ELK学习笔记之配置logstash消费kafka多个topic并分别生成索引

0x00 filebeat配置多个topic

filebeat.prospectors:
 
- input_type: log
  encoding: GB2312
#  fields_under_root: true
  fields:  ##添加字段
    serverip: 192.168.1.10
    logtopic: wap
  enabled: True
  paths:
        - /app/wap/logs/catalina.out
  multiline.pattern: '^\['  #java报错过滤
  multiline.negate:  true
  multiline.match: after
  tail_files: false
- input_type: log
  encoding: GB2312
 # fields_under_root: true
  fields:  ##添加字段
    serverip: 192.168.1.10
    logtopic: api
  enabled: True
  paths:
        - /app/api/logs/catalina.out
  multiline.pattern: '^\['  #java报错过滤
  multiline.negate:  true
  multiline.match: after
  tail_files: false
#----------------------------- Logstash output --------------------------------
output.kafka:
  enabled: true
  hosts: ["192.168.16.222:9092","192.168.16.237:9092","192.168.16.238:9092"]
  topic: 'elk-%{[fields.logtopic]}' ##匹配fileds字段下的logtopic
  partition.hash:
    reachable_only: true
  compression: gzip
  max_message_bytes: 1000000
  required_acks: 1
logging.to_files: true

0x01 查看是否输出到kafka

$  bin/kafka-topics.sh --list --zookeeper kafka-01:2181, kafka-02:2181,kafka-03:2181
elk-wap
elk-api

0x02 配置logstash集群

input{
  kafka{
    bootstrap_servers => "kafka-01:9092,kafka-02:9092,kafka-03:9092"
    topics_pattern  => "elk-.*"
    consumer_threads => 5
    decorate_events => true
    codec => "json"
    auto_offset_reset => "latest"
    group_id => "logstash1"##logstash 集群需相同
 
}
}
filter {
        ruby {
        code => "event.timestamp.time.localtime"
      }
 
        mutate {
        remove_field => ["beat"]
    }
        grok {
             match => {"message" => "\[(?<time>\d+-\d+-\d+\s\d+:\d+:\d+)\] \[(?<level>\w+)\] (?<thread>[\w|-]+) (?<class>[\w|\.]+) (?<lineNum>\d+):(?<msg>.+)"
 }
 
}
}
output {
   elasticsearch {
         hosts => ["192.168.16.221:9200","192.168.16.251:9200","192.168.16.252:9200"]
   #      index => "%{[fields][logtopic}" ##直接在日志中匹配，索引会去掉elk
         index =>  "%{[@metadata][topic]}-%{+YYYY-MM-dd}"
}
    stdout {
        codec => rubydebug
    }

0x03 Es查看是否创建索引

0x04 logstash集群配置

# 一机多实例，同一个配置文件，启动时只需更改数据路径
./bin/logstash -f test.conf --path.data=/usr/local/logdata/
# 多台机器 logstash配置文件group_id 相同即可
