Foglight for Java EE Technologies 5.9.13 - Administration and Configuration Guide

Introducing Application Servers Administration

This Foglight for Application Servers Administration and Configuration Guide provides configuration instructions, conceptual information, and instructions on how to configure and manage the Nexus and related recording settings for Foglight for Java EE Technologies and Foglight for Microsoft .NET.

This guide is intended for administrators to manage and configure the Nexus, and complete other administration and configuration tasks that are common to Foglight for Java EE Technologies, Foglight for Microsoft .NET, and Foglight for JMX.

The Application Servers Administration dashboard provides a central location for creating and managing your .NET, JMX, Java, and Nexus agents. When you install Foglight for JMX, Foglight for Microsoft .NET, or Foglight for Java EE Technologies, this dashboard becomes available. Use it to create and manage agents and application server integrations, as well as to review the recent history of application server agent-related tasks.

Application server administration dashboards

Use the links at the top of the dashboard to manage installation, configuration, and integrations for specific agent types:

•
.NET Administration — For more information about creating and configuring .NET agents, see the Foglight for Microsoft .NET Installation and Configuration Guide.
•
Java Administration — For more information about creating and integrating Java EE agents with Java application servers, see the Foglight for Java EE Technologies Installation Guide.
•
JMX Administration — For more information about creating and managing JMX agents, see the Foglight for JMX User Guide.
•
Nexus Administration — For more information about creating and managing Nexus agents, see Introducing the Nexus .

The lower portion of the dashboard is divided into two sections: Monitoring agents and Task history.

Monitoring agents

The Monitoring Agents section of the Application Servers Administration dashboard lists all .NET, JMX, and Java EE agents, along with the type of application server they are monitoring, their version, health and collection status, and other relevant information.

Use this list instead of the Foglight Agent Status and Agent Properties dashboards to quickly review and manage agent health and configurations.

From here you can:

•
Click Refresh to ensure that you are viewing the latest agent status.
•
Click Setup agents to open a list of agent types that you can create. For detailed instructions on creating agents of a particular type, see the installation guide for that agent type. For more information, see Application server administration dashboards.
•
Click the Name of an agent in the list to open a menu that enables you to perform the following activities:
•
Activate or deactivate the agent
•
Stop or start data collection
•
Open a copy of the agent log
•
Edit or switch configurations
•
Switch the server domain (.NET agents only)
•
Delete the agent
•
View the agent properties
Task history

The Task History section of the Application Servers Administration dashboard lists all application server agent-related tasks, including the date and time the task was submitted, a description of the task, the results of the task, and the user who submitted the task.

This table is also available on the .NET Administration, Java Administration, JMX Administration, and Nexus Administration pages.

To clear the list:
1
Select one, several, or all rows in the table.
2
Click Clear.

Introducing the Nexus

Introducing the Nexus
 
* 
NOTE: Foglight for JMX does not use or require a Nexus. The JMX agents submit data through the Agent Manager directly.

The Nexus is a central analytical engine that correlates data sent from multiple agents, restores and preserves the temporal order of events across all servers, and provides other basic analysis of the data. The Nexus is essential to the data management facilities of Foglight for Java EE Technologies and Foglight for Microsoft .NET.

The Nexus reconstructs the full application-level execution path by organizing the collected data into service requests using Quest’s Tag and Follow® technology. It receives data collected from the agents, then combines and converts agent-based event information into a cohesive information set that Foglight queries and presents graphically.
