To avoid the cost of parameter construction +you can use logback's parametrized logging: +</p> + +<div class="source"><pre>x.debug("Entry number: {} is {}", i, entry[i]);</pre></div> + +<p> +This will not incur the cost of parameter construction. Compared to the +previous call to the <code>debug()</code> method, this call will be faster by +a very wide margin. +The message will be formatted only if the request is processed to the appenders. +If it is processed, the component that formats the message offers high performance +and does not impact negatively the overall process. +It respectively takes 2 and 4 microseconds to format a message with 1 and 3 parameters. +</p> + +<p> +Please notice that, despite the performance points that we just discussed, inserting +logging statements in tight-loops or very frequently invoked code is a lose-lose proposal +and will not result in high performance.

Let us now analyze the steps logback takes when the +user invokes the <code>info()</code> method of a +logger named <em>com.wombat</em>. +</p> + +<h4>1. Get the filter chain decision</h4> + +<p> +Logback's <code>TurboFilter</code> chain is called. These filters may +be used to prodvide a context-wide threshold, or to filter out certain +events based on basic logging informations such as <code>Marker</code>, +<code>Level</code>, <code>Logger</code>, message, or the <code>Throwable</code> +that was provided in the logging request. +If the reply of the filter chain is <code>FilterReply.DENY</code>, then the +logging request is dropped. If it is <code>FilterReply.NEUTRAL</code>, then +the next step is processed. In case the reply is <code>FilterReply.ACCEPT</code>, +the next step is skipped and the logging request is directly processed to step 3. +</p> + +<h4>2. Apply the Logger level filter</h4> + +<p> +Logback compares the effective level of the <em>com.wombat</em> logger +with the level of the request (in this example: <em>INFO</em>). If the logging +request is disabled, then logback will drop the request without further processing. +</p> + +<h4>3. Create a <code>LoggingEvent</code> object</h4> + +<p> +If the request passed the previous filter, or if the <code>TurboFilter</code> chain +gave a <code>FilterReply.ACCEPT</code> result, logback will create a +<code>ch.qos.logback.classic.LoggingEvent</code> object containing all the +relevant parameters of the request such as the logger of the request, the request +level, the message, the exception that might have been passed along the request, +the current time, the current thread, several information about the class that +issued the logging request and the <code>MDC</code> map. Note that some of these fields +are initialized lazily, that is only when they are actually needed. +</p> + +<h4>4. Invoking appenders</h4> + +<p> +After the creation of a <code>LoggingEvent</code> object, logback will proceed +to invoke the <code>doAppend()</code> methods of all the applicable appenders, +that is, the appenders inherited from the logger context. +</p> +<p> +All appenders shipped with the logback distribution extend the +<code>AppenderBase</code> abstract class that implements the +<code>doAppend</code> method in a synchronized block ensuring thread-safety. +The <code>doAppend()</code> method of <code>AppenderBase</code> also invokes +custom filters attached to the appender, if any such filters exist. +Custom filters, which can be dynamically attached to any appender, +are presented Chapter 6. +</p> + +<h4>5. Formatting the <code>LoggingEvent</code></h4> + +<p> +It is responsibility of the invoked appender to format the +logging event. However, most (but not all) appenders delegate +the task of formatting the logging event to their layout. Their +layout formats the <code>LoggingEvent</code> instance and returns the +result as a String. Note that some appenders, such as the +<code>SocketAppender</code>, do not transform the logging event +into a string but serialize it instead. +Consequently, they do not require nor have a layout. +</p> + +<h4>6. Sending out the <code>LoggingEvent</code></h4> + +<p> +After the logging event is fully formatted it is sent to +its destination by each appender. +</p> + + +</body> </document>
