Class SystemInfoMonitorEntry

  • All Implemented Interfaces:

    @NotMutable
@ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class SystemInfoMonitorEntry
extends MonitorEntry
    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 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 MonitorManager.getSystemInfoMonitorEntry(com.unboundid.ldap.sdk.LDAPConnection) method. This entry provides specific methods for accessing this system information (e.g., the 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 MonitorManager class documentation for an example that demonstrates the use of the generic API for accessing monitor data.
