关键词：

利用 Filebeat去读取日志发送到 Logstash ,再由 Logstash 处理后发送给 Elasticsearch 。

一、Filebeat

项目日志文件：

利用 Filebeat 去读取文件，paths 下面配置路径地址，Filebeat 会自动去读取 /data/share/business_log/TA-*/debug.log 文件

#=========================== Filebeat prospectors =============================
 
filebeat.prospectors:
 
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.
 
- type: log
 
  # Change to true to enable this prospector configuration.
  enabled: true
 
  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    #- /usr/local/server/openresty/nginx/logs/*.log
    - /data/share/business_log/TA-*/debug.log
    #- c:programdataelasticsearchlogs*

filebeat 对于多行日志的处理

multiline:
    pattern: ‘^[0-2][0-9]:[0-5][0-9]:[0-5][0-9]‘
    negate: true
    match: after

上面配置的意思是：不以时间格式开头的行都合并到上一行的末尾（正则写的不好，忽略忽略）
pattern：正则表达式
negate：true 或 false；默认是false，匹配pattern的行合并到上一行；true，不匹配pattern的行合并到上一行
match：after 或 before，合并到上一行的末尾或开头
还有更多两个配置，默认也是注释的，没特殊要求可以不管它
max_lines: 500
timeout: 5s
max_lines：合并最大行，默认500
timeout：一次合并事件的超时时间，默认5s，防止合并消耗太多时间甚至卡死

nginx日志文件

#=========================== Filebeat prospectors =============================
 
filebeat.prospectors:
 
# Each - is a prospector. Most options can be set at the prospector level, so
# you can use different prospectors for various configurations.
# Below are the prospector specific configurations.
 
- type: log
 
  # Change to true to enable this prospector configuration.
  enabled: true
 
  # Paths that should be crawled and fetched. Glob based paths.
  paths:
    - /usr/local/server/openresty/nginx/logs/access.log
    - /usr/local/server/openresty/nginx/logs/error.log
    #- /data/share/business_log/TA-*/debug.log
    #- c:programdataelasticsearchlogs*

输出配置
注释掉 Elasticsearch 下面的配置项，并配置 Logstash 下面的配置，会将 Filebeat 读取到的日志文件发送到 hosts 里面配置的 Logstash 服务器上面去

#----------------------------- Logstash output --------------------------------
output.logstash:
  # The Logstash hosts
  hosts: ["172.18.1.152:5044","172.18.1.153:5044","172.18.1.154:5044"]
  index: "logstash-%+yyyy.MM.dd"
 
  # Optional SSL. By default is off.
  # List of root certificates for HTTPS server verifications
  #ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]
 
  # Certificate for SSL client authentication
  #ssl.certificate: "/etc/pki/client/cert.pem"
 
  # Client Certificate Key
  #ssl.key: "/etc/pki/client/cert.key"

Filebeat 启动命令：nohup ./filebeat -e -c filebeat-TA.yml >/dev/null 2>&1 &

二、Logstash

基本配置

Logstash 本身不能建立集群，Filebeat 连接 Logstash 后会自动轮询 Logstash 服务器是否可用，把数据发送到可用的 Logstash 服务器上面去

Logstash 配置，监听5044端口，接收 Filebeat 发送过来的日志，然后利用 grok 对日志过滤，根据不同的日志设置不同的 type，并将日志存储到 Elasticsearch 集群上面

项目日志跟nginx日志配置在一起，elasticsearch 配置的索引 index 里面不能大写，不然会出现奇怪的bug

input 
  beats 
    port => "5044"
  

 
filter 
 
  date 
      match => ["@timestamp", "yyyy-MM-dd HH:mm:ss"]
  
  grok 
    match => 
      "source" => "(?<type>([A-Za-z]*-[A-Za-z]*-[A-Za-z]*)|([A-Za-z]*-[A-Za-z]*)|access|error)"
    
  
 

 
output 
  # 针对不同的项目日志需要写不同的判断项
  if [type] == "MS-System-OTA"
    elasticsearch 
      hosts => ["172.18.1.152:9200","172.18.1.153:9200","172.18.1.154:9200"]
      index => "logstash-ms-system-ota-%+YYYY.MM.dd"
    
  else if [type] == "access" or [type] == "error"
    elasticsearch 
      hosts => ["172.18.1.152:9200","172.18.1.153:9200","172.18.1.154:9200"]
      index => "logstash-nginx-%+YYYY.MM.dd"
    
  else
    elasticsearch 
      hosts => ["172.18.1.152:9200","172.18.1.153:9200","172.18.1.154:9200"]
    
  
  stdout 
    codec => rubydebug
