K8sメトリクス
この文書では、OpenTelemetryにおける一般的なK8sレベルのメトリクスのInstrumentと属性について説明します。これらのメトリクスは、技術固有の明確に定義されたAPI（KubeletのAPIなど）から収集されます。
k8s.名前空間のInstrumentによるメトリクスは、K8s Resourceに関連付けるべきであり（SHOULD）、それによってk8s.pod.nameやk8s.pod.uidなどのその属性を引き継ぎます。

It is best to not depend too much on the exact value but rather look at it as either == 0, in which case you can conclude there were no restarts in the recent past, or > 0, in which case you can conclude there were restarts in the recent past, and not try and analyze the value beyond that.

| Name | Instrument Type | Unit (UCUM) | Description | Stability | Entity Associations |
|---|---|---|---|---|---|
k8s.service.endpoint.count | Gauge | {endpoint} | Number of endpoints for a service by condition and address type. [1] | | k8s.service |
[1]: This metric is derived from the Kubernetes EndpointSlice API. It reports the number of network endpoints backing a Service, broken down by their condition and address type.
In dual-stack or multi-protocol clusters, separate counts are reported for each address family (IPv4, IPv6, FQDN).
When the optional zone attribute is enabled, counts are further broken down by availability zone for zone-aware monitoring.
An endpoint may be reported under multiple conditions simultaneously (e.g., both serving and terminating during a graceful shutdown).
See K8s EndpointConditions for more details.
The conditions represent:
ready: Endpoints capable of receiving new connections.serving: Endpoints currently handling traffic.terminating: Endpoints that are being phased out but may still be handling existing connections.
For Services with publishNotReadyAddresses enabled (common for headless StatefulSets),
this metric will include endpoints that are published despite not being ready.
The k8s.service.publish_not_ready_addresses resource attribute indicates this setting.
Attributes:
| Key | Stability | Requirement Level | Value Type | Description | Example Values |
|---|---|---|---|---|---|
k8s.service.endpoint.address_type | | Required | string | The address type of the service endpoint. [1] | IPv4; IPv6 |
k8s.service.endpoint.condition | | Required | string | The condition of the service endpoint. [2] | ready; serving; terminating |
k8s.service.endpoint.zone | | Recommended | string | The zone of the service endpoint. [3] | us-east-1a; us-west-2b; zone-a; `` |
[1] k8s.service.endpoint.address_type: The network address family or type of the endpoint.
This attribute aligns with the addressType field of the
K8s EndpointSlice.
It is used to differentiate metrics when a Service is backed by multiple address types
(e.g., in dual-stack clusters).
[2] k8s.service.endpoint.condition: The current operational condition of the service endpoint.
An endpoint can have multiple conditions set at once (e.g., both serving and terminating during rollout).
This attribute aligns with the condition fields in the K8s EndpointSlice.
[3] k8s.service.endpoint.zone: The zone where the endpoint is located, typically corresponding to a failure domain.
This attribute aligns with the zone field of endpoints in the
K8s EndpointSlice.
It enables zone-aware monitoring of service endpoint distribution and supports
features like Topology Aware Routing.
If the zone is not populated (e.g., nodes without the topology.kubernetes.io/zone label),
the attribute value will be an empty string.

|---|---|---|---|---|---|
k8s.service.load_balancer.ingress.count | Gauge | {ingress} | Number of load balancer ingress points (external IPs/hostnames) assigned to the service. [1] | | k8s.service |
[1]: This metric reports the number of external ingress points (IP addresses or hostnames) assigned to a LoadBalancer Service.
It is only emitted for Services of type LoadBalancer and reflects the assignments
made by the underlying infrastructure’s load balancer controller in the
.status.loadBalancer.ingress field.
A value of 0 indicates that no ingress points have been assigned yet (e.g., during provisioning).
A value greater than 1 may occur when multiple IPs or hostnames are assigned (e.g., dual-stack configurations).
This metric signals that external endpoints have been assigned by the load balancer controller, but it does not guarantee that the load balancer is healthy.
