/**
 * Metrics constants interface contains JMS message types
 * used to identify different monitoring point
 * message producers in the server. When publishing a message
 * to the metrics topic, you should type the message source.
 * For example:  <br><pre>
 *
 *      Message myMessage;
 *      myMessage.setJMSType(INVOCATION_METRICS);
 *
 * </pre>
 *
 * In addition, this interface contains some generic JMS property
 * identifiers for the metrics messages.
