Chapter 12. Monitor Red Hat JBoss Data Grid Applications in Red Hat JBoss EAP

Monitor JBoss Data Grid Applications in JBoss Enterprise Application Platform

1. Configure RHQ/JBoss Operations Network

   Add an RHQ/JBoss Operations Network specific property (named org.rhq.resourceKey) to the /bin/[path]standalone.conf file as follows:

   JAVA_OPTS="$JAVA_OPTS -Dorg.rhq.resourceKey=MyEAP"

   Copy to Clipboard Toggle word wrap

   This command adds the property to the JBoss Enterprise Application Platform’s command line indirectly.

2. Check RHQ/JBoss Operations Network is Running Using a Full JDK

   Ensure that the RHQ/JBoss Operations Network agent started using a full JDK instead of a JRE. This is because the agent requires access to the JDK’s tools.jar file.

   To configure your RHQ/JBoss Operations Network agent to use the JDK, follow the instructions relevant to your operating system:

   1. For Linux users, set the RHQ_AGENT_JAVA_HOME environment variable to the JDK home directory in the agent’s rhq-agent-env.sh file.
   2. For Windows users, set the RHQ_AGENT_JAVA_HOME environment variable to the JDK home directory in the agent’s rhq-agent-env.bat file.

3. Ensure the Agent is Local to the JBoss Enterprise Application Platform Instance

   Ensure that the RHQ/JBoss Operations Network agent runs locally to and under the same user as the JBoss Application Platform instance. This is required for the Java Attach API to connect to the process.

4. Import Resources to the Agent Inventory

   RHQ/JBoss Operations Network can now discover resources. These resources can subsequently be imported into the agent inventory.

   When a JBoss Data Grid user deployment enables JMX statistics to expose JBoss Data Grid Cache Managers or caches, the resources appear as children resources of the JBoss Enterprise Application Platform instance.
