing device, comprising:

• a memory;
• and
• a processor device coupled to the memory to:
• identify a first container executing on a worker node of a container orchestration system comprising a plurality of worker nodes, each worker node comprising a control plane component configured to execute a container in response to a request from a scheduler;
• identify a control group (cgroup) that corresponds to the first container;
• generate a first resource utilization structure that corresponds to the first container;
• for each respective time of a plurality of successive times, obtain, by the monitor process, from the cgroup, one or more computer resource utilization values that identify real-time memory utilization of the first container at the respective time of the plurality of successive times;
• and
• store, in the first resource utilization structure, computer resource utilization information based on the one or more computer resource utilization values.

A non-transitory computer-readable storage medium that includes executable instructions configured to cause a processor device to:

• identify a first container executing on a worker node of a container orchestration system comprising a plurality of worker nodes, each worker node comprising a control plane component configured to execute a container in response to a request from a scheduler;
• identify a control group (cgroup) that corresponds to the first container;
• generate a first resource utilization structure that corresponds to the first container;
• for each respective time of a plurality of successive times, obtain, by the monitor process, from the cgroup, one or more computer resource utilization values that identify real-time memory utilization of the first container at the respective time of the plurality of successive times;
• and
• store, in the first resource utilization structure, computer resource utilization information based on the one or more computer resource utilization values.
