用druid做数据源, 怎么监控session啊

[我是全栈架构师]

用druid做数据源, 怎么监控session啊
配置如下:

<init-param>
<param-name>principalSessionName</param-name>
<param-value>xxxxxxxxx</param-value>
</init-param>

点session监控, 里面都是空的;
上面xxxxxxxxx部分, 应该写什么啊,
请教高手

配置如下过滤器

<filter>
	    <filter-name>DruidWebStatFilter</filter-name>
	    <filter-class>com.alibaba.druid.support.http.WebStatFilter</filter-class>
	    <init-param>
	        <param-name>exclusions</param-name>
	        <param-value>*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*</param-value>
	    </init-param>
	    <init-param>
	        <param-name>profileEnable</param-name>
	        <param-value>true</param-value>
	    </init-param>
	    <init-param>
	        <param-name>principalCookieName</param-name>
	        <param-value>USER_COOKIE</param-value>
	    </init-param>
	    <init-param>
	        <param-name>principalSessionName</param-name>
	        <param-value>USER_SESSION</param-value>

按你说的配上了，可是不能生效，别的监控都有了，session监控没数据，出不来，怎么整？
