Key Concepts and Terms for Foglight for JMX

This section provides a short list of terms used to describe concepts and components specific to Foglight for JMX.

Derived Metrics

A metric is a specific value that is measured over time. There are two types of metrics in Foglight for JMX: raw metrics and derived metrics. Raw metrics are collected directly from the monitored environment and sent to the Foglight for JMX Management Server. Derived metrics are calculated from one or more raw or derived metrics. They are scoped to a topology type and can optionally be scoped to specific objects of that type. For more information about metrics, see the Foglight for JMX Administration and Configuration Help.

Exposed Relationships

An MBean relationship can be left unexposed, exposed as a reference relationship, or exposed as a containment relationship. References are usually made between a parent and child. Containment is useful where the health of the children impacts the health of a parent.

JMX Agent

Collects MBean attribute data from a specified MBean server. For more information, see About the JMX Agent.

JMX Discovery Agent

Discovers processes running on a target host and enables the JMX Agent to moniter them. For more information, see About the JMX Discovery Agent.

MBean

An MBean is a managed Java object that follows the design patterns set forth in the JMX specification. An MBean can represent a device, an application, or any managed resource. MBeans expose a management interface that consists of: a set of readable or writable attributes (or both), a set of invocable operations, and a self-description.

MBean Server

A managed object server in which MBeans are registered.

MBean Server Model

A model that specifies the MBean data to collect from the monitored server.

MBean Type

The JMX specification defines five types of MBean: Standard, Dynamic, Open, Model, MXBeans.

Observations

The collection of information over time. Observations can be of any type of object. The scope and quality of the information returned by an observation is determined by the time range used to retrieve the information.

Storage Types

There are three storage types available: metrics (numbers only), single value (any data type where only the current value is stored, usually reserved for configuration data (that is, data that doesn't change frequently)), and observations (any non-numeric data that changes over time and where a history is stored, such as a boolean).

About the JMX Agent

The JMX Agent can be used to collect monitoring data locally or remotely. This agent is a management entity that runs on a Java Virtual Machine (JVM). The JMX agent uses the standard remote method invocation (RMI) protocol to expose objects on the MBean server and collect the data.

All of the exposed data on an MBean server can be gathered by a JMX agent. Using the JMX Administration dashboard, you can specify which instances are collected and displayed in the Application Servers Monitor dashboard and the JMX Explorer dashboard.

After you create and configure the JMX agent, MBean data, JMX server data, and application server metrics appear in the Application Servers Monitor dashboard.

About the JMX Discovery Agent

The JMX Discovery Agent performs local process discovery on the monitored host. This allows the JMX Agent to scan for processes running on one or more target machines. You can select one or more processes, identify properties of interest, and select MBean instances to monitor.

Installing the Foglight Cartridge for JMX

Verify that your Foglight system meets the minimum hardware and software requirements before attempting to install and run Foglight for JMX.

The supported platforms and servers specifications for Foglight for JMX are outlined in Foglight for JMX System Requirements .

The installation process is common to all Foglight for JMX cartridges. You must install the cartridge *.car file and then one or more create JMX agents. For instructions for installing and enabling the cartridge, see “Installing Foglight cartridges” in the Administration and Configuration Help.

On the navigation panel, under Dashboards, click Administration > Cartridges > Cartridge Inventory.

If you want to use local process discovery, you must deploy the Discovery Agent package, and create and activate a Discovery Agent. For more information, see Creating JMX Agents Using Local Process Discovery.

For an overview of using the Application Servers Administration dashboard to create agents, see Creating JMX Agents .
