Logstash 를 통해 collectd 의 로그를 수신한다.



Logstash 설정

Logstash 를 설치후 다음과 같이 설정한다


config.reload.automatic: true
config.reload.interval: 3s

path.data: /var/lib/logstash
path.logs: /var/log/logstash


- pipeline.id: conf.collectd
  path.config: "/etc/logstash/conf.collectd/*.conf"


mkdir -p /etc/logstash/conf.collectd/


input {
  udp {
    source_ip_fieldname => "[ip]"
    port => 25826
    buffer_size => 1452
    type => 'collectd'
    codec => collectd {
      typesdb => ['/usr/share/collectd/types.db']
    }
  }
}

output {
  #file {
  #  path => "/var/log/logstash/collectd.log"
  #}

  elasticsearch {
    hosts => ["http://127.0.0.1:9200"]
    index => "collectd-%{+YYYY-MM-dd}"
    user => "logstash_writer"
    password => "PASSWORD"
    ecs_compatibility => disabled
  }
}


/usr/share/collectd/types.db 파일은 collectd 를 설치하면 생성된다. 혹은 collectd 가 설치된 서버로부터 types.db 파일을 복사하여 업로드 하여도 된다.


수집된 로그 확인

Logstash 를 재기동한 후 elastic 에서 수집된 로그를 확인한다.

혹은 ipmi-collectd.conf 파일의 output → file 부분의 주석을 제거하면, 수집된 로그를 확인할 수 있다.
