C Server Log File Formats
This appendix describes the formats used in the log files generated by the iTP Secure
WebServer:
•
Access Log Format on page C-1
•
Error Log Format on page C-3
•
HyperText Transfer Protocol (HTTP) Status Codes on page C-3
•
Extended Log Format on page C-4
An entry in these files is structured into a set of distinct components. These
components vary by file type.
Some products and components you use with the iTP Secure WebServer can report
configuration, status, and error messages to other files you specify. For example, the
Servlet Server Class (SSC) reports configuration and status information to the
standard output file, and reports error and exception information to the standard error
file. For information about reporting by the SSC, see Section 9, Using NonStop
Servlets for JavaServer Pages (NSJSP).
Access Log Format
The access log file records the request history of a server. The information in this file is
structured in the common log format (CLF). CLF is used by other web servers and
supports a number of widely available tools for analyzing logs and generating reports.
The location of the access log file is specified by the AccessLog directive in the server
configuration file. If this directive is not explicitly set, no access log file is generated.
Access Log Entry Format
An entry in the access log file consists of a single line of ASCII text. Each entry logs a
single client request and consists of seven fields of information:
Field 1 host-name
Field 2 -
Field 3 user-name
Field 4 time
Field 5 request
Field 6 http-status
Field 7 bytes-sent
