从Tomcat的日志中排除某些请求

问题描述

我的Tomcat访问日志当前被来自负载均衡器的运行状况检查请求弄乱了，因此很难真正了解正在发生的事情.例如，使用GoAccess，我可以看到一些令人误解的统计信息:

My Tomcat access log is currently cluttered with health check requests from a load balancer, so it's rather hard to actually understand what's going on. For example, using GoAccess I can see some misleading statistics:

Hits      h% Vis.    v%   Bandwidth Mtd Proto    Data
 ----- ------ ---- ----- ----------- --- -------- ----
 46221 81.20%    2 0.02%   30.72 MiB GET HTTP/1.1 /geoserver/index.html
 16     0.03%    1 0.01%   50.23 KiB GET HTTP/1.1 /geoserver/wms?SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&FORMAT=image/jpeg.
 16     0.03%    1 0.01%  338.80 KiB GET HTTP/1.1 /geoserver/wms?SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&FORMAT=image/png.

该日志是使用Tomcat的标准访问日志阀.该阀门应该具有一个参数 conditionUnless ，我尝试使用该参数来消除对 index.html 发出的所有请求(在此处进行健康检查)，所以我可以安全地过滤掉所有这些).

The log is created using Tomcat's standard Access Log Valve. The valve is supposed to have a parameter, conditionUnless, which I try to use in order to get rid of all those requests being made to index.html (that's where health check goes, so I can safely filter out all of them).

根据文档，条件除非:

但是我不知道如何使用过滤器过滤出所有对 index.html 的请求，并在其中进行标记.显然， server.xml 中的以下内容是不够的:

But I can't figure out how to use Filters to filter out all requests to index.htmland flag them in some what. Obviously, the following in server.xml is not enough:

<Valve  className="org.apache.catalina.valves.AccessLogValve"
        directory="/var/log/tomcat8/accesslogs"
        prefix="node1" suffix=".log"
        pattern="combined"
        renameOnRotate="true"
        conditionUnless="index.html" />

如何排除对 index.html 的所有请求?

How can I exclude all requests to index.html?

推荐答案

您需要创建一个在Tomcat组中建议的过滤器，该过滤器将属性添加为 doLog

You need to create a filter as suggested in tomcat group that adds an attribute as doLog

public final class LoggingFilter implements Filter {

  private FilterConfig filterConfig = null;

  public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
    throws IOException, ServletException {

    request.setAttribute(filterConfig.getInitParameter("doLog"), "true");
    chain.doFilter(request, response);
  }
  public void destroy() {
    this.filterConfig = null;
  }
  public void init(FilterConfig filterConfig) {
    this.filterConfig = filterConfig;
  }
}

，然后使用 conditionIf

conditionIf="doLog"

并将过滤器添加到web.xml:

and add filter to web.xml:

<filter>
    <filter-name>LoggingFilter</filter-name>
    <filter-class>com.yourpackage.LoggingFilter</filter-class>
    <init-param>
        <param-name>logParam</param-name>
        <param-value>doLog</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>LoggingFilter</filter-name>
    <url-pattern>/geoserver/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>ERROR</dispatcher>
</filter-mapping>
<filter-mapping>
