[GO] How to configure and use the Tomcat access log

Configure the location under Log for Server.xml, (Tomcat container)

Access log valve is used to create a log file in the same format as a standard Web server log file. Logs can be analyzed using the log Analysis tool to track page clicks, user session activity, and so on. Many of the configuration and behavior characteristics of Access log valve are the same as file logger, including automatic switching of log files nightly at midnight. Access log valve can be associated with any Catalina container and records all requests processed by that container.
Examples are as follows:

directory= "Logs" prefix= "Localhost_access_log." suffix= ". txt"
pattern= "%{x-forwarded-for-pound}i%l%u%t"%r "%s%b%t"%{http_x_up_calling_line_id}i ""%{x-up-calling-line-id}i ""%{ User-agent}i "" resolvehosts= "false"/>

ClassName	The Java class name of the implementation. Must be set to Org.apache.catalina.valves.AccessLogValve.
Directory	The directory where the log files are stored, either relative or absolute paths. If a relative path is used, it refers to the path relative to the $CATALINA _home. If you do not specify a directory property, the default value is "Logs" (relative to $CATALINA _home)
Pattern	The format layout of the different information fields needs to be recorded for the request/response. If it is "common" or "combine", the standard format is selected. More information on configuring this property is available below.
Prefix	The prefix of the log file name. If not specified, the default value is "Access_log." If you do not want to use a prefix, use a string of length 0.
Resolvehosts	Set the IP address of the remote host to true by converting the DNS query to the host name. If False, the DNS query is ignored, and the IP address of the remote is reported.
Suffix	The suffix of the log file name. If not specified, the default value is "". If you do not want to use a suffix, use a string of length 0.
Rotatable	The default value is True, which is used to determine whether the log is flipped. If False, the log file is never flipped, and Filedataformat is ignored. Use sparingly.
Condition	Open the condition log. If this property is set, the log will be created for the request only if Servletrequest.getattribute () is null. For example, if condition is set to junk, the request will only be logged if the Servlet.getattribute ("junk") ==null. With filters, you can easily set (or de-set) the properties of different requests.
Filedateformat	Allows you to use a custom date format in the log file name. The format of the log also determines how often the log file is flipped. If you want to flip once every hour, set this value to Yyyy-mm-dd.hh

The Pattern property value is combined with the prefix "%" of the string constant and the pattern identifier. The pattern identifier is prefixed with "%" to replace the corresponding variable value in the current request/response. The following pattern is currently supported:

• %a -Remote IP address
• %A -Local IP address
• %b -Number of bytes sent, excluding HTTP headers, if 0, use "-"
• %B -Number of bytes sent, not including HTTP headers
• %h -Remote host name (if resolvehost=false, remote IP address)
• %H -Request Agreement
• %l -The remote logical user name returned from Identd (Always return '-')
• %m -Method of request (Get,post, etc.)
• %p -Local port number to which the request was received
• %q -query string (if present, to '? ') Start
• %r -The first line of the request, containing the requested method and URI
• %s -Status code of the response
• %s -session ID of the user
• %t -Log and time, using the usual log format
• %u -remote user after authentication (if present, otherwise '-')
• %u -URI path of the request
• %v -Name of the local server
• %d -the time, in milliseconds, to process the request
• %T -the time, in seconds, to process the request

Examples of the results are as follows:
---[29/aug/2005:09:34:48 +0800] "get/waptest/server?productid=qqportal&actionid=index&user_type=1& Station=tencent&mid=12345678908888&mobile_no=13724179457&qazxcdew=1 HTTP/1.1 "404 710 0.015"-""-"" mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0) Opera 7.11 [ZH-CN] "
