Chapter 1. Introduction to troubleshooting To troubleshoot a problem, you typically start with a symptom or set of symptoms and trace back to the cause. Troubleshooting is not the same as problem solving, although during the process of troubleshooting, you can obtain enough information to solve a problem, such as with end-user errors, application programming errors, and system programming errors. You might not always be able to solve a problem yourself after determining its cause. For example, a performance problem might be caused by a limitation of your hardware. If you are unable to solve a problem on your own, contact IBM Software Support for a solution. See Chapter 2, "Logs and data collection for troubleshooting," on page 5 for information on the types of data to collect before contacting Support. Sources of troubleshooting information The primary troubleshooting feature is logging. Logging refers to the text messages and trace data generated by the software. Messages and trace data are sent to an output destination, such as a console screen or a file. Typically, text messages relay information about the state and performance of a system or application. Messages also alert the system administrator to exceptional conditions when they occur. Consult the explanation and operator response associated with the displayed messages to determine the cause of the failure. See the document IBM Tivoli Monitoring Messages for message information. Trace data capture transient information about the current operating environment when a component or application fails to operate as designed. IBM Software Support personnel use the captured trace information to determine the source of an error or unexpected condition. See "Trace logging" on page 35 for more information about tracing. Problem classification The first task in troubleshooting is to determine the origin of the problem, or which component or function is experiencing a problem. To assist you in determining the origin of the problem, collect documentation at the time of the error. You might experience problems with IBM Tivoli Monitoring in the following areas: v Installation v Upgrading v Configuration v Connectivity v Tivoli Enterprise Portal v Tivoli Enterprise Portal Server v Tivoli Enterprise Monitoring Server v Tivoli Enterprise Monitoring Agent deployment © Copyright IBM Corp. 2005, 2012 1
