Class OrderedObjectNameMapper

java.lang.Object

com.netflix.servo.jmx.OrderedObjectNameMapper

All Implemented Interfaces:

ObjectNameMapper

public final class OrderedObjectNameMapper
extends java.lang.Object
implements ObjectNameMapper

An ObjectNameMapper that allows the order of tags to be specified when constructing the ObjectName. The mapper will map the known ordered tag keys and then optionally append the remaining tags. While an ObjectName's properties are meant to be unordered some visual tools such as VisualVM use the given order to build a hierarchy. This ordering allows that hierarchy to be manipulated.

It is recommended to always append the remaining tags to avoid collisions in the generated ObjectName. The mapper remaps any characters that are not alphanumeric, a period, or hypen to an underscore.
