/**
* This class defines a monitor entry that provides information about the system
* and JVM on which the Directory Server is running.
*
*
* NOTE: This class, and other classes within the
* {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
* supported for use against Ping Identity, UnboundID, and
* Nokia/Alcatel-Lucent 8661 server products. These classes provide support
* for proprietary functionality or for external specifications that are not
* considered stable or mature enough to be guaranteed to work in an
* interoperable way with other types of LDAP servers.
*
*
* The information that may be available includes:
*
*
The name of the operating system on which the server is running.
*
The number of CPUs available to the JVM.
*
The Java classpath in use by the server.
*
The amount of memory currently used by the JVM.
*
The maximum amount of memory that the JVM will be allowed to use.
*
The amount of memory held by the JVM that is marked as "free" and can
* be used to allocate new objects.
*
The hostname for the underlying system.
*
The location in which the server is installed on the
* underlying system.
*
The current working directory for the server process.
*
The path to the Java installation being used to run the server.
*
The vendor that provides the Java installation being used to run the
* server.
*
The Java version string for the Java installation being used to run
* the server.
*
The vendor that provides the JVM being used by the Java installation
* being used to run the server.
*
The JVM version string for the Java installation being used to run the
* server.
*
The JVM architecture data model (i.e., whether it is a 32-bit or 64-bit
* JVM).
*
The arguments provided to the JVM when running the server.
*
* The server should present at most one system info monitor entry. It can be
* retrieved using the {@link MonitorManager#getSystemInfoMonitorEntry} method.
* This entry provides specific methods for accessing this system information
* (e.g., the {@link SystemInfoMonitorEntry#getOperatingSystem}
* method can be used to retrieve the name of the operating system).
* Alternately, this information may be accessed using the generic API. See the
* {@link MonitorManager} class documentation for an example that demonstrates
* the use of the generic API for accessing monitor data.
