This section covers the configuration, files, and options for the JBoss Operations Network server and agents.
2.1. JBoss ON File Locations

This section covers the common files and directories by JBoss ON servers and agents. A basic reference for these files can make managing and troubleshooting JBoss ON easier.
2.1.1. JBoss ON Server File Locations
复制链接链接已复制到粘贴板!
All JBoss Operations Network servers are installed in a single, user-defined server root directory. In the documentation and examples, this is called serverRoot. The directory layout within that server root directory are the same for every server.

The directories and files that are most commonly used to managed JBoss ON servers are listed in Table 1, “JBoss ON Server Directories and Files”. The server root varies for each installation and each platform, but the layout of the JBoss ON subdirectories is the same for every platform.
| Configuration Area | Directory or File Location | Description |
|---|---|---|
| Configuration directory | serverRoot/bin/ | Contains the server start scripts, PID files, and configuration file. |
| Start scripts | serverRoot/bin/rhq-server{.sh|.bat} | The script to start, stop, and check the status of the server. |
| Configuration file | serverRoot/bin/rhq-server.properties | The configuration file for all server settings that are not stored in the JBoss ON database. |
| Password hash script | serverRoot/bin/generate-db-password{.sh|.bat} | For a migrated server, it generates an encoded form of the database password to use in the rhq-server.properties file. |
| SNMP files | serverRoot/etc/RHQ-mib.txt | The JBoss ON MIB file to use for setting SNMP traps. |
| Log files | serverRoot/logs/ | The JBoss ON server log files are automatically created in this directory. The current log is named rhq-server-log4j.log. Older log files are named rhq-server-log4j.log.#, and the higher the number, the older the log file. |
| Custom plug-in deployment directory | serverRoot/plugins/ | The directory where custom plug-in files can be dropped for them to be automatically detected and polled by the JBoss ON server. |
| JBoss AS directory | serverRoot/jbossas/ | Contains all of the required JBoss AS client and server libraries.[a] |
| Server JAR files | serverRoot/jbossas/default/deploy/rhq.ear/ | Contains all of the JAR files used by JBoss ON servers, web interface, and clients. |
| Server-side plug-ins directory | serverRoot/jbossas/default/deploy/rhq.ear/rhq-serverplugins/ | Contains all of the JAR files for the default JBoss ON server-side plug-ins. |
| Agent plug-ins directory | serverRoot/jbossas/default/deploy/rhq.ear/rhq-downloads/rhq-plugins/ | Contains all of the JAR files for the default JBoss ON agent plug-ins. |
| Server-side plug-ins directory | serverRoot/jbossas/default/deploy/rhq.ear/rhq-serverplugins/ | Contains all of the JAR files for the default JBoss ON server-side plug-ins. |
| Agent package directory | serverRoot/jbossas/default/deploy/rhq.ear/rhq-downloads/rhq-agent/ | Contains the snapshot packages for the JBoss ON agent. |
| Web interface directory | serverRoot/jbossas/default/work/jboss.web/localhost/ | Contains the directories that hold the files for rendering the web interface. |

Most of the libraries and files in this directory don't relate directly to JBoss ON.

2.1.2. JBoss ON Agent File Locations

Like the server, the JBoss ON agent is installed in a single, user-defined root directory. All of the agent files and directories are under the
rhq-agent/ directory in that root directory.

bin/ conf/ data/ lib/ logs/ plugins/| Configuration Area | Directory or File Location | Description |
|---|---|---|
| Start scripts | serverRoot/rhq-agent/bin/ | Contains the agent start scripts. |
| Configuration file | serverRoot/rhq-agent/conf/agent-configuration.xml | The configuration file for basic agent settings. |
| Library files | serverRoot/rhq-agent/lib/ | Contains the libraries used by the agent to monitor resources. |
| Start scripts | serverRoot/rhq-agent/logs/ | The JBoss ON agent log files are automatically created in this directory. The current log is named agent.log. Older log files are named agent.log.#, and the higher the number, the older the log file. |
| Plug-ins directory | serverRoot/rhq-agent/plugins/ | Contains the plug-ins used by the agent for managing resources (like editing resource configuration). |
