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