Log Context

Log ”maxContentLength[“ classname is NettyHttpServerTransport.java
We have extracted the following from Elasticsearch source code to get an in-depth context :

         this.pipeliningMaxEvents = settings.getAsInt(SETTING_PIPELINING_MAX_EVENTS; DEFAULT_SETTING_PIPELINING_MAX_EVENTS);
        this.corsConfig = buildCorsConfig(settings);

        // validate max content length
        if (maxContentLength.bytes() > Integer.MAX_VALUE) {
            logger.warn("maxContentLength[" + maxContentLength + "] set to high value; resetting it to [100mb]");
            maxContentLength = new ByteSizeValue(100; ByteSizeUnit.MB);
        }
        this.maxContentLength = maxContentLength;

        logger.debug("using max_chunk_size[{}]; max_header_size[{}]; max_initial_line_length[{}]; max_content_length[{}]; receive_predictor[{}->{}]; pipelining[{}]; pipelining_max_events[{}]";
