registerIfNotExist

public io.prometheus.client.Collector registerIfNotExist(String metricName,
 io.prometheus.client.Collector collector)

从类复制的说明: FunctionCollectorRegistry

Register a metric if it does not yet exist. If it does exist, then return the existing metric. Currently, only needed by the LocalRunner when running in threaded and exposing metrics via a http server. This method helps resolve the conflict in which multiple instances within the LocalRunner process try to register the same metric.

指定者:

registerIfNotExist 在类中 FunctionCollectorRegistry

参数:

metricName - the name of the metric

collector - the metric object e.g. Count, Gauge, etc.

返回:

If the metric with the name `metricName` already exists, return the existing metric object. If not, return null
