Deploying the Agent Manager to Large-Scale Environments

 
* 
IMPORTANT: The Agent Manager deployment script discussed in this section is provided as an example only, and is not supported as part of the product warranty.
This section contains tips for deploying the Foglight™ Agent Manager to a large number of UNIX® or Windows® hosts in your environment. It also discusses some of the deployment options you might want to consider.
Deploying the Foglight Agent Manager is a multi-step process that includes selecting and deploying an Agent Manager cartridge, downloading the Agent Manager installer, and installing the Agent Manager. The steps in this process are described in Installing External Agent Managers .
If you are planning to deploy the Agent Manager to multiple UNIX hosts, you can create a deployment script to simplify this process. An example of this type of script is outlined below, along with suggestions for how you could customize the script to suit your environment.
If you are planning to deploy the Agent Manager to multiple Windows hosts, it is likely that you need a software deployment tool. Suggestions for using this type of tool are provided below.

Using Agent Manager Silent Installer Parameters

The instructions in this section include references to the Agent Manager silent installer parameters.
These parameters are used with the --silent command option when you run the Agent Manager installer non-interactively—for example, to install the Agent Manager from the command-line onto remote machines, as described in the examples in this section.
SeeUsing the Agent Manager Silent Installer for more information about these parameters.
 
* 
CAUTION: As with deploying the Agent Manager to multiple hosts, using the silent installer is an advanced activity.

Example: Deploying the Agent Manager to Multiple UNIX Hosts

If you are planning to deploy the Agent Manager to multiple UNIX® hosts, you can simplify the process by creating a deployment script that downloads installers, installs, and starts the Agent Manager on these hosts.
This section provides an example of this type of script and suggestions for customizing it to suit your environment.

Working with this Example

This example is based on using the Wget network utility to download Management Server installers, providing a specific set of configuration options with the Agent Manager silent installer command, and using passwords to log in to remote hosts over SSH.
However, you could instead create a script that works with any file-retrieval tool that downloads content using HTTP, such as cURL or a Perl script that uses the LWP::Simple interface.
Additionally, if you require non-default silent installer parameters, such as those used to connect to the Management Server through a proxy, you could edit the parameters used when invoking the Agent Manager silent installer to suit your environment. See Using Agent Manager Silent Installer Parameters for more information.
The end of the example, Part 5: Run the Script , describes using one type of login method (passwords) for connecting to remote machines using SSH. However, if you have private keys configured in your environment, you might encounter different scenarios when establishing an SSH connection, which are described in Part 5: Run the Script .
 
* 
CAUTION: Using a deployment script for the Agent Manager is an advanced activity. You should create and use this type of script only if both of the following conditions apply:
•
You are a Foglight™ administrator who is familiar with configuring the Agent Manager
•
You are certain of the setup that is required for your environment.
 
* 
NOTE: If you are not certain which installation options you need, use the Agent Manager Installation and Configuration or command-line installer on each machine, instead.
