[2017-07-18]logstash配置示例

---

提醒

/etc/logstash/conf.d/下虽然可以有多个conf文件，但是Logstash执行时，实际上只有一个pipeline，它会将/etc/logstash/conf.d/下的所有conf文件合并成一个执行。如果希望每个input-filter-output都互相独立，那么就需要在input中加自定义field，后面所有的filter和output必须加if条件语句，如

input{
    rabbitmq{
        ...//略
        add_field=>{"custom_t"=>"auditing"}
    }
}
filter{
    if [custom_t]=="auditing"{
        date{
            ...//略
        }
    }
}
output{
    if [custom_t]=="auditing"{
        elasticsearch{
            ...//略
            index=>"auditing-%{+YYYY.MM.dd}"
        }
    }
}

1. Rabbitmq Input 解析审计日志

在/etc/logstash/conf.d目录新建logstash-rabbitmq-input.conf内容如下

input {
    rabbitmq {
        exchange => "RebusTopics"
        exchange_type => "topic"
        key => "Abp.Auditing.AuditingStores.AuditInfoMqMessage, Abplus.MqMessages.AuditingStore"
        durable => "true"
        queue => "logstash-input-rabbitmq"
        user => "user"
        password => "password"
        vhost => "dev_host"
        host => "127.0.0.1"
        add_field => {"env"=>"DEV"}
        add_field => {"test"=>"test"}
    }
}
filter{
    date{
        match => ["ExecutionTime","ISO8601"]
    }
}
output {
    elasticsearch { hosts => ["localhost:9200"] }
}

/usr/share/logstash/bin/logstash -f logstash-rabbitmq-input.conf --config.test_and_exit 检测配置是否正确

2. Filebeat Input 解析nginx日志（非默认格式）

nginx日志示例（非默认）

112.247.107.98 - - [27/Jul/2017:18:09:20 +0800] "POST /elasticsearch/_msearch HTTP/1.1" 200 0.830 0.830  21599 "http://abc.yourdomain.com/app/kibana" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/603.2.4 (KHTML, like Gecko) Version/10.1.1 Safari/603.2.4" "-" "10.173.163.214:5601" "abc.yourdomain.com:80"

在/etc/logstash/conf.d目录新增dev-nginx-filebeat.conf内容如下

input {
    beats {
        # The port to listen on for filebeat connections.
        port => 5044
        # The IP address to listen for filebeat connections.
        host => "127.0.0.1"
    }
}
filter {
    grok {
        keep_empty_captures => "true"
        match => { "message" => ["%{IPORHOST:nginx_access_remote_ip} - %{DATA:nginx_access_user_name} [%{HTTPDATE:nginx_access_time}] "%{WORD:nginx_access_method} %{DATA:nginx_access_url} HTTP/%{NUMBER:nginx_access_http_version}" %{NUMBER:nginx_access_response_code} %{NUMBER:nginx_time1} %{DATA:nginx_time2} %{NUMBER:nginx_access_body_sent_bytes} "%{DATA:nginx_access_referrer}" "%{DATA:nginx_access_agent}" "%{DATA:client_proxy_ip}" "%{IPORHOST:backend_server}:%{NUMBER:backend_server_port}" "%{IPORHOST:request_host}:%{NUMBER:request_host_port}""] }
        remove_field => "message"
    }
    date {
        match => [ "nginx_access_time", "dd/MMM/YYYY:H:m:s Z" ]
        remove_field => "nginx_access_time"
    }
    useragent {
        source => "nginx_access_agent"
        target => "nginx_access_user_agent"
        remove_field => "nginx_access_agent"
    }
}
output {
    elasticsearch {
        hosts => localhost
        manage_template => false
        index => "%{[@metadata][beat]}-%{+YYYY.MM.dd}"
        document_type => "%{[@metadata][type]}"
    }
}

/etc/filebeat/filebeat.yml 配置

filebeat.prospectors:
- input_type: log
paths:
    - /usr/local/nginx/logs/*.log
output.logstash:
hosts: ["localhost:5044"]

3. Filebeat Input 对接应用程序日志(Nlog)

首先固定日志格式，特别注意时间戳，示例Nlog target

...
<wrapper-target name="f2elk" xsi:type="AsyncWrapper" overflowAction="Grow" timeToSleepBetweenBatches="100" batchSize="100" queueLimit="10000">
  <target name="file2elk"
          xsi:type="File"
          layout="[${date:format=dd/MMM/yyyy:HH:mm:ss zz00:culture=en}] [${Env}] [${Proj}] [${level}] [${logger}] MSG[${message}]MSG EX[${exception:format=toString}]EX"
          fileName="d://logs/elk/${Env}.${Proj}.${date:format=yyyyMMdd}.log"
          keepFileOpen="false"
          encoding="utf-8" />
</wrapper-target>
...
<logger name="*" minlevel="Debug" writeTo="f2elk" />

filebeat.yml 示例

filebeat.prospectors:
- input_type: log
paths:
    - d:logselk*

multiline.pattern: ^[[0-9]{2}/[A-Za-z]{3}/[0-9]{4} #一定要注意时间戳格式和日志的输出匹配
multiline.negate: true
multiline.match: after

output.logstash:
hosts: ["localhost:5044"]

/etc/logstash/conf.d/nlog-input.conf 示例

input {
    beats {
        # The port to listen on for filebeat connections.
        port => 5046
        # The IP address to listen for filebeat connections.
        host => "10.173.163.214"
        add_field =>{"custom_t"=>"nlog"}
    }
}
filter {
    if [custom_t]=="nlog"{
    grok {
        keep_empty_captures => "true"
        match => { "message" => ["[%{HTTPDATE:LogTime}] [%{DATA:env}] [%{DATA:ProjectName}] [%{LOGLEVEL:Level}] [%{DATA:Logger}] MSG[%{DATA:LogMessage}]MSG EX[%{DATA:Exception}]EX"] }
        remove_field => "message"
    }
    date{
        match => ["LogTime","dd/MMM/YYYY:H:m:s Z"]
    }
    }
}
output {
    if [custom_t]=="nlog"{
    elasticsearch {
        hosts => localhost
        manage_template => false
        index => "nlog-%{+YYYY.MM.dd}"
        document_type => "nlog"
    }
    }
}

win2008 安装filebeat，无法执行ps脚本的问题

管理员身份执行cmd，用sc命令安装服务

sc create filebeat displayName= filebeat binPath= "C:\filebeat-5.5.1-windows-x86_64\filebeat.exe -c C:\filebeat-5.5.1-windows-x86_64\filebeat.yml -path.home C:\filebeat-5.5.1-windows-x86_64 -path.data C:\ProgramData\filebeat" start= auto
