Are the passwords that are stored in the configuration file, fglam.config.xml, encrypted?

Certain passwords that are specified (or stored) in the Agent Manager configuration file <fglam_home>/state/<state name>/config/fglam.config.xml are automatically encrypted when the Agent Manager restarts.
The passwords that are encrypted are the ones set as arguments for the proxy-pass, key-password, keystore-password, and truststore-password attributes in fglam.config.xml. These passwords are encrypted after you manually edit them in fglam.config.xml and then restart the Agent Manager.
The passwords stored as arguments for the key-password, keystore-password, and truststore-password attributes are also encrypted when you start an Agent Manager concentrator for the first time after configuring it to communicate with downstream instances using HTTPS. See Creating a Secure Connection with Downstream Instances for more information about this type of configuration.
In addition, you can specify the password that the Agent Manager uses when connecting to the Management Server using a proxy during or after the installation (using the Agent Manager configuration interface). This password is stored in an encrypted form in fglam.config.xml (as the argument for the proxy-pass attribute) when you start the Agent Manager after installation or restart after using the Agent Manager configuration interface. See Configuring Management Server URLs using the installer interface and Configuring Management Server URLs from the Command Line for more information about setting the proxy password through the Agent Manager installer or configuration interface.

How can I see what parameters are available for the silent installers?

You can see the list of parameters available for the silent Agent Manager installer by running the fglam-<version>-<platform> command with the --help option.

Why are two URLs displayed for localhost when I search for HA peers?

If you specify a localhost address as the Management Server URL and then search for HA peers (while installing or configuring the Agent Manager), two URLs appear: one that shows the real machine name and one for localhost.
For example, you are installing the Agent Manager on server1, the same machine on which the Management Server is running. You type localhost and 8080 as the host name and port used by the Agent Manager to connect to the Management Server. After you search for HA peers, two URLs are listed: http://localhost:8080 and http://server1.example.com:8080.

I tested the connection between the Agent Manager and a Management Server, but the Management Server URL failed the connectivity test. Why did this happen?

There are several reasons why a Management Server (or Agent Manager concentrator) URL may fail the connectivity test, including the following:
•
The Management Server is not running. Verify that the Management Server is running by navigating to the Management Server URL in a browser:
<http|https>://<management_server_host_name>:<management_server_port>
If the Management Server is running, the Foglight Login Page appears. If the Login Page does not appear, follow the applicable instructions in “Starting and Stopping the Foglight Management Server” in the Installation and Setup Guide for the platform and database you are running to start the Management Server.
•
The Agent Manager adapter is either deactivated or uninstalled. Verify that the Agent Manager adapter is running by logging in to Foglight and navigating to Dashboards > Administration > Agents > Agent Adapters using the navigation panel.
If the Agent Manager adapter is running, the Agent Manager adapter (named FglAM) is listed in the Agent Adapters table and an Active icon () appears in the row for the adapter.
If the Agent Manager adapter is listed but no Active icon () appears in the row for the adapter, select the adapter and click Activate at the bottom of the dashboard.
If the Agent Manager adapter has been uninstalled (it is not listed in the Agent Adapters table), re-install the Agent Manager cartridge. See Deploying the Agent Manager Cartridge for instructions.
•
You are attempting to connect the Agent Manager to a concentrator or Management Server over HTTPS, but your certificate has expired. Renew your certificate and test the connection again.
•
You are attempting to connect the Agent Manager to a concentrator or Management Server through a proxy configuration but your proxy is rejecting connections. Ensure that the proxy you specify is accepting connections and test the connection again.
