hasSubscribers
true
if any of the individual channels has a subscriber, false
if not.
This is a helper method available on a {@link TracingChannel} instance to check if any of the TracingChannel Channels have subscribers. A true
is returned if any of them have at least one subscriber, a false
is returned otherwise.
const diagnostics_channel = require('node:diagnostics_channel');
const channels = diagnostics_channel.tracingChannel('my-channel');
if (channels.hasSubscribers) {
// Do something
}
