                                  MetricLevel metricLevel,
                                  String... tags)

Get counter. return if exists, create if not.

参数:

name - the name of name

metricLevel - the level of name

tags - string pairs, like sg="ln" will be "sg", "ln"

createCounter

protected abstract Counter createCounter(MetricInfo metricInfo)

getOrCreateAutoGauge
