logstash 收集tomcat异常信息

bco

我所期望达到的效果，就是每个日期一条，在kibana界面也是一条。多行异常的也是一条。

其实，很简单，就是加个反向判断。

logstash原理

一个客户端，一个服务器，就是这样的模式

没什么神奇的，最麻烦的正则匹配，不好弄。听说storm更好用。

1.client配置

cat /etc/logstash/conf.d/shipper.conf

input {
    file {
        path => ["/opt/src/logs/*/*/*/*"]
        type => "service"
        start_position => "beginning"
    }
}
filter {
  if [type] == "service" {
      multiline {
          patterns_dir => "/etc/logstash/conf.d"
          pattern => "(^%{MYTIMESTAMP})"
          negate => true
          what => "previous"
      }
      }
  grok {
        patterns_dir => "/etc/logstash/conf.d"
        match => [ "message", "%{MYLOG}" ]
        add_field => [ "log_ip", "随便写" ]
  }
}
output {
        stdout {}
        redis {
        host => "你的服务端ip"
        port => 6379
        password => "xx"
        data_type => "list"
        key => "key_count"
    }
}

patterns_dir => "/etc/logstash/conf.d" 这个东西就是正则表达式

新建一个文件 cat /etc/logstash/conf.d/j2ee

JAVACLASS (?:[a-zA-Z$_][a-zA-Z$_0-9]*\.)*[a-zA-Z$_][a-zA-Z$_0-9]*
HTTPPORT  ([a-zA-Z$_0-9]*\-)*([0-9])
JAVALOGMESSAGE (.*)
MYTIMESTAMP 20%{YEAR}-%{MONTHNUM}-%{MONTHDAY}%{HOUR}:%{MINUTE}:%{SECOND}
MYLOG %{MYTIMESTAMP:mytimestamp}\s\[%{HTTPPORT:port}\]\s%{LOGLEVEL:level}\s%{JAVACLASS:class}\s-%{JAVALOGMESSAGE:logmessage}

我的日志格式是这样的

2016-10-2015:52:01.174 [http-apr-8282-exec-4] INFO  c.e.w.c.... -resp:

如果你的日志不一样，那么j2ee文件要做相应的修改

http://grokdebug.herokuapp.com/ 这个网站可以测试

比如

启动脚本logstash.sh

#!/bin/bash
. /etc/init.d/functions
function start(){
cd /home/
/opt/logstash/bin/logstash -f /etc/logstash/conf.d/shipper.conf & >>/dev/null 2>&1
}
function stop(){
sudo kill -9 `ps -ef|grep logstash|grep -v grep|awk '{print $2}'`
#for i in `ps -ef|grep logstash|grep -v grep|awk '{print $2}'`
#do;sudo kill -9 $i;done
}
case $1 in
start)
start
;;
stop)
stop
;;
*)
printf "Usage sh *.sh start|stop"
;;
esac

sh logstash.sh stop/start

2.server配置

cat /etc/logstash/conf.d/indexer.conf

input {
    redis {
        host => "你的服务端ip"
        port => 6379
        password => "xx"
        type => "redis-input"
        data_type => "list"
        key => "key_count"
    }
}
output {
    stdout {}
    elasticsearch {
        cluster => "elasticsearch"
        codec => "json"
        protocol => "http"
        }
}

3.kibana效果

多行为一行就不截图了

注意有事启动了logstash，但是没有日志传送过来

• input file 匹配类型，正则有问题
  
  
• filter正则有问题
  
  

总而言之，就是配置有问题。

demo

client
cat demo.conf
input {
    file {
        path => ["/home/python/demo/*/*/*/*"]
        type => "demo"
        start_position => "beginning"
    }
}
filter {
  if [type] == "demo" {
      multiline {
          patterns_dir => "/etc/logstash/conf.d/patterns"
          pattern => "(^%{MYTIMESTAMP})"
          negate => true
          what => "previous"
      }
      }
  grok {
        patterns_dir => "/etc/logstash/conf.d/patterns"
        match => [ "message", "%{MYLOG}" ]
        add_field => [ "log_ip", "172.29.xx.xx" ]
  }
}
output {
        stdout {}
        redis {
        host => "172.29.xx.xx"
        port => 6379
        password => "xxxxxx"
        data_type => "list"
        key => "key_count"
    }
}

cd /etc/logstash/conf.d/patterns
cat j2ee
