Process heap use

When a thread is created and run, a run-time stack is dynamically allocated from the native process heap (not the Java® heap). This native heap requires a large contiguous memory block. If the system you are running does not have enough RAM, or if the operating system cannot find a large enough contiguous memory block, new native threads cannot be created and a java.lang.OutOfMemoryError occurs.

If the VM generates errors relating to a failure to allocate native resources, or relating to exhaustion of process address space, you must increase the native process heap size. Errors appear as a Java VM internal error message or a detail message associated with an out-of-memory error. Messages with the relevant errors indicate that the problem is process heap exhaustion.

You cannot directly set the size of the process heap. The process heap uses memory within the 32-bit address space not used by the garbage-collected heap. To increase the size of the process heap, decrease the maximum Java heap size using the -Xmx option in the server.config file.

Default stack size

The default stack size can be adjusted with the ‑Xss option.

Adding command-line options

The server.config file allows you to add up to 10 command-line options for the fms command.

Each command-line argument corresponds to a space-delimited argument passed to the Foglight process.

For example, the following lines in the <foglight_home>/config/server.config file:

server.cmdline.option0 = "--name";
server.cmdline.option1 = "process_name";

Correspond to this direct argument on the command line:

fms --name process_name

Certain arguments can be specified in a single line that uses the long name for an option. For example:

server.cmdline.option0 = "--host=hostname";

Which corresponds to the following command-line argument:

fms --host=hostname

Binding the Management Server to an IP address

To cause the Foglight Management Server to bind to a specific IP address, use the dedicated properties in the <foglight_home>/config/server.config file. For example:

server.bind.address = “192.0.2.2";

server.remote.address = “host1.example.com";

Where host1.example.com is the host name assigned to the bind address in DNS. If no DNS name is available, a raw IP address can be used in this property.

Binding Foglight to a specific IP address can be used where, for example, the same IP address is to be used by multiple Management Server instances on a single host, each IP address delineating a virtual boundary between instances. In such situations, the Management Server will only listen for incoming TCP traffic on that specific IP address. By default, the Management Server listens to all IPv4 and IPv6 addresses.

Configuring Foglight to use stronger encryption

Foglight Management Server 5.6.3 and later includes unlimited strength security policies. In some cases, such as Credential Management, this encryption level may be insufficient. If 256‑bit (or higher) AES keys are necessary, use the following procedure to configure the Management Server to use stronger encryption.

To configure Foglight to use stronger encryption:
1
Stop the Management Server.
2
Open the file <foglight_home>/config/server.config on the Management Server machine.
3
Set the java system property foglight.credentials.enc.key.size to 256 (or higher):
server.vm.option0 = "-Dfoglight.credentials.enc.key.size=256";
4
Save the server.config file.
5
Restart the Management Server.
