Prometheus.spec.enforcedLabelNameLengthLimit
enforcedLabelNameLengthLimit when defined specifies a global limit on the length of labels name per sample. The value overrides any `spec.labelNameLengthLimit` set by ServiceMonitor, PodMonitor, Probe objects unless `spec.labelNameLengthLimit` is greater than zero and less than `spec.enforcedLabelNameLengthLimit`. It requires Prometheus >= v2.27.0. When both `enforcedLabelNameLengthLimit` and `labelNameLengthLimit` are defined and greater than zero, the following rules apply: * Scrape objects without a defined labelNameLengthLimit value will inherit the global labelNameLengthLimit value (Prometheus >= 2.45.0) or the enforcedLabelNameLengthLimit value (Prometheus < v2.45.0). If Prometheus version is >= 2.45.0 and the `enforcedLabelNameLengthLimit` is greater than the `labelNameLengthLimit`, the `labelNameLengthLimit` will be set to `enforcedLabelNameLengthLimit`. * Scrape objects with a labelNameLengthLimit value less than or equal to enforcedLabelNameLengthLimit keep their specific value. * Scrape objects with a labelNameLengthLimit value greater than enforcedLabelNameLengthLimit are set to enforcedLabelNameLengthLimit.
