日志分析 logstash elashsearch kibana
日志分析界面:
logstash(分析端) + elashsearch(存储端) + kibana(展示端)
工具:
进行数据整理
statsd
1、diamond --> statsd --> graphite
2、实时收集数据的做法:
logstash --> statsd --> graphite
日志收集可视化(LEK):
logstash + elasticsearch + kibana
legend: logstash --》 redis --》 ElasticSearch
logstash包括两种工作方式:
standalone : logstash on a single
logstash ---> elasticsearch ---> kibana
centralized: logstash with multiple servers

LEK安装:
测试机:X.X.X.X
需要java环境(java -version)
install JDK:
wget http://down1.chinaunix.net/distfiles/jdk-6u13-dlj-linux-i586.bin
sh jdk-6u13-dlj-linux-i586.bin
配置环境变量:
vim /etc/profile
export JAVA_HOME=/usr/java
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH
安装路径定义:
DIR = /root/lek/
1、安装elasticsearch
mkdir $DIR/elasticsearch
方式1:
cd elasticsearch
wget http://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.90.5.zip
unzip elasticsearch-0.90.5.zip
elasticsearch解压即可使用,启动方式:
cd elasticsearch-0.90.5
bin/elasticsearch -f
访问测试:
curl -X GET http://192.168.70.31:9200
方式2:(个人感觉这种方式方便一些)
rpm包的方式,rpm -ivh elasticsearch-0.90.9.noarch.rpm
/etc/init.d/elasticsearch start
elasticsearch head -->分布式搜索elasticsearch集群管理工具head
/usr/share/elasticsearch/bin/plugin -install mobz/elasticsearch-head
http://192.168.70.31/_plugin/head/
3、安装logstash
mkdir $DIR/logstash
cd logstash
wget http://download.elasticsearch.org/logstash/logstash/logstash-1.2.1-flatjar.jar
logstash 下载即可使用,命令行参数可参考http://logstash.net/docs/1.2.1/flags
4、安装kibana
mkdir $DIR/kibana
cd kibana
wget http://download.elasticsearch.org/kibana/kibana/kibana-latest.zip
unzip kibana-latest.zip
cp -r kibana-latest /var/www/html
访问地址:
http://X.X.X.X/kibana-latest/index.html
修改配置文件:
vim /var/www/html/kibana-latest/config.js
elasticsearch: "http://X.X.X.X:9200"
增加中国地图:
将map.cn.js文件放在/var/www/html/kibana-latest/app/panels/map/lib/下
修改/var/www/html/kibana-latest/app/panels/map/editor.html
将[‘world‘,‘europe‘,‘usa‘]修改成[‘world‘,‘europe‘,‘usa‘,‘cn‘]即可
5、lek启动程序
创建logstash配置文件
cd logstash
vim simple.conf
input {
file {
type => "syslog"
path => "/var/log/httpd/access_log"
}
}
output {
elasticsearch {
#embedded => true
host => "elasticsearch ip"
}
}
用这个配置文件启动logstash agent
使用logstash 自带的elasticsearch:
java -jar logstash-1.2.2-flatjar.jar agent -f simple.conf -- web &
使用单独elasticsearch:
java -jar logstash-1.2.2-flatjar.jar agent -f simple.conf &
修改完kibana后重启httpd,然后就可以通过kibana的界面看到日志情况
6、logstash高级应用
splunk日志处理和分析最好的产品,但是是付费的。免费的只支持500M日志
在logstash里边去过滤php日志
input {
file {
path => "/var/log/php_erross.log"
type => "phperror"
}
}
filter {
if [type] == "phperror" {
grok {
patterns_dir => "./p" #p里边存放的为匹配模式
match => ["message","%{PHP_LOG}"]
}
date {
match => [ "timestamp","","dd-MMM-yyyy HH:mm:ss" ]
}
punct {}
}
}
output {
elasticsearch { embedded => true }
}
文件夹p下面的内容:p/phperror
内容来自于github
PHP_TS ...
PHP_LOG ...
