Configuring the Agent Manager to use SSL certificates

Configuring the Agent Manager : Configuring the Agent Manager to use SSL certificates

You can set this option either while installing the Agent Manager, or after installation. See Installing the Agent Manager on page 13, or Configuring the Agent Manager , for more information about configuring the Agent Manager to connect to the Management Server using HTTPS.
By default, Foglight ships with a self-signed SSL certificate. If you configure the Management Server to use an SSL certificate signed by a third-party Certificate Authority (CA), whose root certificate is already included in the JRE used by the Agent Manager, you do not need to add a new CA to the Agent Manager keystore. Instead, ensure that the Agent Manager connects to the Management Server using HTTPS.
keytool --keystore ..\path\cacerts -storepass changeit -list | findstr
<3rd_party_signer>
keytool --keystore ..\lib\security\cacerts -storepass changeit -list | findstr
godaddy
fglam --add-certificate <alias=/path/to/certificate>
If you are using the command-line version of the configuration interface, set the start of the url parameter to https (for example, url=https://server1.example.com:8443).

Configuring an Agent Manager instance as a Concentrator

Configuring the Agent Manager : Configuring an Agent Manager instance as a Concentrator

Your firewall configuration does not allow the Agent Manager instances on your monitored hosts to connect directly to the Management Server (running on ManagementServerHost). However, there is an intermediate host in your environment (IntermediateHost) that can accept connections from your monitored hosts and also communicate with the Management Server.
1
While installing the instance on IntermediateHost (using the GUI installer), you specify the host name and port (ManagementServerHost and 8080) of the Management Server to which you want this concentrator to connect in the Configure Server URLs step.
2
When the installation is complete, you ensure that the instance is shut down and configure it as a concentrator by editing its fglam.config.xml file so that it listens for connections from downstream instances on a specified port (8081).
3
You restart the Agent Manager instance on IntermediateHost. This instance is now configured as a concentrator: it listens for connections from downstream instances on port 8081 and forwards data to the Management Server on port 8080.
Now that the concentrator is set up on IntermediateHost, you configure the Agent Manager instances on the monitored hosts to connect to the concentrator:
2
In the configuration interface, you specify the concentrator’s host name and the port on which it is listening (IntermediateHost and 8081) when setting the URL to which the instances connect.
