Label customizations

Explore advanced label configuration

PerfectScale can recognize some labels automatically. However, it can be set up manually for advanced label configuration. This is particularly helpful when you are using custom labels to organize your K8s resources.

You can customize your labels for the workloads as well as for nodes. Currently, there are available the following options:

Label
Description

workload_labels

Defines labels that can be applied to Kubernetes resources (pods, deployments, or stateful sets) to identify and manage workloads within a cluster.

spot_labels

Identifies spot nodes.

node_group_labels

Identifies the nodes group in a cluster.

architecture_labels

Specifies the architecture of the node (x86_64, arm64, etc.)

os_labels

Specifies the operating system running on a node within the Kubernetes cluster.

instance_type_labels

Specifies the type or configuration of VMs (instances) within a cloud infrastructure.

region_labels

Specifies the geographical region where a particular resource is located.

availability_zone_labels

Specify the availability zone where a particular resource is located.

ignored_pod_labels

Defines labels that Kubernetes components should disregard when making pod decisions.

ignored_node_labels

Defines labels that Kubernetes components should disregard when making node decisions.

Label Formatting

Kube-state-metrics exposes labels following Prometheus conventions:

  1. Add the label_ prefix to the label

  2. Replace non-alphabetic characters with underscores

  3. Convert camel case to snake case by using underscores to separate words

Example

kubernetes.azure.com/scalesetpriority: spot -> label_kubernetes_azure_com_scalesetpriority: spot

node:
  spot_labels:
    label_kubernetes_azure_com_scalesetpriority: spot

🛠️ How to create Customization Profile

Customization profile from overview

Use Set as default checkbox to automatically assign the profile to the clusters. 💡 NOTE: The manually assigned profile takes priority over the default one.

🛠️ How to apply Customization Profile

Apply to a single cluster

To apply Customization Profile to the cluster, go to the Overview tab on the left panel -> find the cluster to which you want to apply the Customization Profile and click gear button -> go to Customizations -> select the needed profile in the Customization Profile drop-down list.
