使用 percona cacti 监控 tomcat

Question

我正在尝试使用 percona cacti 图表监视 tomcat 应用程序。该应用程序使用来自 windows 的 jconsole 工作。主机是centos 6.6 64位，我已经安装了ant。

当我尝试运行 percona 给出的示例时，它对我不起作用。

我注意到我必须从 jmx-monitor.xml 中删除以下内容才能使其正常工作。

            <jmx:get
                    name="Catalina:type=ThreadPool,name=${jmx.catalina.threadpool.name}"
                    attribute="currentThreadsBusy"
                    resultproperty="currentThreadsBusy"
                    />
            <jmx:get
                    name="Catalina:type=ThreadPool,name=${jmx.catalina.threadpool.name}"
                    attribute="currentThreadCount"
                    resultproperty="currentThreadCount"
                    />
            <jmx:get
                    name="Catalina:type=ThreadPool,name=${jmx.catalina.threadpool.name}"
                    attribute="maxThreads"
                    resultproperty="maxThreads"
                    />
current_threads_busy: ${currentThreadsBusy}
current_thread_count: ${currentThreadCount}
max_threads: ${maxThreads}

如果不删除上述内容，我将如何让它工作。以下命令是运行 by cati

ant -Djmx.server.port=9012 -Djmx.catalina.threadpool.name=http-8080 -e -q -f jmx-monitor.xml

Answer 1

根据您的工作，我刚刚将以下行添加到 jmx-monitor.xml。

<property name="jmx.catalina.threadpool.name" value="http-8080" />

而且有效。

ant -Djmx.server.port=12345 -e -q -f jmx-monitor.xml -v

或者通过以下命令测试即可。（我认为 docs 在 http://www.percona.com/doc/percona-monitoring-plugins/1.1/cacti/jmx-templates.html 中不好）

ant -Djmx.server.port=9012 -e -q -f jmx-monitor.xml -Djmx.catalina.threadpool.name=http-8080
