After deploying the FglAM-[all|<platform>]-<version>.car file on the Management Server, you can download the appropriate platform-specific installer to the target system from the Components for Download dashboard.
2
Navigate to the Components for Download dashboard (Dashboards > Administration > Cartridges > Components for Download).
<hostname> is the name of the machine where the Management Server is installed.
<port> is the HTTP port specified during installation (the default is 8080).
2
Navigate to the Agent Managers or Agent Status dashboard (Dashboards > Administration > Agents> Agent Managers or Agent Status).
3
In the top right corner, click Download Agent Manager Software.

Click Download to start the process.
<hostname> is the name of the machine where the Management Server is installed
<port> is the HTTP port specified during installation (the default port is 8080)
<version> is the version of the Agent Manager
<platform> is the appropriate Agent Manager installer for your operating system
For example, to retrieve the file fglam‑5_8_5_5‑linux‑ia32.bin from a machine called server1, that uses the default port 8080, using Wget, issue the following command:
wget -O fglam‑5_8_5_5‑linux-ia32.bin "http://server1:8080/console/installer/download-installer.action?downloadId=fglam‑5_8_5_5‑linux‑ia32.bin"

Installing external Agent Managers : Installing the Agent Manager : Installing the Agent Manager using the installer interface

To install the Foglight Agent Manager using the Agent Manager Installation and Configuration interface:
NOTE: On UNIX® platforms, if necessary, change the permissions for the installer file so that it is executable (as described in To download and run the Agent Manager installer using the Agent Managers or Agent Status dashboard: ).
IMPORTANT: On Windows® 7 and Vista, you must run the installer GUI as an administrator if you want it to automatically install the Agent Manager as a service. To do so, right-click the installer executable and select Run as Administrator.
The Agent Manager installation program consists of several steps. Each installation screen includes a Previous button, allowing you to go back and adjust the information you specified.
The Agent Manager Installation and Configuration window opens, showing the Introduction step.
Read the information in the Introduction step and click Next.
Read the information in the License Agreement step, enable the check box to accept the terms of the license agreement, then click Next.
NOTE: If you are running an AIX® operating system with IPv6 support enabled and the Agent Manager installer detects problems resolving IP addresses and host names, an AIX compatibility warning appears. This warning provides information about an alternate command-line option for running the installer and a URL that you can consult for more information. See Frequently asked questions for more information.
In the Choose Install Location step, choose the directory where you want to install the Agent Manager and click Next.
The Host Display Name step allows you to configure the host name that the Agent Manager uses to identify itself. This is also the name under which the Agent Manager submits metrics to the Management Server.
The Server URLs step provides multiple ways to configure the connection between the Agent Manager and the Management Server. For example, you can specify the URL of a single Management Server to which you want the Agent Manager to connect, or configure multiple Management Server URLs for failover purposes. You can also specify the URL of an Agent Manager concentrator to which you want the Agent Manager to connect.
TIP: To complete this configuration, you must clear the Connect Using HTTPS check box in Step 2.
2
In the Server URLs step, click Add.
a
In the Edit Server URL dialog box that appears, specify the host name and port number that you want the Agent Manager to use when connecting to the Management Server.
TIP: This option is only available if you selected Allow Unsecured Connections in Step 1.
Repeat these steps for each Management Server URL that you want to add. As you add the URLs, they appear listed in the Server URLs step. If you want to remove a URL, select the URL from the list and click Delete.
3
Test the connection between the Agent Manager and the Management Server. Select a URL in the list and click Test. An icon on the left of each URL indicates if the URL is tested and the outcome of the connection test:
See Frequently asked questions for information about why the URL may fail the connectivity test.
5
The Manage SSL Certificates dialog box appears. Use this dialog box, to add and remove SSL certificates from trusted certificate authorities. Only certificates that you manually add appear in this list. The default set of trusted CA certificates is not included. For more information, see Configuring the Agent Manager to use SSL certificates.
a
Click Add.
c
In the SSL Certificate Alias dialog box, type a name (alias) to identify the certificate you are adding, and click OK.
A summary of the new certificate appears in the Manage SSL Certificates dialog box.

UNIX® platforms only.
The Configure Secure Launcher step allows you to configure the external loader used by the Agent Manager to provide certain Foglight agents with permissions required to gather system-level metrics. See Configuring Agent Manager agent privileges for more information.
1
In the Configure Secure Launcher step, complete one of the following steps:
The UNIX init.d Script step allows you to configure the Agent Manager to run as a daemon. You do that by instructing the installer to installing an init.d-style script called dell-fglam in the init.d directory on your system. See Locating the init.d script for the location of this directory on your operating system.
The system calls the dell-fglam script when the host on which the Agent Manager is installed starts up or shuts down.
1
In the UNIX init.d Script step, complete one of the following steps:
If you want to use the default configuration options, ensure the Would you like to customize the start-up script check box is cleared, and click Next. Then, continue to Step 8: Downstream Connection Configuration.
To apply customized configuration options, click the Would you like to customize the start-up script check box, and proceed to Step 2.
To install the script, select the Yes, install init.d scripts check box.
If you do not want to install the scripts, ensure that the Yes, install init.d scripts check box is clear (the default setting).
NOTE: Even if you choose not to install the init.d script, or if you are not performing the installation as the root user, two scripts to perform the necessary setup are generated for later use. See Configuring the Agent Manager to run as a daemon for more information.
If you are not installing the init.d script at this time, it is recommended to configure as many options as possible in this step. They are referenced when generating these scripts for a later use.
3
Linux only. If the correct operating system is not auto-detected by the installer, from the Select OS Type menu, select your OS.
4
In the Run as user box, type the name of the user account used to run the Agent Manager.
6
If you want the Agent Manager to start immediately after the installation, ensure that Start Foglight Agent Manager at the end of the installation is selected.
NOTE: If the installer is started on the command line with the --no-start-on-exit option, this check box does not appear selected in the Install init.d Script step. Starting the installer without the --no-start-on-exit option causes the Start Foglight Agent Manager at the end of the installation check box to be selected by default. For more information, see Installing the Agent Manager using the installer interface.

Click Next.
If the user specified in the Run as user box is not a local user, the installer displays a Warning and prompts you for further actions.

Windows® platforms only.
The Windows Service step allows you to specify if you want to install the Agent Manager as a Windows service. A Windows service operates in the background while the system on which it is installed is running. Installing the Agent Manager as a Windows Service causes the Agent Manager to start automatically on your system startup.
1
In the Windows Service step, complete one of the following steps:
NOTE: If the installer is started on the command line with the --no-start-on-exit option, this check box does not appear selected in the Windows Service step. Starting the installer without the --no-start-on-exit option causes the Start Foglight Agent Manager Windows Service at the end of the installation check box to be selected by default. For more information, see Installing the Agent Manager using the installer interface.
