本文介紹SpringBoot如何使用Graylog日誌收集。html

1.Graylog介紹

Graylog是一個生產級別的日誌收集系統，集成Mongo和Elasticsearch進行日誌收集。其中Mongo用於存儲Graylog的元數據信息和配置信息，ElasticSearch用於存儲數據。java

架構圖以下：git

生產環境配置圖以下：github

2.安裝Graylog

在官方文檔上推薦了不少種安裝的方式，這裏以docker-compose的方式爲例，進行安裝Graylog，mongo，elasticsearch。web

docker-compose.yml內容以下（這裏是在官網的基礎上改了一下）：spring

version: '2'
services:
  # MongoDB: https://hub.docker.com/_/mongo/
  mongodb:
    image: mongo:3
  # Elasticsearch: https://www.elastic.co/guide/en/elasticsearch/reference/6.6/docker.html
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.6.1
    environment:
      - http.host=0.0.0.0
      - transport.host=localhost
      - network.host=0.0.0.0
      - "ES_JAVA_OPTS=-Xms256m -Xmx256m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    mem_limit: 512m
  # Graylog: https://hub.docker.com/r/graylog/graylog/
  graylog:
    image: graylog/graylog:3.0
    environment:
      # CHANGE ME (must be at least 16 characters)!
      - GRAYLOG_PASSWORD_SECRET=somepasswordpepper
      # Password: admin
      - GRAYLOG_ROOT_PASSWORD_SHA2=8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918
      - GRAYLOG_HTTP_EXTERNAL_URI=http://106.13.35.42:9000/
    links:
      - mongodb:mongo
      - elasticsearch
    depends_on:
      - mongodb
      - elasticsearch
    ports:
      # Graylog web interface and REST API
      - 9000:9000
      # Syslog TCP
      - 1514:1514
      # Syslog UDP
      - 1514:1514/udp
      # GELF TCP
      - 12201:12201
      # GELF UDP
      - 12201:12201/udp
複製代碼

其中106.13.35.42是個人外網ip，本地服務使用127.0.0.1便可。mongodb

其餘方式能夠查看官方文檔，docs.graylog.org/en/3.0/page…docker

3.配置Graylog

在瀏覽器訪問http://ip:9000，如圖：apache

這裏默認用戶名密碼都是admin，進入後如圖所示。瀏覽器

選擇System按鈕中的input，錄入一個輸入源，如圖

這裏以GELF UDP爲例，在圖中位置選擇GELF UDP，選擇完成後點擊Launch new input，如圖

在Node處選擇本身安裝的，剩下的就根據須要填寫便可，如圖

保存完成後如圖，到這裏就已經配置完成了。

4.SpringBoot日誌輸出到Graylog

這裏分別舉例Logback日誌和Log4j2日誌。

4.1 Logback日誌

這裏使用的logback-gelf向Graylog輸出日誌，在github上有對logback-gelf的詳細使用介紹，這裏只是簡單舉例。Github地址：github.com/osiegmar/lo…。

新建項目，加入logback-gelf依賴，pom文件以下：

加入logback日誌配置，新建logback-spring.xml，內容以下:

<configuration>

    <conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter" />
    <conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />
    <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />

        </encoder>
    </appender>

    <appender name="GELF" class="de.siegmar.logbackgelf.GelfUdpAppender">

    </appender>

    <!-- 控制檯輸出日誌級別 -->
    <root level="info">
        <appender-ref ref="GELF" />
        <appender-ref ref="STDOUT" />
    </root>


</configuration>

4.2 Log4j2日誌

log4j2日誌使用的是log4j2-gelf依賴，github上面也有對應的介紹，pom文件以下：

建立log4j2-spring.xml進行配置輸出日誌信息，以下：
