Prior to 0.12.0, Druid used Monitor classes from the `com.metamx.metrics` package. In 0.12.0, these Monitor classes were moved to the Druid repo under `org.apache.druid.java.util.metrics`. In 0.13.0, they were moved again to `org.apache.druid.java.util.metrics`. See https://github.com/apache/druid/pull/5289 and https://github.com/apache/druid/pull/6266 for details. We automatically adjust old package references to `org.apache.druid.java.util.metrics` for backwards compatibility purposes, easing the upgrade process for users.
