IBM HTTP Server LogsIBM HTTP Server Logs
2 logs from HTTP Server:
access.log
• Provides HTTP request information
• Returns responses by Web server

- 5. 5/82 Log File: Level of OutputLog File: Level of Output • Output information needed • Adjust level of output in logging property file Audit (default): Record all messages Error: Report severity errors Warning: Warning indicate a problem occurred and should be corrected. Report both severity errors or warnings
- 6. 6/82 Installation LogsInstallation Logs wssetup.log • Created during processing of setup.exe • Hardware configuration • Software prerequisites present • Configuration of the Administrative Server wasdb2.log • Record the process of creation and configuration of Administrative database
- 7. 7/82 Administrative Server LogsAdministrative Server Logs 3 logs to monitor progress and errors: • _adminserverFatalError.log Serious error log • Tracefile Logs the startup and shutdown of the Administrative Server • Adminserver-stderr.log Record error during start up
- 8. 8/82 Application Server LogsApplication Server Logs default_server_stdout.log • Indicates failures within the Java components under Application Server • Contains exceptions thrown by the applications running under the default_server

- 11. 11/82 Plug-in LogsPlug-in Logs native.log • Contains error and informational messages generated by the Web server plug-in • Shows information about the startup and changes applied to the server
- 12. 12/82 Log AnalyzerLog Analyzer • Reads error conditions in the Activity log • Analyze error conditions to provide error message explanations and, error message recovery instructions • Takes one or more activity logs merges all the data, & displays
- 13. 13/82 TracesTraces • Same as Logs, but needs to be enabled • Gets additional information from IBM code base • Get operational aspects of Websphere • Options can be chosen on what to trace • If enabled, a huge system overhead generated

- 15. 15/82 Resource AnalyzerResource Analyzer • Use to retrieve performance data from application servers • Data is collected continuously Resource Analyzer can accomplish: • View performance data in real time • Record performance information into log file • Monitor and estimate the load on application servers & the average wait time for clients • View historical performance data from the log file • View information captured in a chart • Perform a comparison evaluation for a single resource to a group of resources on a single node
- 16. 16/82 Resource AnalyzerResource Analyzer Represents a physical machine Represents a server provides functionality over network manipulate the raw data that is collected about the application server. Data type to hold performance data Represents one or more resource categories Eg. (EJB) Manipulate raw data that is collected about the application server.
- 17. 17/82 Resource Analyzer (con’t)Resource Analyzer (con’t) It can collect and report performance on: • Java runtime • Database connection pools • EJBs • EJB methods • Enterprise bean object pools • Transactions • Web Applications
