日志写到redis中

redis安装配置略

input{

  path => "/var/log/access_log"
        type => "acccess_log"
        start_postition => "beginning"

}
output{
redis{
host => "ip"
port => 6379
db => "2"
data_type => "list"
key => "access_log"

            }

}

logstash从redis中读取日志

input{
     redis{
                   host => "ip"
                         port => 6379
                         db => "2"
                         data_type => "list"
                         key => "access_log"
                         type => "access_log"
            }
}
filter{
 grok{
     match => { "messages" => "%{COMBINEDAPACHELOG}"}  #logstash 默认组件
     }
}
output{
    elasticsearch {
                       hosts => ["ip:9200"]
                                 index => "access_log-%{+YYYY.MM.dd}"

            }

}
