# One of 'breaking', 'deprecation', 'new_component', 'enhancement', 'bug_fix'
change_type: enhancement

# The name of the area of concern in the attributes-registry, (e.g. http, cloud, db)
component: k8s

# A brief description of the change. Surround your text with quotes ("") if it needs to start with a backtick (`).
note: Add `k8s.pod.cpu.time`, `k8s.pod.cpu.usage`, `k8s.node.cpu.time`, `k8s.node.cpu.usage` metrics

# Mandatory: One or more tracking issues related to the change. You can use the PR number here if no issue exists.
# The values here must be integers.
issues: []

# (Optional) One or more lines of additional information to render under the primary note.
# These lines will be padded with 2 spaces and then inserted directly into the document.
# Use pipe (|) for multiline entries.

# Semantic Conventions for K8s Metrics

**Status**: [Experimental][DocumentStatus]

## K8s Metrics

This document describes instruments and attributes for common K8s level
metrics in OpenTelemetry. These metrics are collected from technology-specific,
well-defined APIs (e.g. Kubelet's API).

### Metric: `k8s.pod.cpu.time`

This metric is [recommended][MetricRecommended].

| Name | Instrument Type | Unit (UCUM) | Description | Stability |
| -------- | --------------- | ----------- | -------------- | --------- |
| `k8s.pod.cpu.time` | Counter | `s` | Total CPU time consumed [1] | ![Experimental](https://img.shields.io/badge/-experimental-blue) |


**[1]:** Total CPU time consumed by the specific Pod on all available CPU cores

| Name | Instrument Type | Unit (UCUM) | Description | Stability |
| -------- | --------------- | ----------- | -------------- | --------- |
| `k8s.pod.cpu.usage` | Gauge | `{cpu}` | Pod's CPU usage, measured in cpus. Range from 0 to the number of allocatable CPUs [1] | ![Experimental](https://img.shields.io/badge/-experimental-blue) |


**[1]:** CPU usage of the specific Pod on all available CPU cores, averaged over the sample window
