Logstash事件处理有三个阶段:inputs → filters → outputs。是一个接收,处理,转发日志的工具。支持系统日志,webserver日志,错误日志,应用日志,总之包括所有可以抛出来的日志类型。
如上图,Logstash的数据处理过程主要包括:Inputs,Filters,Outputs 三部分,另外在Inputs和Outputs中可以使用Codecs对数据格式进行处理。这四个部分均以插件形式存在,用户通过定义pipeline配置文件,设置需要使用的input,filter,output,codec插件,以实现特定的数据采集,数据处理,数据输出等功能 。
Inputs:用于从数据源获取数据,常见的插件如file, syslog, redis, beats 等
Filters:用于处理数据如格式转换,数据派生等,常见的插件如grok, mutate, drop, clone, geoip等
Outputs:用于数据输出,常见的插件如elastcisearch,file, graphite, statsd等
Codecs:Codecs(编码插件)不是一个单独的流程,而是在输入和输出等插件中用于数据转换的模块,用于对数据进行编码处理,常见的插件如json,multiline。Logstash不只是一个input | filter | output 的数据流,而是一个 input | decode | filter | encode | output 的数据流!codec 就是用来 decode、encode 事件的。
Input:输入数据到logstash。
一些常用的输入为:
file:从文件系统的文件中读取,类似于tial -f命令
syslog:在514端口上监听系统日志消息,并根据RFC3164标准进行解析
redis:从redis service中读取
beats:从filebeat中读取
Filters:数据中间处理,对数据进行操作。
一些常用的过滤器为:
grok:解析任意文本数据,Grok 是 Logstash 最重要的插件。它的主要作用就是将文本格式的字符串,转换成为具体的结构化的数据,配合正则表达式使用。内置120多个解析语法。
官方提供的grok表达式:https://github.com/logstash-plugins/logstash-patterns-core/tree/master/patterns
grok在线调试:https://grokdebug.herokuapp.com/
mutate:对字段进行转换。例如对字段进行删除、替换、修改、重命名等。
drop:丢弃一部分events不进行处理。
clone:拷贝 event,这个过程中也可以添加或移除字段。
geoip:添加地理信息(为前台kibana图形化展示使用)
Outputs:outputs是logstash处理管道的最末端组件。一个event可以在处理过程中经过多重输出,但是一旦所有的outputs都执行结束,这个event也就完成生命周期。
一些常见的outputs为:
elasticsearch:可以高效的保存数据,并且能够方便和简单的进行查询。
file:将event数据保存到文件中。
graphite:将event数据发送到图形化组件中,一个很流行的开源存储图形化展示的组件。
Codecs:codecs 是基于数据流的过滤器,它可以作为input,output的一部分配置。Codecs可以帮助你轻松的分割发送过来已经被序列化的数据。
一些常见的codecs:
json:使用json格式对数据进行编码/解码。
multiline:将汇多个事件中数据汇总为一个单一的行。比如:java异常信息和堆栈信息。
Logstash功能
Logstash主要对日志进行过滤处理,也能用来做日志收集。但日志采集一般不用logstash
输入支持: 标准输入、文本日志输入等
输出支持: 标准输出、输出到es等
Logstash的安装
yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
yum localinstall logstash-7.6.2.rpm
Logstash的JVM配置文件更新jvm.options
-Xms200M
-Xmx200M
Logstash最简单配置/etc/logstash/conf.d/logstash.conf
input{
stdin{}
}
output{
stdout{
codec=>rubydebug
}
}
Logstash的启动和测试
/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/logstash.conf
输入字符,查看输出
安装
Logstash读日志文件实战
安装nginx来提供日志输入
yum install nginx -y
编辑nginx的systemctl配置文件/usr/lib/systemd/system/nginx.service,删除底下
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=process
PrivateTmp=true
Logstash收集日志注意点
默认logstash用logstash用户启动,日志需要给logstash用户读权限
需要有新日志产生,刚启动老的日志默认不读取
输入读取nginx日志
input {
file {
path => "/var/log/nginx/access.log"
}
}
output{
stdout{
codec=>rubydebug
}
}
Logstash的启动
systemctl enable logstash
systemctl restart logstash
观察日志:/var/log/messages
logstash读取nginx日志
input {
file {
path => "/var/log/nginx/access.log"
}
}
output {
elasticsearch {
hosts => ["http://xxx:9200", "http://xxx:9200"]
user => "elastic"
password => "sjgpwd"
index => "sjgnginx-%{+YYYY.MM.dd}"
}
}
Logstash配置重载,重启Logstash慢
kill -1 pid
logstash将日志输出到es
模拟Nginx日志产生
while true;do
curl 127.0.0.1/sjgsjg
curl 192.168.238.90/sjg666
sleep 5
done
Logstash正则提取Nginx日志
为什么需要提取?使用一整行日志无法分析,需要提取单独的字段
分析哪个IP访问量大
分析Nginx的响应状态码
Nginx日志格式
192.168.238.90 - - [01/Aug/2020:14:53:35 +0800] "GET /sjg666 HTTP/1.1" 404 3650 "-" "Chrome xxx" "-"
Nginx日志格式配置
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
$remote_addr 访问请求地址
$remote_user nginx登录的用户
$time_local 访问时间
$request 请求的动作 目录 协议
$status 返回状态
$body_bytes_sent 当前请求的字节数
$http_referer 页面的head信息从哪个页面发送的请求
$http_user_agent 使用的代理软件
$http_x_forwarded_for http真实请求头

Grok提取利器,需要掌握正则表达式。借助Kibana的Grok工具验证提取
自写正则提取(建议)
内置规则提取(简化):/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-patterns-core-4.1.2/patterns/grok-patterns
Grok自写正则提取语法:(?<字段名>自写正则表达式)
(?
内置正则提取语法:%{内置正则表达式:字段名}
%{IP:remote_addr} - (%{WORD:remote_user}|-) \[%{HTTPDATE:time_local}\] "%{WORD:method} %{NOTSPACE:request} HTTP/%{NUMBER}" %{NUMBER:status} %{NUMBER:body_bytes_sent} %{QS} %{QS:http_user_agent}
混合语法提取
(?
普通正则表达式符号
. 表示任意一个字符,* 表示前面一个字符出现0次或者多次
[abc]表示中括号内任意一个字符,[^abc]表示非中括号内的字符
[0-9]表示数字,[a-z]表示小写字母,[A-Z]表示大写字母,[a-zA-Z]表示所有字母,[a-zA-Z0-9]表示所有字母+数字
[^0-9]表示非数字
^xx表示以xx开头,xx$表示以xx结尾
\s表示空白字符,\S表示非空白字符,\d表示数字
扩展正则表达式,在普通正则基础上再进行扩展
?表示前面字符出现0或者1次,+前面字符出现1或者多次
{a}表示前面字符匹配a次,{a,b}表示前面字符匹配a到b次
{,b}表示前面字符匹配0次到b次,{a,}前面字符匹配a或a+次
string1|string2表示匹配string1或者string2

}
}
正则提取nginx日志
Kibana显示感叹号问题处理
Kibana索引刷新
Kibana索引的操作并不会影响到数据,删除重建也没问题
Logstash字段特殊处理-替换或转类型
http_user_agent包含双引号,需要去除
filter {
grok {
match => {
"message" => '%{IP:remote_addr} - (%{WORD:remote_user}|-) \[%{HTTPDATE:time_local}\] "%{WORD:method} %{NOTSPACE:request} HTTP/%{NUMBER}" %{NUMBER:status} %{NUMBER:body_bytes_sent} %{QS} %{QS:http_user_agent}'
}
remove_field => ["message"]
}
mutate {
gsub => [ "http_user_agent",'"',"" ]
}
}
Logstash字符串转整形
mutate{
gsub => [ "http_user_agent",'"',"" ]
convert => { "status" => "integer" }
convert => { "body_bytes_sent" => "integer" }
}
字段替换或转类型处理
Logstash替换时间戳@timestamp
Nginx模拟用户访问
while true;do
curl 192.168.238.90/sjg666
curl 127.0.0.1
sleep 2
done
场景假设
假设我们要分析用户昨天的访问日志
Logstash分析所有Nginx日志,发现问题
input {
file {
path => "/var/log/nginx/access.log"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
两种时间
发送日志时间,无法分析日志
用户的访问时间在日志里,需要以日志里的为准,分析的结果才准确
以用户访问时间为准,格式为01/Aug/2020:10:34:20 +0800
filter {
grok {
match => {
"message" => '%{IP:remote_addr} - (%{WORD:remote_user}|-) \[%{HTTPDATE:time_local}\] "%{WORD:method} %{NOTSPACE:request} HTTP/%{NUMBER}" %{NUMBER:status} %{NUMBER:body_bytes_sent} %{QS} %{QS:http_user_agent}'
}
remove_field => ["message"]
}
date {
match => ["time_local", "dd/MMM/yyyy:HH:mm:ss Z"]
target => "@timestamp"
}
}
日志里如果有不同的时间格式,覆盖的时候格式要对应
20/Feb/2019:14:50:06 -> dd/MMM/yyyy:HH:mm:ss
2016-08-24 18:05:39,830 -> yyyy-MM-dd HH:mm:ss,SSS
手动统计Nginx的请求和网页显示进行对比
cat /var/log/nginx/access.log |awk '{print $4}'|sed 's/:[0-9][0-9]$//g'|sort |uniq -c
时间戳覆盖后删除
mutate {
gsub => [ "http_user_agent",'"',"" ]
convert => { "status" => "integer" }
convert => { "body_bytes_sent" => "integer" }
remove_field => ["time_local"]
}
替换时间戳
Logstash正则提取异常处理
Logstash改成分析最新日志
input {
file {
path => "/var/log/nginx/access.log"
}
}
正则提取有异常的情况
echo "sjgmethods xxx xxx" >> /var/log/nginx/access.log
tags: _grokparsefailure
设置正则出错提取到另外的索引里
output {
if "_grokparsefailure" not in [tags] and "_dateparsefailure" not in [tags] {
elasticsearch {
hosts => ["http://192.168.238.90:9200", "http://192.168.238.92:9200"]
user => "elastic"
password => "sjgpwd"
index => "sjgnginx-%{+YYYY.MM.dd}"
}
}
else{
elasticsearch {
hosts => ["http://192.168.238.90:9200", "http://192.168.238.92:9200"]
user => "elastic"
password => "sjgpwd"
index => "sjgfail-%{+YYYY.MM.dd}"
}
}
}
Kibana图形简单使用
模拟数据
while true;do
curl 192.168.238.90/sjg666;
curl 127.0.0.1;
sleep 2;
done
首页区域
可以根据时间查看访问量:每分钟访问量
可以根据某个字段查询
可以单独看某个字段的统计
Kibana图形有建立,选择terms去查看对应的数据
饼图的创建 pie_remote_addr
表的创建 table_remote_addr
Kibana面板的创建sjg_dash
创建面板
在面板上添加图形
建议采用Grafana展示
正则替换异常处理
