Controls how Prometheus handles conflicts between labels that are already present in scraped data and labels that Prometheus would attach server-side ("job" and "instance" labels, manually configured target labels, and labels generated by service discovery implementations).
If honor_labels is set to "true", label conflicts are resolved by keeping label values from the scraped data and ignoring the conflicting server-side labels.
If honor_labels is set to "false", label conflicts are resolved by renaming conflicting labels in the scraped data to "exported_\<original-label\>" (for example "exported_instance", "exported_job") and then attaching server-side labels. This is useful for use cases such as federation, where all labels specified in the target should be preserved.
Defaults to false in prometheus when set to null.
