1 - Kubernetes Component SLI Metrics

FEATURE STATE: Kubernetes v1.26 [alpha]

As an alpha feature, Kubernetes lets you configure Service Level Indicator (SLI) metrics for each Kubernetes component binary. This metric endpoint is exposed on the serving HTTPS port of each component, at the path /metrics/slis. You must enable the ComponentSLIs feature gate for every component from which you want to scrape SLI metrics.

SLI Metrics

With SLI metrics enabled, each Kubernetes component exposes two metrics, labeled per healthcheck:

  • a gauge (which represents the current state of the healthcheck)
  • a counter (which records the cumulative counts observed for each healthcheck state)

You can use the metric information to calculate per-component availability statistics. For example, the API server checks the health of etcd. You can work out and report how available or unavailable etcd has been - as reported by its client, the API server.

The prometheus gauge data looks like this:

# HELP kubernetes_healthcheck [ALPHA] This metric records the result of a single healthcheck.
# TYPE kubernetes_healthcheck gauge
kubernetes_healthcheck{name="autoregister-completion",type="healthz"} 1
kubernetes_healthcheck{name="autoregister-completion",type="readyz"} 1
kubernetes_healthcheck{name="etcd",type="healthz"} 1
kubernetes_healthcheck{name="etcd",type="readyz"} 1
kubernetes_healthcheck{name="etcd-readiness",type="readyz"} 1
kubernetes_healthcheck{name="informer-sync",type="readyz"} 1
kubernetes_healthcheck{name="log",type="healthz"} 1
kubernetes_healthcheck{name="log",type="readyz"} 1
kubernetes_healthcheck{name="ping",type="healthz"} 1
kubernetes_healthcheck{name="ping",type="readyz"} 1

While the counter data looks like this:

# HELP kubernetes_healthchecks_total [ALPHA] This metric records the results of all healthcheck.
# TYPE kubernetes_healthchecks_total counter
kubernetes_healthchecks_total{name="autoregister-completion",status="error",type="readyz"} 1
kubernetes_healthchecks_total{name="autoregister-completion",status="success",type="healthz"} 15
kubernetes_healthchecks_total{name="autoregister-completion",status="success",type="readyz"} 14
kubernetes_healthchecks_total{name="etcd",status="success",type="healthz"} 15
kubernetes_healthchecks_total{name="etcd",status="success",type="readyz"} 15
kubernetes_healthchecks_total{name="etcd-readiness",status="success",type="readyz"} 15
kubernetes_healthchecks_total{name="informer-sync",status="error",type="readyz"} 1
kubernetes_healthchecks_total{name="informer-sync",status="success",type="readyz"} 14
kubernetes_healthchecks_total{name="log",status="success",type="healthz"} 15
kubernetes_healthchecks_total{name="log",status="success",type="readyz"} 15
kubernetes_healthchecks_total{name="ping",status="success",type="healthz"} 15
kubernetes_healthchecks_total{name="ping",status="success",type="readyz"} 15

Using this data

The component SLIs metrics endpoint is intended to be scraped at a high frequency. Scraping at a high frequency means that you end up with greater granularity of the gauge's signal, which can be then used to calculate SLOs. The /metrics/slis endpoint provides the raw data necessary to calculate an availability SLO for the respective Kubernetes component.

2 - Node metrics data

Mechanisms for accessing metrics at node, volume, pod and container level, as seen by the kubelet.

The kubelet gathers metric statistics at the node, volume, pod and container level, and emits this information in the Summary API.

You can send a proxied request to the stats summary API via the Kubernetes API server.

Here is an example of a Summary API request for a node named minikube:

kubectl get --raw "/api/v1/nodes/minikube/proxy/stats/summary"

Here is the same API call using curl:

# You need to run "kubectl proxy" first
# Change 8080 to the port that "kubectl proxy" assigns
curl http://localhost:8080/api/v1/nodes/minikube/proxy/stats/summary

Summary metrics API source

By default, Kubernetes fetches node summary metrics data using an embedded cAdvisor that runs within the kubelet.

Summary API data via CRI

FEATURE STATE: Kubernetes v1.23 [alpha]

If you enable the PodAndContainerStatsFromCRI feature gate in your cluster, and you use a container runtime that supports statistics access via Container Runtime Interface (CRI), then the kubelet fetches Pod- and container-level metric data using CRI, and not via cAdvisor.

What's next

The task pages for Troubleshooting Clusters discuss how to use a metrics pipeline that rely on these data.
