Chapter 14 Optimizing Report Performance In This Chapter

Using Task Manager Task Manager provides information about programs and processes running on your computer. You can use Task Manager to monitor key indicators of your report server s performance. You can also assess the activity of running processes and view graphs and data on CPU and memory usage. Using Event Viewer Using Event Viewer, you can view and set logging options for event logs in order to gather information about hardware, software, and system problems. A server records events in three kinds of logs: Application log: Contains events logged by applications or programs. For example, a database program might record a file error in the application log. Application developers decide which events to log. Security log: Records events such as valid and invalid login attempts, as well as events related to resource use such as creating, opening, or deleting files or other objects. For example, if login auditing is enabled, attempts to log in to the system are recorded in the security log. System log: Contains events logged by Windows system components. For example, the failure of a driver or other system component to load during startup is recorded in the system log. The event types logged by system components are predetermined by the server. Event Viewer displays five types of events: Error: A significant problem, such as loss of data or loss of functionality. For example, if a service fails to load during startup, an Error is logged. Warning: An event that is not necessarily significant, but might indicate a possible future problem. For example, when disk space is low, a Warning might be logged. Information: An event that describes the successful operation of an application, driver, or service. For example, when a network driver loads successfully, an Information event is logged. Success Audit: Any audited security event that succeeds. For example, a user s successful attempt to log on to the system is logged as a Success Audit event. Failure Audit: Any audited security event that fails. For example, if a user tries to access a network drive and fails, the attempt is logged as a Failure Audit event. 258 Part IV: Maintaining Your Reports
