title: How can I configure Hazelcast logging
body: <p>In my Spring config file I have Hazelcast configured</p>
  
  <pre><code>&lt;!-- Hazelcast --&gt;
  &lt;hz:hazelcast id="hazelcast"&gt;
      &lt;hz:config&gt;
          &lt;hz:properties&gt;
              &lt;hz:property name="hazelcast.logging.type"&gt;slf4j&lt;/hz:property&gt;      
          &lt;/hz:properties&gt;
  
          &lt;hz:network port="$server{hazelcast.port}" port-auto-increment="false"&gt;
              &lt;hz:join&gt;
                  &lt;hz:multicast enabled="$server{hazelcast.multicast.enabled}" /&gt;
                  &lt;hz:tcp-ip enabled="$server{hazelcast.tcp-ip.enabled}"&gt;
                      &lt;hz:member&gt;appserver_1&lt;/hz:member&gt;
                      &lt;hz:member&gt;appserver_2&lt;/hz:member&gt;
                  &lt;/hz:tcp-ip&gt;
              &lt;/hz:join&gt;
          &lt;/hz:network&gt;
  
          &lt;hz:map name="aaaaaaaaaaa" /&gt;
          &lt;hz:map name="bbbbbbbbbbbbbbbb" /&gt;
  
  
          &lt;hz:map name="clientSessions"&gt;
              &lt;hz:entry-listeners&gt;
                  &lt;hz:entry-listener implementation="clientSessionListener"/&gt;
              &lt;/hz:entry-listeners&gt;
          &lt;/hz:map&gt;
  
      &lt;/hz:config&gt;
  &lt;/hz:hazelcast&gt;
  </code></pre>

  <p>Answer (unable to answer as yet !)</p>
  
  <p>In the file log4j.xml</p>
  
  <p>I added this:   </p>
  
  <pre><code>&lt;logger name="com.hazelcast"&gt;
      &lt;level value="debug" /&gt;
  &lt;/logger&gt;
  </code></pre>
