Cloud Foundry is an opinionated Platform-as-a-Service that allows you to manage applications at scale. This article is part of a series that explores different facets of a Cloud Foundry deployment using the spring-music project as an example.
This article is Part 5 of a series on Cloud Foundry concepts:
In this particular article, we will look at application level monitoring of CF deployed applications using the New Relic Service Broker. The New Relic product enables real-time monitoring of applications.

ElasticSearch’s Metricbeat is a lightweight shipper of both system and application metrics that runs as an agent on a client host. That means that along with standard cpu/mem/disk/network metrics, you can also monitor Apache, Docker, Nginx, Redis, etc. as well as create your own collector in the Go language.
In this article we will describe installing Metricbeat 5.x on Ubuntu when the back end ElasticSearch version is either 5.x or 2.x.

Java JMX (Java Management Extensions) is a standardized way of monitoring Java based applications. The managed resources (MBeans) are defined and exposed by the JVM, application server, and application – and offer a view into these layers that can provide invaluable monitoring data.
But in order to report back the JMX data you must know the fully expanded path of the MBean and it’s available attributes/operations. If you are on a desktop, tools like jsonsole provide a nice GUI interface for drilling down into the MBean hierarchy. But, if you are in a server environment and JMX is not enabled for remote access on a desktop, you may need a console alternative.
An open-source project call jmxterm comes packaged as a single uber jar that makes it easy to enumerate and explore the available MBean exposed in a Java based application.
