Jetty监控线程使用情况的配置
Jetty监控线程使用情况配置
第一步,配置xml文件
jetty-monitor.xml
参数说明:
threads: 线程池中的线程
busyThreads: 使用中的线程
idleThreads: 空闲的线程
lowOnThreads: 是否达到maxThread并且没有空闲线程接受请求(True if the pools is at maxThreads and there are not idle threads than queued jobs)
queueSize: 排队中的job数

jetty-jmx.xml(保持原样不动即可,以下为参考)
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure_9_3.dtd">
<Configure id="Server" class="org.eclipse.jetty.server.Server">
<!-- =========================================================== -->
<!-- Get the platform mbean server -->
<!-- =========================================================== -->
<Call id="MBeanServer" class="java.lang.management.ManagementFactory"
name="getPlatformMBeanServer" />
<!-- =========================================================== -->
<!-- Initialize the Jetty MBean container -->
<!-- =========================================================== -->
<Call name="addBean">
<Arg>
<New id="MBeanContainer" class="org.eclipse.jetty.jmx.MBeanContainer">
<Arg>
<Ref refid="MBeanServer" />
</Arg>
</New>
</Arg>
</Call>
<!-- Add the static log -->
<Call name="addBean">
<Arg>
<New class="org.eclipse.jetty.util.log.Log" />
</Arg>
</Call>
</Configure>
第二步,导入xml文件
在jetty.conf中添加以下行:
jetty-monitor.xml
jetty-jmx.xml
第三步,开启对应模块
在start.ini中添加以下行:
--module=monitor
--module=jmx
第四步,重启jetty容器
线程的使用情况会以log的形式展现出来:
