方法详细资料

• setGroups

  public void setGroups​(Set<String> groups)

  The groups to export.

  参数:

  groups - the groups to set

• groups

  protected Iterable<String> groups()

  从类复制的说明: AbstractMetricExporter
  Generate a group of metrics to iterate over in the form of a set of Strings (e.g. prefixes). If the metrics to be exported partition into groups identified by a String, subclasses should override this method. Otherwise the default should be fine (iteration over all metrics).

  覆盖:

  groups 在类中 AbstractMetricExporter

  返回:

  groups of metrics to iterate over (default singleton empty string)

• next

  protected Iterable<Metric<?>> next​(String group)

  从类复制的说明: AbstractMetricExporter
  Get the next group of metrics to write.

  指定者:

  next 在类中 AbstractMetricExporter

  参数:

  group - the group name to write

  返回:

  some metrics to write

• write

  protected void write​(String group,
                       Collection<Metric<?>> values)

  从类复制的说明: AbstractMetricExporter
  Write the values associated with a group.

  指定者:

  write 在类中 AbstractMetricExporter

  参数:

  group - the group to write

  values - the values to write
