    public class MetricsTimeVaryingInt

extends MetricsBase

The MetricsTimeVaryingInt class is for a metric that naturally varies over time (e.g. number of files created). The metrics is accumulated over an interval (set in the metrics config file); the metrics is published at the end of each interval and then reset to zero. Hence the counter has the value in the current interval. Note if one wants a time associated with the metric then use

    public MetricsTimeVaryingInt(String nam,
                                 MetricsRegistry registry,
                                 String description)

  Deprecated.
  Constructor - create a new metric

  Parameters:
    `nam` - the name of the metrics to be used to publish the metric
    `registry` - - where the metrics object will be registered
    `description` - - the description

### MetricsTimeVaryingInt

    public MetricsTimeVaryingInt(String nam,
                                 MetricsRegistry registry)

  Deprecated.
  Constructor - create a new metric

  Parameters:
    `nam` - the name of the metrics to be used to publish the metric
    `registry` - - where the metrics object will be registered A description of `MetricsBase.NO_DESCRIPTION` is used

Method Detail

### inc

    public void inc(int incr)

  Deprecated.
  Inc metrics for incr vlaue

  Parameters:
    `incr` - - number of operations

### inc

    public void inc()

  Deprecated.
  Inc metrics by one

### pushMetric

    public void pushMetric(MetricsRecord mr)

  Deprecated.
  Push the delta metrics to the mr. The delta is since the last push/interval. Note this does NOT push to JMX (JMX gets the info via `previousIntervalValue`

  Specified by:
    `pushMetric` in class `MetricsBase`
  Parameters:
    `mr` -

### getPreviousIntervalValue

    public int getPreviousIntervalValue()

  Deprecated.
  The Value at the Previous interval

  Returns:
    prev interval value

### getCurrentIntervalValue

    public int getCurrentIntervalValue()

  Deprecated.
  The Value at the current interval

  Returns:
    prev interval value
