The Server Information page displays information about the currently executing
EDG instance and its environment (web container, Java virtual machine,
operating system, etc.).

Memory Management
^^^^^^^^^^^^^^^^^
The Memory Management page provides a detailed report on the current memory usage.
The report also includes a link to request garbage collection to clean up the
Java virtual machine's memory heap. The following are the descriptions of the
displayed values:

* **In-use** - The amount of memory in the Java Virtual Machine that is currently
  used by EDG.

* **Total** - The total amount of memory in the Java Virtual Machine.
  The value may vary over time, depending on the host environment.

* **Max** - The maximum amount of memory the Java Virtual Machine will attempt to use.
  This is determined by the value of the Java Virtual Machine ``-Xmx``
  command-line option.

* **Free** - The amount of free memory in the Java Virtual Machine.


.. _view_edg_log:

View EDG Log
^^^^^^^^^^^^
The Log page displays a filterable view of the current EDG log,
including warnings and errors from the Web application container (typically, Tomcat).
