diagnostics_channel.tracingChannel(nameOrChannels)

• nameOrChannels <string> | <TracingChannel> 包含所有 TracingChannel 通道 的通道名称或对象

  ¥nameOrChannels <string> | <TracingChannel> Channel name or object containing all the TracingChannel Channels

• 返回：<TracingChannel> 要跟踪的渠道集合

  ¥Returns: <TracingChannel> Collection of channels to trace with

为给定的 TracingChannel 通道 创建一个 TracingChannel 封装器。如果给定名称，将以 tracing:${name}:${eventType} 的形式创建相应的跟踪通道，其中 eventType 对应于 TracingChannel 通道 的类型。

¥Creates a TracingChannel wrapper for the given TracingChannel Channels. If a name is given, the corresponding tracing channels will be created in the form of tracing:${name}:${eventType} where eventType corresponds to the types of TracingChannel Channels.
