tomcat的日志分类
tomcat产生的访问日志数据
【localhost_access_log.Y-M-D.txt】
它记录的访问的时间,IP,访问的资料等相关信息
参数说明:
className
官方文档上说了:This MUST be set to
org.apache.catalina.valves.AccessLogValve to use the default access
log valve。
directory
日志文件存放的目录。通常设置为tomcat下已有的那个logs文件。
prefix
日志文件的名称前缀。
suffix
日志文件的名称后缀。
pattern
最主要的参数。
pattern。它的参数比较多。可以设置成common,combined两种格式。
common的值:%h %l %u %t %r %s %b
combined的值:%h %l %u %t %r %s %b %{Referer}i %{User-Agent}i
resolveHosts
如果是true,tomcat会将这个服务器IP地址通过DNS转换为主机名;如果是false,就直接写服务器IP地址。默认false。
rotatable
默认为true,tomcat生成的文件名为prefix(前缀)+.+时间(一般是按天算)+.+suffix(后缀),如:localhost_access_log.2007-09-22.txt。设置为false的话,tomcat会忽略时间,不会生成新文件,文件名就是:localhost_access_log.txt。长此以往,这个日志文件会超级大
condition
这个参数不太实用,可设置任何值,比如设置成condition="tkq",那么只有当ServletRequest.getAttribute("tkq")为空的时候,该条日志才会被记录下来。
fileDateFormat
顾名思义,就是时间格式嘛。但这个时间格式是针对日志文件名起作用的。咱们生成的日志文件全名:localhost_access_log.2016-09-22.txt,这里面的2016-09-22就是这么来的。如果想让tomcat每小时生成一个日志文件,也很简单,将这个值设置为:fileDateFormat="yyyy-MM-dd.HH",当然也可以按分钟生成什么的,自己改改吧^_^
* %a - Remote IP address // 这是记录访问者的IP,在日志里是127.0.0.1 * %A -
Local IP address //
这是记录本地服务器的IP,在日志里是192.168.254.108 * %b - Bytes
sent, excluding HTTP headers, or '-' if zero //
发送信息的字节数,不包括http头,如果字节数为0的话,显示为- * %B - Bytes
sent, excluding HTTP headers // 发送信息的字节数,不包括http头。 * %h - Remote
host name (or IP address if resolveHosts is false)
//服务器的名称。如果resolveHosts为false的话,这里就是IP地址了,例如我的日志里是10.217.14.16
* %H - Request protocol //访问者的协议,这里是HTTP/1.0
* %l - Remote logical username from identd
(always returns '-') // 官方解释:Remote logical username from identd
(可能这样翻译:记录浏览者进行身份验证时提供的名字)(always returns '-') *
%m - Request method (GET, POST, etc.) // 访问的方式,是GET还是POST
* %p - Local port on which this request was
received // 本地接收访问的端口 * %q - Query string
(prepended with a '?' if it exists) //
比如你访问的是aaa.jsp?bbb=ccc,那么这里就显示?bbb=ccc,就是querystring的意思
* %r - First line of the request (method and
request URI) // First line of the request (method and request URI)
请求的方法和URL * %s - HTTP status code of the response // http的响应状态码
* %S - User session ID // 用户的session
ID,这个session ID大家可以另外查一下详细的解释,反正每次都会生成不同的session ID
* %t - Date and time, in Common Log Format //
请求时间 * %u - Remote user that was authenticated
(if any), else '-' // 得到了验证的访问者,否则就是"-" * %U - Requested URL path
// 访问的URL地址,我这里是/rightmainima/leftbott4.swf * %v - Local server
name // 服务器名称,可能就是你url里面写的那个吧,我这里是localhost* %D - Time taken to
process the request, in millis // 请求消耗的时间,以毫秒记 * %T - Time taken to
process the request, in seconds //请求消耗的时间,以秒记
There is also support to write information from
the cookie, incoming header, the Session or something else in the
ServletRequest. It is modeled after the apache syntax:* %{xxx}i for
incoming headers* %{xxx}c for a specific cookie* %{xxx}r xxx is an
attribute in the ServletRequest* %{xxx}s xxx is an attribute in the
HttpSession

另外%r参数能打印出请求的url和get参数。如果url指定访问方式是post,post的参数是打印不出来的。当需要打印post参数,该怎么办?
server.xml配置
tomcat访问日志格式配置,在config/server.xml里Host标签下加上
-
<</span>Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
-
prefix="localhost_access_log." suffix=".txt"
-
pattern="%h %l %u %t "%r" [%{postdata}r] %s %{Referer}i %{User-Agent}i %T %b" />

在web.xml中添加配置该filter
