+    <p>This example illustrates how to configure your YUI instance to ignore certain log messages to aid in reducing the signal-to-noise ratio when debugging.</p>
+
+    <p>Log messages filtered out from the YUI config are permanently ignored.  If you want to be able to temporarily hide and reshow messages, use the <a href="../console-filters/">ConsoleFilters plugin</a>.  It is not uncommon to set up <code>logInclude</code> or <code>logExclude</code> in the YUI configuration and use the ConsoleFilters plugin.</p>
+
+    <p>Log messages can be ignored based on the source (e.g. <code>event</code> or <code>attribute</code>) or based on their log level (info, warn, error).</p>

+<h3>Setting up filters in the YUI configuration</h3>
+<p>The configuration object passed to the YUI constructor supports a few settings that can help manage Console output while debugging.  These configuration options are <code>logExclude</code>, <code>logInclude</code>, <code>logLevel</code>, <code>filter</code>, and <code>filters</code>.</p>
+
+<p>This example will show the use of the <code>logInclude</code>, <code>logExclude</code>, and <code>logLevel</code> configurations.</p>
+
+<p>An example configuration might look like this:</p>
+
+<pre class="code prettyprint">YUI({
+    filter : &#x27;debug&#x27;, &#x2F;&#x2F; request -debug versions of modules for log statements
+    logExclude : {
+        event : true,     &#x2F;&#x2F; Don&#x27;t broadcast log messages from the event module
+        attribute : true, &#x2F;&#x2F; or the attribute module
+        widget : true     &#x2F;&#x2F; or the widget module
+    },
+    logLevel : &#x27;error&#x27;,       &#x2F;&#x2F; Show only errors in the Console
+    useBrowserConsole : false &#x2F;&#x2F; Don&#x27;t use the browser&#x27;s native console
+}).use(&#x27;overlay&#x27;,&#x27;anim&#x27;,&#x27;console&#x27;, function (Y) {
+
+&#x2F;* Console instances will default to logLevel = &quot;info&quot; *&#x2F;
+
+});</pre>
+
+
+<p><code>logExclude</code> and <code>logInclude</code> prevent the logging subsystem from broadcasting filtered log messages.  <code>logLevel</code>, on the other hand is used by Console instances to filter messages received from the subsystem.</p>
+
+<p>Updating <code>Y.config.logExclude</code> or <code>Y.config.logInclude</code> at runtime will immediately change the subsystem filtering, but will not recover messages previously sent from that source.</p>
+
+<pre class="code prettyprint">YUI({
+    logExclude : {
+        event : true
+    }
+}).use(&#x27;console&#x27;, function (Y) {
+
+&#x2F;* In here, Y.config refers to the config object passed to the constructor *&#x2F;
+
+&#x2F;&#x2F; Stop broadcasting log messages from the attribute module
+Y.config.logExclude.attribute = true;
+
+&#x2F;&#x2F; Start broadcasting log messages from the event module again
+delete Y.config.logExclude.event;
+
+});</pre>
+
+
+<p>When a Console is instantiated, barring explicit <code>logLevel</code> attribute configuration, the <code>logLevel</code> will be adopted from the YUI instance's configured <code>logLevel</code>, or <code>Y.Console.LOG_LEVEL_INFO</code> (&quot;info&quot;) as a fallback.  Unlike <code>logExclude</code>, changing the value in the YUI configuration will only affect instantiated Consoles from that point on.  Additionally, you can manually override the <code>logLevel</code> a Console instance will display by updating its <code>logLevel</code> attribute.</p>
+
+<pre class="code prettyprint">YUI({ logLevel : &quot;warn&quot; }).use(&#x27;console&#x27;, function (Y) {
+
+var yconsole_1 = new Y.Console(); &#x2F;&#x2F; logLevel == &quot;warn&quot;
+
+var yconsole_2 = new Y.Console({
+    logLevel : &quot;info&quot; &#x2F;&#x2F; override at construction
+});
+
+&#x2F;&#x2F; This will not affect yconsole_1 or yconsole_2
+Y.config.logLevel = &quot;error&quot;;
+
+var yconsole_3 = new Y.Console(); &#x2F;&#x2F; logLevel == &quot;error&quot;
+
+yconsole_1.set(&quot;logLevel&quot;, &quot;info&quot;); &#x2F;&#x2F; update this instance
+
+});</pre>
+
+
+<p>The interactive portion of this example illustrates the effect of various filter settings against logged messages.  In a real application, it is most likely that the logging configuration won't be changed at runtime but set once in the YUI configuration at construction.</p>
+
+<p>The most relevant portion of the <a href="#full_code_listing">code for the demo above</a> is the updating of the YUI config and Console attribute.</p>
+
+<pre class="code prettyprint">&#x2F;&#x2F; Create and render the Console
+var yconsole = new Y.Console({
+    boundingBox: &#x27;#console&#x27;, &#x2F;&#x2F; anchored to the page for the demo
+    style: &quot;block&quot;
+}).render();

+Y.on(&quot;change&quot;, function () {

+        delete Y.config.logExclude;

+        delete Y.config.logInclude;

+    updatePreview();
