logstash簡介

logstash-2.2.2的配置：

從logstash-forward        到kafka的配置

[email protected]:~/logstashBeforeChangeConf$ cat /home/ubuntu/logstash-2.2.2/config/before-kafka-access.conf

input {

lumberjack {

port => "5044"

ssl_certificate => "/home/ubuntu/logstash-2.2.2/config/lumberjack.crt"

ssl_key =>"/home/ubuntu/logstash-2.2.2/config/lumberjack.key"

}

}

# stdout { codec => rubydebug }

bootstrap_servers => "sp1:9092,sp2:9092,sp3:9092,sp4:9092,sp5:9092,sp6:9092,sp7:9092"

compression_type => "snappy"

acks => ["1"]

value_serializer => "org.apache.kafka.common.serialization.StringSerializer"

timeout_ms => 10000

retries => 5

retry_backoff_ms => 100

send_buffer_bytes => 102400

workers => 2

}

}

}

從kafka到es配置

其中包括了對日誌各個欄位的解析,以及對異常日誌過濾（同時注意其中過濾了 不屬於當前時間前後5天的時間的日誌，為了防止異常日誌建立索引過多導致es報紅）
