- org.springframework.boot.actuate.metrics.statsd.StatsdMetricWriter

All Implemented Interfaces:
Closeable, AutoCloseable, CounterWriter, GaugeWriter, MetricWriter
```
public class StatsdMetricWriter
extends Object
implements MetricWriter, Closeable
```
A MetricWriter that pushes data to statsd. Statsd has the concept of counters and gauges, but only supports gauges with data type Long, so values will be truncated towards zero. Metrics whose name contains "timer." (but not "gauge." or "counter.") will be treated as execution times (in statsd terms). Anything incremented is treated as a counter, and anything with a snapshot value in set(Metric) is treated as a gauge.
Since:
1.3.0

```
public StatsdMetricWriter(String host,
                          int port)
```
    Create a new writer instance with the given parameters.
    Parameters:
    host - the hostname for the statsd server
    port - the port for the statsd server
  - StatsdMetricWriter
```
public StatsdMetricWriter(String prefix,
                          String host,
                          int port)
```
    Create a new writer with the given parameters.
    Parameters:
    prefix - the prefix to apply to all metric names (can be null)
    host - the hostname for the statsd server
    port - the port for the statsd server
  - StatsdMetricWriter
```
public StatsdMetricWriter(com.timgroup.statsd.StatsDClient client)
```
    Create a new writer with the given client.
    Parameters:
    client - StatsD client to write metrics with
- Method Detail
  - increment
```
public void increment(Delta<?> delta)
```
    Description copied from interface: CounterWriter
    Increment the value of a metric (or decrement if the delta is negative). The name of the delta is the name of the metric to increment.
    Specified by:
    increment in interface CounterWriter
    Parameters:
    delta - the amount to increment by
  - set
```
public void set(Metric<?> value)
```
    Description copied from interface: GaugeWriter
    Set the value of a metric.
    Specified by:
    set in interface GaugeWriter
    Parameters:
    value - the value
  - reset
```
public void reset(String name)
```
    Description copied from interface: CounterWriter
    Reset the value of a metric, usually to zero value. Implementations can discard the old values if desired, but may choose not to. This operation is optional (some implementations may not be able to fulfill the contract, in which case they should simply do nothing).
    Specified by:
    reset in interface CounterWriter
    Parameters:
    name - the name to reset
  - close
```
public void close()
```
    Specified by:
    close in interface AutoCloseable
    Specified by:
    close in interface Closeable
