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. | |
Collects MBean attribute data from a specified MBean server. For more information, see About the JMX 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. | |
A model that specifies the MBean data to collect from the monitored server. | |
The JMX specification defines five types of MBean: Standard, Dynamic, Open, Model, MXBeans. | |
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). |
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.
