tomcat - ant 无法检索 RMIServer stub NameNotFoundException jmxrmi

Question

我安装了 alfresco 4.0d，我正在尝试使用 cacti 设置监控。我从percona得到了模板.当我尝试运行以下命令时出现错误。我使用了 tomcat/lib 目录中 percona 链接中提到的 jar 文件。

更新

一旦设置了所需的值，我就可以在 64 位 Windows 上使用 jconsole 进行监控。

### RMI service ports ###
alfresco.rmi.services.port=50500
monitor.rmi.service.port=50508
alfresco.rmi.services.external.host=172.16.0.49

在 ctl.sh - -Dcom.sun.management.jmxremote=true -Djava.rmi.server.hostname=172.16.0.36

我的 Cacti 服务器是 172.16.0.15，我的带有 jconsole 的 64 位 Windows 是 172.16.0.49，我的露天服务器是 172.16.0.36。如果我可以用 jconsole 做到这一点，我该如何用 cacti 进行监控？

当我运行 ant -e -q -f jmx-monitor.xml 时，我得到以下信息

BUILD FAILED
/home/cacti/jmx-monitor.xml:22: Problem: failed to create task or type antlib:org.apache.catalina.ant.jmx:open
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet

This appears to be an antlib declaration. 
Action: Check that the implementing library exists in one of:
        -/usr/share/ant/lib
        -/root/.ant/lib
        -a directory added on the command line with the -lib argument

我试过使用端口 9012、50500、50508

在 jconsole 上，我使用以下命令 service:jmx:rmi:///jndi/rmi://172.16.0.36:50500/alfresco/jmxrmi 并使用 >webapps/alfresco/WEB-INF/classes/alfresco/alfresco-jmxrmi.*

我更新了 setenv.sh 并添加了

CATALINA_OPTS="-Dcom.sun.management.jmxremote
  -Dcom.sun.management.jmxremote.port=%9012%
  -Dcom.sun.management.jmxremote.ssl=false
  -Dcom.sun.management.jmxremote.authenticate=false"
export CATALINA_OPTS

我可以使用 jconsole url 监控 tomcat:service:jmx:rmi:///jndi/rmi://172.16.0.36:9012/jmxrmi

Answer 1

JMX 在 Alfresco Community Edition 中不可用。
