putMetrics

public void putMetrics(MetricsRecord record)

从接口复制的说明: MetricsSink

Put a metrics record in the sink

参数:

record - the record to put

emitMetric

protected void emitMetric(String groupName,
              String name,
              String type,
              String value,

              AbstractGangliaSink.GangliaSlope gSlope)
                   throws IOException

The method sends metrics to Ganglia servers. The method has been taken from org.apache.hadoop.metrics.ganglia.GangliaContext30 with minimal changes in order to keep it in sync.

参数:

groupName - The group name of the metric

name - The metric name

type - The type of the metric

value - The value of the metric

gConf - The GangliaConf for this metric

gSlope - The slope for this metric

抛出:

IOException
