Log Context

Log ”Using [{}] as transport; overridden by [{}]” classname is TransportModule.java
We have extracted the following from Elasticsearch source code to get an in-depth context :

<pre class="wp-block-syntaxhighlighter-code">             }
        }

        bind(NamedWriteableRegistry.class).toInstance(namedWriteableRegistry);
        if (configuredTransport != null) {
            logger.info("Using [{}] as transport; overridden by [{}]"; configuredTransport.getName(); configuredTransportSource);
            bind(Transport.class).to(configuredTransport).asEagerSingleton();
        } else {
            String defaultType = DiscoveryNode.localNode(settings) ? LOCAL_TRANSPORT : NETTY_TRANSPORT;
            String typeName = settings.get(TRANSPORT_TYPE_KEY; defaultType);
            Class<? extends Transport> clazz = transports.get(typeName);
