Setting Up vFoglight Server Federation

Federation is useful for customers who monitor large scale environments that are

naturally partitioned into logical units. Each of these partitions is normally served by

one vFoglight Management Server instance and its distributed clients/agents. These

Management Server instances together can act as a single logical Management Server

by making each instance a Federated Management Server with one central Federation

Management Server.

For more detailed background information on vFoglight Federation, please refer to the

vFoglight Federation Field Guide.

To create a Federated environment, you must make changes to both the

foglight.config

and the

federation.config

files after installation.

Caution A Federated server must always be started with the federation parameter set to true.

To set up a Federated environment:

Identify the vFoglight Management Server you wish to define as the Federated

manager or master server.

Copy the ...\vFoglight\tools\foglight-federation-support.sar file into

the ...\vFoglight\server\default\deploy-foglight directory.

Edit the following line in the foglight.config file by changing the variable from

false to true:

# foglight.federation is a boolean parameter that indicates

whether the

# server should start in the "federation" mode. The default value

is false.

foglight.federation = true;

Start your master server.

Open the ...\vFoglight\config\federation.config file.

Add the port number of each vFoglight Management Server in the federation to

the federation.config file. The following example is provided in the

federation.config file:

# *** JndiURLs ***

# This list contains JNDI provider URLs for federated servers.
