Deployment and HPA metrics with Container insights

  • Article

The Container insights integrated agent automatically collects metrics for deployments and horizontal pod autoscalers (HPAs).

Deployment metrics

Container insights automatically starts monitoring deployments by collecting the following metrics at 60-second intervals and storing them in the InsightMetrics table.

Metric name Metric dimension (tags) Description
kube_deployment_status_replicas_ready container.azm.ms/clusterId, container.azm.ms/clusterName, creationTime, deployment, deploymentStrategy, k8sNamespace, spec_replicas, status_replicas_available, status_replicas_updated (status.updatedReplicas) Total number of ready pods targeted by this deployment (status.readyReplicas). The dimensions of this metric are:
  • deployment - name of the deployment
  • k8sNamespace - Kubernetes namespace for the deployment
  • deploymentStrategy - Deployment strategy to use to replace pods with new ones (spec.strategy.type)
  • creationTime - deployment creation timestamp
  • spec_replicas - Number of desired pods (spec.replicas)
  • status_replicas_available - Total number of available pods (ready for at least minReadySeconds) targeted by this deployment (status.availableReplicas)
  • status_replicas_updated - Total number of non-terminated pods targeted by this deployment that have the desired template spec (status.updatedReplicas)

HPA metrics

Container insights automatically starts monitoring HPAs by collecting the following metrics at 60-second intervals and storing them in the InsightMetrics table.

Metric name Metric dimension (tags) Description
kube_hpa_status_current_replicas container.azm.ms/clusterId, container.azm.ms/clusterName, creationTime, hpa, k8sNamespace, lastScaleTime, spec_max_replicas, spec_min_replicas, status_desired_replicas, targetKind, targetName Current number of replicas of pods managed by this autoscaler (status.currentReplicas). The dimensions of this metric are:
  • hpa - name of the HPA
  • k8sNamespace - Kubernetes namespace for the HPA
  • lastScaleTime - Last time the HPA scaled the number of pods (status.lastScaleTime)
  • creationTime - HPA creation timestamp
  • spec_max_replicas - Upper limit for the number of pods that can be set by the autoscaler (spec.maxReplicas)
  • spec_min_replicas - Lower limit for the number of replicas to which the autoscaler can scale down (spec.minReplicas)
  • status_desired_replicas - Desired number of replicas of pods managed by this autoscaler (status.desiredReplicas)
  • targetKind - Kind of the HPA's target (spec.scaleTargetRef.kind)
  • targetName - Name of the HPA's target (spec.scaleTargetRef.name)

Deployment and HPA charts

Container insights includes preconfigured charts for the metrics listed earlier in the table as a workbook for every cluster. You can find the deployments and HPA workbook Deployments & HPA directly from an Azure Kubernetes Service cluster. On the left pane, select Workbooks and select View Workbooks from the dropdown list in the insight.
