Examples of org.apache.hadoop.hdfs.server.namenode.metrics.FSNamesystemMetrics

org.apache.hadoop.hdfs.server.namenode.metrics.FSNamesystemMetrics
This class is for maintaining the various FSNamesystem status metrics and publishing them through the metrics interfaces. The SNamesystem creates and registers the JMX MBean.
This class has a number of metrics variables that are publicly accessible; these variables (objects) have methods to update their values; for example:
{@link #filesTotal}.set()

    // We wrap to bypass standard mbean naming convention.
    // This wraping can be removed in java 6 as it is more flexible in 
    // package naming for mbeans and their impl.
    StandardMBean bean;
    try {
      myFSMetrics = new FSNamesystemMetrics(conf);
      bean = new StandardMBean(this,FSNamesystemMBean.class);
      mbeanName = MBeanUtil.registerMBean("NameNode", "FSNamesystemState", bean);
    } catch (NotCompliantMBeanException e) {
      e.printStackTrace();
