Kubernetes Container

This page describes the Optimization Pack for the Kubernetes Container component type.

Metrics

CPU

Name	Unit	Description
container_cpu_used	millicores	The CPUs used by the container
container_cpu_throttle_time	percent	The amount of time the CPU has been throttled
container_cpu_request	millicores	The CPUs requested for the container
container_cpu_throttled_millicores	millicores	The CPUs throttling per container in millicores
container_cpu_limit	millicores	The CPUs allowed for the container
container_cpu_util	percent	The percentage of CPUs used with respect to the limit

Memory

Name	Unit	Description
container_memory_util	percent	The percentage of memory used with respect to the limit. Memory used includes all types of memory, including file system cache
container_memory_util_nocache	percent	The percentage of working set memory used with respect to the limit
container_memory_used	bytes	The total amount of memory used by the container. Memory used includes all types of memory, including file system cache
container_memory_request	bytes	The memory requested for the container
container_memory_limit	bytes	The memory limit for the container
container_memory_working_set	bytes	The current working set in bytes
container_memory_limit_hits	hits/s	The number of times per second the used memory hit the limit
container_memory_limit_util	percent	Percent memory limit per container relative to total physical memory of the host.
container_host_memory_total	bytes	Total physical memory on the host.

memory_limit	integer	megabytes	You should select your own default value.	You should select your own domain.	yes	Limits on the amount of memory resources usage in megabytes

Constraints

The following tables show a list of constraints that may be required in the definition of the study, depending on the tuned parameters:

Formula	Notes
