This guide provides instructions for installing, configuring, and starting the Foglight™ Agent Manager. Before you begin, refer to the Foglight System Requirements and Platform Support Guide, and the Foglight Installation and Setup Guide set.
This guide provides installation instructions for both Windows® and UNIX® operating systems. Commands are listed separately for each OS. Generic examples follow the UNIX path structure that uses forward slashes '/' to separate directories; substitute the back slash where necessary for your operating system.
An instance of the Foglight™ Agent Manager is automatically installed with new installations of the Foglight Management Server. This embedded Agent Manager instance runs on the Management Server machine. You can deploy agents to the embedded Agent Manager if you want to monitor the machine on which the Management Server runs.
The embedded Agent Manager does not start automatically when:
• |
Foglight is installed in High Availability (HA) mode. If you want to run the Agent Manager on the Management Server machines in your HA cluster, you must install, configure, and run separate (non-embedded) Agent Manager instances on these machines. See Installing external Agent Managers for instructions. For more information about High Availability mode, see the High Availability Field Guide. |
• |
The Management Server is a Federation Master. The embedded Agent Manager does not start if you install Foglight as a Federation Master. See the Federation Field Guide for more information about federation. |
If you are running the Management Server as a Windows® service, the embedded Agent Manager continues to run when you log out of the machine on which the embedded Agent Manager and the Management Server are running.
An embedded instance of the Agent Manager automatically installs with the Management Server. You can deploy agents to the embedded Agent Manager. You can specify whether or not the embedded Agent Manager runs in tandem with the Management Server by changing the value of the server.fglam.embedded parameter in the server.config file.
2 |
On the Management Server machine, open <foglight_home>/config/server.config for editing. |
3 |
Set the parameter server.fglam.embedded to the desired value: |
• |
To have the embedded Agent Manager stop and start automatically with the Management Server, set server.fglam.embedded to true. |
• |
4 |
Save your changes to the server.config file. |
You can run the configuration interface from the embedded Agent Manager installation directory, <foglight_home>/fglam/bin.
1 |
IMPORTANT: On UNIX® platforms, if you attempt to run the installation interface, and the DISPLAY environment variable is not set on the machine, the Agent Manager defaults to the command-line interface. |
4 |
Follow the appropriate set of instructions provided in To launch the Agent Manager Installation and Configuration interface: or To launch the Agent Manager configuration command-line interface: for proceeding through the configuration interface steps. |
When configuring the embedded Agent Manager, you do not need to set the host name and port number of the Management Server with which it communicates. The embedded Agent Manager automatically sets the host name and port number of the Management Server that starts it in its configuration file, fglam.config.xml, which is located in the <foglight_home>/fglam/state/default/config/ directory.
