7、將linux的系統日誌分爲auth和syslog

一、思路
對前面配置的優化。

分兩個topic，並在索引上體現分類

二、filebeat.yml

filebeat.inputs:
- type: log
  enabled: false
  paths:
    - /var/log/*.log

- type: filestream
  enabled: false
  paths:
    - /var/log/*.log

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

setup.template.settings:
  index.number_of_shards: 1

setup.kibana:
  host: "192.168.18.13:5601"
setup.template.overwrite: true
setup.template.enabled: true
setup.ilm.enabled: false

output.kafka:
  hosts: ["192.168.18.15:9092","192.168.18.16:9092"]
  topics:
    - topic: "linux_system_auth"
      when.equals:
        event:
          dataset: "system.auth"
    - topic: "linux_system_syslog"
      when.equals:
        event:
          dataset: "system.syslog"

processors:
  - add_host_metadata:
      when.not.contains.tags: forwarded

三、logstash
1、input.conf

input {
    kafka {
        bootstrap_servers => "192.168.18.15:9092,192.168.18.16:9092"
        topics => ["linux_system_auth"]
        add_field => { type_name => "linux_system_auth" }
        consumer_threads => 5
        codec => json
    }
    kafka {
                bootstrap_servers => "192.168.18.15:9092,192.168.18.16:9092"
                topics => ["linux_system_syslog"]
                add_field => { type_name => "linux_system_syslog" }
                consumer_threads => 5
                codec => json
        }
}

2、linux_system_out.conf

output {
    if  "linux_system_auth" in [type_name] {
        elasticsearch {
            hosts => ["192.168.18.13:9200"]
            index => "os-linux-auth-%{+YYYY.MM.dd}"
        }
    }
    if  "linux_system_syslog" in [type_name] {
                elasticsearch {
                        hosts => ["192.168.18.13:9200"]
                        index => "os-linux-syslog-%{+YYYY.MM.dd}"
                }
        }
}
