You can change the cluster multicast port that is used when Foglight is running in High Availability (HA) mode. Members of an HA cluster use this port to communicate with each other. For more information, see the .
Federation is a Foglight feature that addresses the needs of customers who monitor large-scale environments that are naturally partitioned into logical units. Each of these partitions is traditionally served by one Management Server instance and its distributed clients and agents.
Federation enables you to use one Management Server to operate, while using other Management Server as the data source. For detailed information about Foglight federation and how to create a federated environment, see the .
The following default system properties appear in the server.config file. The port setting can be changed during the install process, or by editing the server.config file.
If you are running the Management Server by running bin/fms, you can configure the Java® Virtual Machine’s (JVM) minimum and maximum memory parameters for the server in the <foglight_home>/config/server.config file.
If you are starting Foglight using the run.[bat|sh] command, the JVM heap memory parameters set in the <foglight_home>/config/server.config file do not take effect. Use -X options to pass the memory parameters straight to the VM.
If your installation supports a large number (hundreds) of agents, you can set the Java® heap memory minimum (-Xms) and maximum (-Xmx) options to the same size. For example, assigning 1GB of memory can be set in the server.config file as follows:
NOTE: The -Xms and -Xmx options are different for 32-bit and 64-bit JVMs and available physical memory.
The values of the -Xms and -Xmx options do not necessarily have to be the same size. However, the value of the -Xmx option should not exceed certain limits that the System Administrator specifies.
