Class MetricTags

  • public final class MetricTags
extends java.lang.Object
    Metric descriptors are formed from a comma separated list of tag_name=tag_value pairs. The constants defined here are the possible tag names that are used in Jet. See individual descriptions for the meaning of information carried by each tag.
    Since:
    Jet 3.2
