Agent ConfigurationAbout this section...This section has information about agent configuration data - how it is initially supplied,where it is saved, and how to change it.For information about where agent configuration fits into the vFabric Hyperic deploymentprocess, see:Step 4 - Set Up the vFabric Hyperic Agent on the vFabric Hyperic Installation and StartupProcess page — for new vFabric Hyperic installationsvFabric Hyperic Upgrade Processes — for upgrade installationsAgent Startup Configuration DataThe configuration choices you must supply for the agent to start up specify where and how itcommunicates with the vFabric Hyperic Server, and vice versa. You can supply these setupvalues either interactively at first startup, or in the agent's agent.properties file before firststartup. For a list of setup properties and definitions, see Communication Properties Reference.After the agent and server establish successful communication upon first agent startup:The vFabric Hyperic Agent saves the server's connection data in AgentHome/data.The agent creates the /data directory upon first successful startup. On subsequentstartups, the agent will look at the connection data stored in its /data directory todetermine where and how to connect to the vFabric Hyperic Server.The vFabric Hyperic Server stores the agent's connection data in the vFabric Hypericdatabase.Optional Agent Configuration PropertiesAs described above in Agent Startup Configuration Data, at first successful startup, the agentsaves the server connection data in its /data directory, and upon subsequent startups, looksthere for the server connection data. If agent finds the server connection data in its /datadirectory, it does not look at agent.properties for the connection data.Other agent properties that configure optional features and behaviors are persisted only inagent.properties. For a complete list of agent properties, see Agent Properties.Supported Locations for agent.propertiesagent.properties is installed in AgentHome/conf.Note however, that the agent first honors an external (from the agent installation) location for theproperties file: an .hq directory under the home directory of the user under which the agentruns. The agent honors this location for agent.properties so that if you upgrade an agentby installing a full agent package (rather than just updating the agent bundle), you will not losethe configuration settings defined in agent.properties.12
You can also ensure that you do not lose agent configuration settings by backing upAgent/conf/agent.properties before installing a full package, and restoring the file afterinstallation.You can upgrade a 4.x agent by installing an agent bundle only - you can perform this upgradeoperation from the vFabric Hyperic user interface or using a manual procedure. When youupgrade the agent bundle only, the agent's /conf directory is not updated — this methodpreserves the agent.properties file within the agent installation through the upgrade.How to Change Agent Setup Configuration PropertiesYou configure an agent's setup properties either interactively at first startup, or inagent.properties prior to first startup The properties that relate to where and how to contactthe vFabric Hyperic server, are saved in the agent's /data directory; those related to howthe server can reach the agent are stored in the vFabric Hyperic database.If you need to make changes to those configuration values for an agent at a later time, you candelete the agent's /data directory, edit the agent.setup.* properties in theagent.properties file, and restart the agent. You must use this method if you wish tochange the agent's listen port — you cannot change port settings without restarting the agent.If you prefer to change the startup configuration (other than agent listen port) without having torestart the agent, run the following command in a command shell, while the agent is running.AgentHome/hq-agent.sh setupThis will allow you to interactively supply new values for the setup properties, as described inSet Up Agent Interactively. This will this cause all properties in the properties file to be re-read,and take effect.Agent Launcher and Agent StartupAbout this section...This page describes the vFabric Hyperic Agent launcher and the agent startup process.For information about:Starting an agent — See Start, Stop, and Other Agent OperationsSSL certificate verification — See About SSL in vFabric HypericAgent LauncherThe vFabric Hyperic Agent launcher is based on the Java Service Wrapper (JSW), aconfigurable tool that allows Java applications to be run as an NT service or Unix daemonprocess. It includes fault correction software to automatically restart crashed or frozen JVMs.13
