ELK系列~Nxlog日志收集加转发(解决log4日志换行导致json转换失败问题)

本文章将会继承上一篇文章,主要讲通过工具来进行日志的收集与发送,《ELK系列~NLog.Targets.Fluentd到达如何通过tcp发到fluentd

Nxlog是一个日志收集工具,它将系统日志,或者指定的日志文件,统配符文件找到,然后加工,最后发送到目标位置。而目标位置有很多种,如文件系统,fluentd系统等,下面我们介绍一个使用场景,也是经常涉及到的场景。

  1. log4产生日期,日期文件名,统一后缀,按日志级别命名
  2. nxlog工具,配置,启动,发送数据
  3. fluentd配置,接受数据,打印数据

一 log4产生日期,日期文件名,统一后缀,按日志级别命名

<?xml version="1.0"?>
<configuration>
<configSections>
  <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web> <log4net>
<logger name="ErrorLog">
<level value="ERROR"></level>
<appender-ref ref="ErrorLog"></appender-ref>
</logger>
<appender name="ErrorLog" type="log4net.Appender.RollingFileAppender">
<param name="File" value="logs\\" />
<param name="AppendToFile" value="true" />
<param name="StaticLogFileName" value="false" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd&quot;Error.log&quot;" />
<layout type="log4net.Layout.PatternLayout">
</layout>
</appender> <logger name="InfoLog">
<level value="INFO"></level>
<appender-ref ref="InfoLog"></appender-ref>
</logger>
<appender name="InfoLog" type="log4net.Appender.RollingFileAppender">
<param name="File" value="logs\\" />
<param name="AppendToFile" value="true" />
<param name="StaticLogFileName" value="false" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd&quot;Info.log&quot;" />
<layout type="log4net.Layout.PatternLayout">
</layout>
</appender> <logger name="WarnLog">
<level value="Warn"></level>
<appender-ref ref="WarnLog"></appender-ref>
</logger>
<appender name="WarnLog" type="log4net.Appender.RollingFileAppender">
<param name="File" value="logs\\" />
<param name="AppendToFile" value="true" />
<param name="StaticLogFileName" value="false" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd&quot;Warn.log&quot;" />
<layout type="log4net.Layout.PatternLayout">
</layout>
</appender> <logger name="FatalLog">
<level value="Fatal"></level>
<appender-ref ref="FatalLog"></appender-ref>
</logger>
<appender name="FatalLog" type="log4net.Appender.RollingFileAppender">
<param name="File" value="logs\\" />
<param name="AppendToFile" value="true" />
<param name="StaticLogFileName" value="false" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd&quot;Fatal.log&quot;" />
<layout type="log4net.Layout.PatternLayout">
</layout>
</appender>
</log4net>
</configuration>

产生日志的方法如下

            log4net.Config.XmlConfigurator.Configure(new FileInfo("log4.config"));
for (int i = ; i < ; i++)
{
LogHelper.Info("test");
}
Console.WriteLine("end");

上面代码将会产生日志文件,命名比较固定,方法日志的收集工作。

二 nxlog工具,配置,启动,发送数据

安装:https://docs.fluentd.org/v0.12/articles/windows

配置:去掉了log4产生日志每行后面的\r标记,如果不进行处理,在json转换时会有问题

## This is a sample configuration file. See the nxlog reference manual about the
## configuration options. It should be installed locally and is also available
## online at http://nxlog.org/docs/ ## Please set the ROOT to the folder your nxlog was installed into,
## otherwise it will not start. #define ROOT C:\Program Files\nxlog
define ROOT C:\Program Files (x86)\nxlog Moduledir %ROOT%\modules
CacheDir %ROOT%\data
Pidfile %ROOT%\data\nxlog.pid
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log <Extension json>
Module xm_json
</Extension>
<Extension _syslog>
Module xm_syslog
</Extension> <Input in>
Module im_file
File "c:\dotnet\20*.log"
Exec $raw_event = replace($raw_event, "\r\n", " ");
Exec $raw_event = replace($raw_event, "\r", " ");
Exec $raw_event = replace($raw_event, "\n", " ");
Exec $raw_event = replace($raw_event, "0x0A", " ");
Exec $raw_event = replace($raw_event, "0x0DA", " ");
Exec $raw_event = replace($raw_event, "0x0D", " "); </Input>
<Output out>
Module om_tcp
Host 192.168.200.214
Port
Exec $raw_event =$raw_event + "\n";
</Output> <Route >
Path in => out
</Route>

启动:nxlog -f -c conf/nxlog.conf

查看:打开fluentd端,查看它的日志,发现我们的日志已经过来了

这个东西,我在google上找了好久,最后总算是功夫不负有心人,让我找对了!当然也证明了最初的猜想是正确的,即在output中对字符进行过滤!

三 fluentd配置,接受数据,打印数据

1 运行脚本,升级需要的文件夹和文件

mkdir /scripts/fluentd -p
cd /scripts/fluentd cat > Dockerfile << 'EOF'
FROM fluent/fluentd:v0.-onbuild ENV TZ=Asia/Shanghai
RUN echo "http://mirrors.aliyun.com/alpine/v3.5/main" >/etc/apk/repositories \
&& echo "http://mirrors.aliyun.com/alpine/v3.5/community" >>/etc/apk/repositories \
&& apk add --update tzdata \
&& apk add curl \
&& ln -snf /usr/share/zoneinfo/$TZ /etc/localtime \
&& echo $TZ > /etc/timezone RUN apk add --virtual .build-deps \
sudo build-base ruby-dev \
&& sudo gem sources --clear-all \
&& apk del .build-deps \
&& rm -rf /var/cache/apk/* \
/home/fluent/.gem/ruby/2.3.0/cache/*.gem
EOF mkdir plugins -p
mkdir -p /srv/volume/fluentd/ cat > /scripts/fluentd/fluent.conf << 'EOF'
<source>
@type forward
port 24224
bind 0.0.0.0
</source> <match **>
 @type stdout
</match>
EOF

2 生成镜像

docker build --no-cache --pull -t pilipa/tools/fluentd ./

2 docker上直接运行

docker run --privileged=true -v /scripts/fluentd/fluent.conf:/fluentd/etc/fluent.conf pilipa/tools/fluentd
启动后出现了配置和日志相关的输出信息

日志收集总算可以告一段落了!
