Troubleshooting MCollective

The ulimit must be adequate for the number of files (nofile) and number of processes (nproc) handled in your environment.

pe-activemq   soft     nproc  8192
pe-activemq   hard     nproc  8192
pe-activemq   soft     nofile 16384
pe-activemq   hard     nofile 16384

The ActiveMQ service provides a console that can be used for advanced debugging, such as pulling performance metrics from the AMQ service while it's running. The console must be configured for access.

1. On the Puppet master, edit /etc/puppetlabs/activemq/jetty.xml so that the "host" value of the "connectors" property is set to `"0.0.0.0". For example:

   <bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start">
   <!-- the default port number for the web console -->
   <property name="host" value="0.0.0.0"/>
   <property name="port" value="8161"/>
   </bean>
   

2. In the console, click Classification, and in the PE Infrastructure node group, select the PE ActiveMQ Broker node group.
3. On the Configuration tab, under the puppet_enterprise::profile::amq::broker class, set the enable_web_console parameter to true.
4. Click Add parameter and commit changes.
5. Run Puppet on the agents in the PE ActiveMQ Broker group.
