Foglight for Virtualization Enterprise Edition 8.9 - Getting Started Guide

Foglight architecture overview

The components described in the preceding sections combine to compose Foglight (as shown in Figure 3).

Users interact with the Management Server and the data collected by the agents through dashboards in the Foglight browser interface, which is built on the Web Component Framework. See the Web Component Guide for more information about the framework and browser interface.

Cartridges are installed onto the Management Server, providing agents, rules, reports, and views specific to the application or technology that the cartridge is designed to monitor.

Agents are deployed to monitored hosts and communicate with the Management Server either directly, or through the Agent Manager.

In order to gain a better understanding of how the Management Server provides a complete view of your monitored system, review the following typical data workflows.

 

 

Installation and Setup Overview

This section provides an overview of the Foglight installation and setup process. It summarizes the main steps involved in installing Foglight and contains directions to instructions in other guides; it is intended as a preface or supplement to these guides.

References to the Installation and Setup Guide set

The Foglight documentation suite includes a multi-guide Installation and Setup Guide set. Throughout this guide, instructions direct you to the Installation and Setup Guide where the same type of information exists in all guides in the set. In these cases, see the Installation and Setup Guide for the database and platform you are running. When information exists only in certain guides, those guides are referred to by name or type.

Before you install Foglight, review the components you plan to install and ensure that you have the necessary information, such as port numbers and server names or the target installation locations.

Before you begin, you must determine if you are going to set up and run the Management Server in High Availability (HA) or standalone mode, and decide whether to use an embedded or external database. For help making these determinations, see “High Availability mode” in the Installation and Setup Guide for running Foglight with an external database and “Using embedded databases” or “Using external databases” in the Installation and Setup Guide for the type of database you plan to run.

Before installing Foglight, review the System Requirements and Platform Support Guide, and “Before installing Foglight” and “Preparing to install” in your Installation and Setup Guide.

Part 1: Installing the Management Server

1
Install the Management Server: Run the installer by following the appropriate set of instructions in “Installing Foglight” in the Installation and Setup Guide.
2
Configure the Management Server and database: Once you install the Management Server, you may need to configure it, change its settings, or perform other additional setup steps. For more information, see “Foglight settings” in the Installation and Setup Guide.
If you are using an external database, see “External database access for remote users” in the Installation and Setup Guide for your platform and external database.
For more information, see “Foglight settings” in the Installation and Setup Guide for the platform and database you are running. See the section “Installing Foglight FAQ” in the Installation and Setup Guide if you encounter problems when performing the steps listed above.

Part 2: Starting Foglight and logging in

Before you begin: For instructions to migrate from using an embedded PostgreSQL® database with the Management Server to using an external PostgreSQL database, see “Appendix: Switching from an Embedded to an External Database” in the Foglight Installation and Setup Guide (for UNIX® or Windows® systems with Embedded PostgreSQL Database).

2
Start the Management Server: The Management Server can be run in standalone mode, in High Availability (HA) mode (with an external database), or as a Windows® service. See “Starting and stopping the Foglight Management Server” in the Installation and Setup Guide and “Running the Foglight Management Server” in the Command-Line Reference Guide.
3
Configure the embedded Agent Manager: In most cases, you do not need to configure the embedded Agent Manager. If you need to configure the embedded Agent Manager, you can do so by running the Agent Manager configuration interface from the embedded Agent Manager installation directory. See “Configuring the embedded Agent Manager” in the Agent Manager Guide for more information.
4
Log in to Foglight: See “Logging in to Foglight” in the User Guide for more information.

See “Running the Foglight Management Server FAQ” in the Installation and Setup Guide if you encounter problems when performing the steps listed above.
