Filebeat定义index

一、Filebeat自定义index

默认情况下filebeat写入elasticsearch中的数据，将会自动生成一个flibe-version-date的索引，采集的数据都在这个索引下面。根据要求希望将不同服务的日志输出到各自对应的索引。

如下：

配置文件

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /data/logs/pb-dubbo-user/err_*.log
  fields:
    source: dubbo-user
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: true
  multiline.match: after 

- type: log
  enabled: true
  paths:
    - /data/logs/pb-server-admin/err_*.log
  fields:
    source: server-admin
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: true
  multiline.match: after

- type: log
  enabled: true
  paths:
    - /data/logs/pb-dubbo-product/err_*.log
  fields:
    source: dubbo-product
  multiline.pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
  multiline.negate: false
  multiline.match: after

- type: log
  enabled: true
  paths:
    - /data/logs/pb-server-api/err_*.log
  fields:
    source: server-api
  multiline.pattern: '^[[:space:]]+(at|\.{3})\b|^Caused by|^java\.net|^org\.spring|^org\.apache:'
  multiline.negate: true
  multiline.match: after

filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false


setup.template.settings:
  index.number_of_shards: 1

# 定义模板的相关信息
setup.template.name: "pb_log"
setup.template.pattern: "pb-*"
setup.template.overwrite: true
setup.template.enabled: true

#7版本自定义ES的索引需要把ilm设置为false
setup.ilm.enabled: false


setup.kibana:
 hosts: "192.168.100.163:5601"

output.elasticsearch:
  hosts: ["192.168.100.163:9200"]
  index: "pb-%{[fields.source]}-*"
  indices:
    - index: "pb-dubbo-user-%{+yyyy.MM.dd}"
      when.equals:
        fields.source: "dubbo-user"
    - index: "pb-server-admin-%{+yyyy.MM.dd}"
      when.equals:
        fields.source: "server-admin"
    - index: "pb-server-api-%{+yyyy.MM.dd}"
      when.equals:
        fields.source: "server-api"
    - index: "pb-dubbo-product-%{+yyyy.MM.dd}"
      when.equals:
        fields.source: "dubbo-product"

processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~

　　如果不想以日期来划分，可以将{+yyyy.MM.dd}日期格式去掉

二、Filebeat合并多行日志

将JAVA堆栈跟踪日志组合成一个message

示例：

Exception in thread "main" java.lang.IllegalStateException: A book has a null property
       at com.example.myproject.Author.getBookIds(Author.java:38)
       at com.example.myproject.Bootstrap.main(Bootstrap.java:14)
Caused by: java.lang.NullPointerException
       at com.example.myproject.Book.getId(Book.java:22)
       at com.example.myproject.Author.getBookIds(Author.java:35)
       ... 1 more

要将这些行整合到Filebeat中的单个事件中，请使用以下多行配置：

multiline.pattern: '^[[:space:]]+(at|\.{3})\b|^Caused by:'
multiline.negate: false
multiline.match: after

C风格的日志

一些编程语言在一行末尾使用反斜杠()字符，表示该行仍在继续，如本例中所示:

printf ("%10.10ld  \t %10.10ld \t %s\
  %f", w, x, y, z );

要将这些行整合到Filebeat中的单个事件中，请使用以下多行配置

multiline.pattern: '\\$'
multiline.negate: false
multiline.match: before

此配置将以"\"字符结尾的任何行与后面的行合并。

时间戳

来自Elasticsearch等服务的活动日志通常以时间戳开始，然后是关于特定活动的信息，如下例所示：

[2015-08-24 11:49:14,389][INFO ][env                      ] [Letha] using [1] data paths, mounts [[/
(/dev/disk1)]], net usable_space [34.5gb], net total_space [118.9gb], types [hfs]
