Utilities Primitives for Substrate
Features
metered
This feature changes the behaviour of the function mpsc::tracing_unbounded
.
With the disabled feature this function is an alias to futures::channel::mpsc::unbounded
.
However, when the feature is enabled it creates wrapper types to UnboundedSender<T>
and UnboundedReceiver<T>
to register every send
/received
/dropped
action happened on
the channel.
Also this feature creates and registers a prometheus vector with name unbounded_channel_len
and labels:
Label | Description |
---|---|
entity | Name of channel passed to tracing_unbounded |
action | One of send /received /dropped |
