Example 1 with ExceptionLoggingChannelHandler

use of org.graylog2.inputs.transports.netty.ExceptionLoggingChannelHandler in project graylog2-server by Graylog2.

the class AbstractTcpTransport method getChildChannelHandlers.

@Override
protected LinkedHashMap<String, Callable<? extends ChannelHandler>> getChildChannelHandlers(MessageInput input) {
    final LinkedHashMap<String, Callable<? extends ChannelHandler>> handlers = new LinkedHashMap<>();
    final CodecAggregator aggregator = getAggregator();
    handlers.put("channel-registration", () -> new ChannelRegistrationHandler(childChannels));

    if (tlsEnable) {
        LOG.info("Enabled TLS for input [{}/{}]. key-file=\"{}\" cert-file=\"{}\"", input.getName(), input.getId(), tlsKeyFile, tlsCertFile);
        handlers.put("tls", getSslHandlerCallable(input));
    }

Example 2 with ExceptionLoggingChannelHandler

use of org.graylog2.inputs.transports.netty.ExceptionLoggingChannelHandler in project graylog2-server by Graylog2.

the class NettyTransport method getChannelHandlers.

/**
 * Subclasses can override this to add additional {@link ChannelHandler channel handlers} to the
 * Netty {@link ChannelPipeline} to support additional features.
 *
 * Some common use cases are to add connection counters or traffic shapers.
 *
 * @param input The {@link MessageInput} for which these channel handlers are being added
 * @return list of initial {@link ChannelHandler channel handlers} to add to the Netty {@link ChannelPipeline channel pipeline}
