Table 5-26 Log and trace output by the in-process HTTP server

Types of log and trace	Description
Access log	Outputs the result of request and response processing from the Web client. This log is used for analyzing the communication with the Web client. By analyzing the access log, you can analyze the files requested from the Web client and the performance information and session tracking information of the in-process HTTP server.
Performance analysis trace	Outputs the performance analysis information of the sending and receiving of requests and the information for troubleshooting in the case of failure in the in-process HTTP server. The performance analysis trace is converted to a CSV format and can be used to analyze the bottlenecks in the entire system in combination with the performance analysis information output by the functionality of other J2EE servers. For details on the performance analysis trace, see 4.6 Performance analysis trace in the uCosminexus Application Server Maintenance and Migration Guide.
Thread trace	Trace for maintenance.
Communication trace	Trace for maintenance.
