+  pod_label_tags_prefix: VALUE
+----
+| Pods might have one or more labels (name/value pairs). You can tag each metric with these pod labels if "pod_label_tags_prefix" is not an empty string. If it is an empty string or not specified, these tags will not be created. When not an empty string, for each label on a pod a tag will be placed on each pod metric with this string prefixing the pod label name. For example, if the prefix string is `labels.` and a pod has a label `something=foo` then that pod's metrics will have a tag named `labels.something` with value of `foo`. If you wish to create these tags with no prefix (that is, you want the tag names to be exactly the same as the label names) set the prefix value to `\_empty_`.
