Configuring the database start up and shut down grace periods

There are also optional settings for configuring the startup and shutdown grace periods for the embedded database: server.database.embedded.startup.grace and server.database.embedded.shutdown.grace.

Foglight starts and stops the embedded database. These settings control the length of time that Foglight waits before considering an attempt to start or stop the database to have failed.

The values for these optional settings are specified in seconds, as in the default values shown in the following example.

server.database.embedded.startup.grace = "300";

server.database.embedded.shutdown.grace = "300";

Understanding the Password and Socket settings

The file server.config also contains parameters that set the password and socket that the embedded database uses.

The password that the server.database.embedded.password parameter specifies is the root password used for the embedded database. The default value is foglight.

If you selected the embedded database option while installing Foglight and now want to switch to using an embedded database, you do not need to change the root password.

If you did not select the embedded database option during installation, you need to specify the correct root password as the value of server.database.embedded.password. This password can be specified in either an encrypted or plain-text format. If necessary, you can encrypt the password using the <foglight_home>/bin/ tool.

During installation, the Foglight installer overwrites the default value of server.database.embedded.password when you select the embedded database.

The server.database.embedded.socket parameter specifies a UNIX® domain socket. This parameter is used on Linux® and Solaris platforms only. The installer generates a unique socket name for each installation.

Configuring ports

You can set a number of different ports using the file <foglight_home>/config/server.config, including mandatory ports required for Foglight to run.

For a list of these ports, their default values, and the configuration parameters you can use to set them in server.config, see the Administration and Configuration Help.

Setting memory parameters for the server

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:

server.vm.option0 = “-Xms1280M”;
server.vm.option1 = “-Xmx1280M”;

Ensure that you uncomment these lines in the file.

You can set up to 100 VM options in total.

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.
