Info

Depending on your environment, you may find it useful to track other agent metrics, such as:In addition to the default metricsNumber of Metrics which Failed to be CollectedNumber of Metrics which Failed to be Collected per MinuteMaximum Time Spent Processing a RequestNumber of Connection FailuresTotal Time Spent Fetching Metrics per MinuteFor more information about default and available agent metrics see View vFabric Hyperic AgentMetrics.Log FilesThe following log files can be a useful source of information in the event that a problem occursin a vFabric Hyperic deployment:ServerHome/logs/wrapper.logServerHome/logs/bootstrap.logServerHome/logs/server.logServerHome/logs/hqdb.log (only available for deployments usingthe built-in PostgreSQL database.AgentHome/logs/wrapper.logAgentHome/logs/agent.logAgentHome/logs/agent.log.startupYou can increase the level of logging an agent performs in its agent.properties file. Notethat debug logging is very verbose and uses more system resources. vFabric Hypericrecommends configuring debug logging only when troubleshooting problems, and only at thesubsystem level. For more information, see Configure Agent Logging.Thread DumpsThis section has instructions for generating thread dumps for the vFabric Hyperic Server andvFabric Hyperic Agent.Generate a vFabric Hyperic Server Thread Dump from User InterfaceFollow these steps to output a server thread dump to your browser.1. Click the Administration tab.2. Click HQ Health in the Plugins section of the Administration page.3. Click Print in the HQ Process Information section on the HQ Health page.104
Generate a vFabric Hyperic Server Thread Dump from Command LineTo generate a thread dump on Windows:If vFabric Hyperic Server is running in a terminal window — Try in theterminal window.If vFabric Hyperic Server is running as a service — Use a tool like StackTrace.To generate a thread dump on Unix-like systems, use jstackhttp://download.oracle.com/javase/1.5.0/docs/tooldocs/share/jstack.html on the vFabric HypericServer process. For example, if the server's PID is 215:jstack 215 >mydumpfile.txtHow to find the vFabric Hyperic Server PIDYou can run jps in a shell to determine the vFabric Hyperic Server's process ID — look forthe process named "Bootstrap". For example:$ jps187 WrapperStartStopApp408 Jps215 BootstrapOn Unix-like systems, you can also run Kill -3 on the vFabric Hyperic server process.Note however, that if you do, the thread dump will be written to wrapper.log, and bedifficult to parse.Generate Agent Thread Dump from User InterfaceRun the agent launcher with the dump option. For more information see Start, Stop, and OtherAgent Operations.Check Port AvailabilityThe vFabric Hyperic Server must be able to establish a connection with the agent, and viceversa.To verify that the server can access the agent's listen port, run the following from the serverplatform:telnet AgentIp AgentPort105
