filebeat.prospectors #用于定义数据原型，检测日志或是发现日志- input_type: log #指定数据的输入类型，默认为log，另外还可以指定stdin paths: #自定需要监控的日志文件路径；可以是完整的日志路径也可以是模糊的匹配格式 - /var/log/messages #指定系统日志位置 fields: #定义日志来源，可以添加自定义字段，其实就是定义Kafka消息队列的topic主题名称，如果kafka消息队列中没有该名称，会自动生成 log_topic: test paths: #与上述一样定义需要监控的日志文件路径，不够这次是定义apache-web服务的日志 - /etc/httpd/logs/* fields: #定义日志来源，生成kafka消息队列topic主题 log_topic: webapacheprocessors: #这个地方需要注意，此配置是将日志输出格式过滤掉，一般情况下，一些无用的日志字段我们可以删除，只看关键性的信息- drop_fields: fields: ["beat", "input_type", "source", "offset",]name: "192.168.37.134" #设置filebeat收集日志中对应的主机名称，，如果设置为空，这使用该机器的主机名称，这里这是本地IP，便于区分多台主机的日志信息output.kafka: #多种输出类型，可支持想kafka，logstash，elasticsearch输出日志信，在这里是将日志信息输出到Kafka中， enabled: true 启动该模块 hosts: ["192.168.37.134:9092", "192.168.37.135:9092", "192.168.37.136:9092"] #指定输出数据到kafka集群上，地址与端口号想对应 version: "0.10" topic: '%{[fields][log_topic]}' #指定要发送数据到kafka集群的哪个topic，与上述的"fields: log_topic："相对应，这是6.x的配置 partition.round_robin: #开启kafka的partition分区 reachable_only: true worker: 2 required_acks: 1 compression: gzip #压缩格式 max_message_bytes: 10000000 #压缩格式字节大小logging.level: debug #日志类型为debug root@es-node1 bin]#nohup ./filebeat -e -c filebeat.yml &

以下是apache是通过json校验的日志输出信息

上述Filebeat收集到的日志格式信息量过大，我们只需要收集关键性的日志信息即可，无用的可以过滤掉，配置如下
processors:- drop_fields: fields: ["beat", "input_type", "source", "offset",]
过滤到之后 的apache日志输出如下所示
1 { 2 "@timestamp": "2018-08-16T05:10:02.261Z", 3 "@metadata": { 4 "beat": "filebeat", 5 "type": "doc", 6 "version": "6.3.2", 7 "topic": "webapache" 8 }, 9 "message": "192.168.37.1 - - [16/Aug/2018:13:09:53 +0800] \"GET /noindex/css/fonts/Bold/OpenSans-Bold.ttf HTTP/1.1\" 404 238 \"http://192.168.37.129/noindex/css/open-sans.css\" \"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36\"",10 "fields": {11 "log_topic": "webapache"12 },13 "host": {14 "name": "192.168.37.129"15 }16 } 【filebeat.yml配置文件】
文章最后结尾是filebeat的过滤和未过滤的配置，方便直接复制粘贴；
为什么这我们再次将filebeat的配置文件粘贴出来呢？因为我被这个坑了整整一天的时间，启动fiebeat一直报错，网上关于6.x版本和kafka整合的博客和资料几乎没有，出现报错，也没有解决方案，当时直接气晕，对外寻求帮助，也没有解决方案，最后上层技术大佬，才得以解决，这个filebeat,yml实在是太多坑了，都是因为JSON格式，下面是我具体的报错信息
error initializing publisher: missing required field accessing 'output.kafka.hosts'
提示缺少访问“输出. Kafka . hosts”的必需字段，就这个，我纠结了一天，好在问题解决了，心累~
