Struct DynamicLabelConfig 

pub struct DynamicLabelConfig {
    pub key: String,
    pub strategy: DynamicLabelStrategy,
}

Configuration for a dynamic label — an always-on rotating label value attached to every emitted event.

Unlike CardinalitySpikeConfig, dynamic labels are not time-windowed: they appear in every event for the lifetime of the scenario. This enables simulating a stable fleet of N distinct sources (e.g., 10 hostnames, 5 pod names) without a spike/window concept.

Example YAML (counter strategy)

dynamic_labels:
  - key: hostname
    prefix: "host-"
    cardinality: 10

Example YAML (values list strategy)

dynamic_labels:
  - key: region
    values: [us-east-1, us-west-2, eu-west-1]

Fields

key: String

The label key to attach to every event.

Must be a valid Prometheus label key: [a-zA-Z_][a-zA-Z0-9_]*.

strategy: DynamicLabelStrategy

The strategy for generating per-tick label values.

Deserialized via untagged enum: provide either values: [...] or prefix: / cardinality: fields directly alongside key:.
