Info

o By default, the run-time scan runs once a day. You can configure the frequencyusing the autoinventory.runtimeScan.interval.millis inagent.properties.Server-to-Agent CommunicationUnless a vFabric Hyperic Agent is configured for unidirectional communication, the vFabricHyperic Server initiates communication with a vFabric Hyperic Agent to provide metric collectionschedules, and relay the commands and data issued or configured by authorized users.Server-to-agent traffic is always over SSL, and includes:SSL certificate — When the vFabric Hyperic Server connects to an agent using https, itpresents an SSL certificate as part of the handshake. For information about certificateverification, see vFabric Hyperic 4.6.x SSL Certificate Processing on About SSL invFabric Hyperic.metric collection schedulesresource control actionsrequests to initiate auto-inventory scansplugin updates — If, during the SAPS process, the vFabric Hyperic Server detects pluginmismatches between the product plugins on the server and those deployed an agent,the server syncs the agent's plugin population to resolve the mismatches, and restartsthe agent. This behavior is described in About Plugin Sync at Server Startup on PluginDeployment and Management in vFabric Hyperic Administration.Unidirectional Agent-Server CommunicationsThe default communication between an agent and the server is bi-directional — the vFabricHyperic Agent establishes a connection with the vFabric Hyperic Server to send the datadescribed in Agent-to-Server Communication, and the vFabric Hyperic Server establishes aconnection with the vFabric Hyperic Agent to send the data described in Server-to-AgentCommunication.If your security policies dictate, you can configure the agent to initiate all communications withthe vFabric Hyperic Server. You can configure unidirectional communications interactively, atfirst agent startup, or in an agent's AgentHome/conf/agent.properties file. If you want tochange from bidirectional to unidirectional communications after initial agent configuration, seeConfigure Unidirectional Agent - Server Communication.If an agent is configured for unidirectional communication, the vFabric Hyperic Server does notestablish a connection to the agent. Instead, at startup, the agent establishes a persistentconnection to the vFabric Hyperic Server, and polls the server periodically for servercommunication.16
Unidirectional Communication via a ProxyIf you use unidirectional communications, you can configure the vFabric Hyperic Agent tocommunicate with the vFabric Hyperic Server via a proxy server. You must configure thisbehavior in each agent's agent.properties file. For more information, see Set Up Agent inProperties File.Agent Directory StructureThe structure of the vFabric Hyperic Agent installation directory is shown below.agent-4.6.nbinbundlesagent-4.x.y-nnnnconfdatalogwrapperThe root of the directory structure shown above as agent-4.x.y is typically referred to invFabric Hyperic documentation as the AgentHome directory. Key agent directories include:AgentHome/bin - contains agent start scripts: hq-agent.sh and hq-agent.batAgentHome/conf - contains agent.propertiesAgentHome/data - this is the directory where the agent saves the connectionproperties it uses to contact the vFabric Hyperic Server.AgentHome/log - contains:o agent.logo agent.startup.logo wrapper.logSizing Profiles in vFabric HypericAbout this section...This page describes how the vFabric Hyperic installer in vFabric Hyperic 4.6.5 and latersets the values of key server properties that affect the system resources allocated to serverprocessing.17
