Servo: Application Metrics in Java

servo v. : WATCH OVER, OBSERVE

Latin.

Servo provides a simple interface for exposing and publishing application metrics in Java. The primary goals are:

  • Leverage JMX: JMX is the standard monitoring interface for Java and can be queried by many existing tools.
  • Keep It Simple: It should be trivial to expose metrics and publish metrics without having to write lots of code such as MBean interfaces.
  • Flexible Publishing: Once metrics are exposed, it should be easy to regularly poll the metrics and make them available for internal reporting systems, logs, and services like Amazon CloudWatch.

This has already been implemented inside of Netflix and most of our applications currently use it.

Versioning

Servo is released with a 0.X.Y version because it has not yet reached full API stability.

Given a version number MAJOR.MINOR.PATCH, increment the:

  • MINOR version when there are binary incompatible changes, and
  • PATCH version when new functionality or bug fixes are backwards compatible.

  • Leverage JMX: JMX is the standard monitoring interface for Java and can be queried by many existing tools.
  • Keep It Simple: It should be trivial to expose metrics and publish metrics without having to write lots of code such as MBean interfaces.
  • Flexible Publishing: Once metrics are exposed, it should be easy to regularly poll the metrics and make them available for internal reporting systems, logs, and services like Amazon CloudWatch.
This has already been implemented inside of Netflix and most of our applications currently use it.
