Graylog——日志聚合工具中的后起之秀

前端之家收集整理的这篇文章主要介绍了Graylog——日志聚合工具中的后起之秀前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

日志管理工具总览

先看看 推荐!国外程序员整理的系统管理员资源大全 中,国外程序员整理的日志聚合工具的列表:

日志管理工具:收集,解析,可视化

  • Elasticsearch - 一个基于Lucene的文档存储,主要用于日志索引、存储和分析。
  • Fluentd - 日志收集和发出
  • Flume -分布式日志收集和聚合系统
  • Graylog2 -具有报警选项的可插入日志和事件分析服务器
  • Heka -流处理系统,可用于日志聚合
  • Kibana - 可视化日志和时间戳数据
  • Logstash -管理事件和日志的工具
  • Octopussy -日志管理解决方案(可视化/报警/报告)

Graylog与ELK方案的对比

  • ELK: Logstash -> Elasticsearch -> Kibana
  • Graylog: Graylog Collector -> Graylog Server(封装Elasticsearch) -> Graylog Web

之前试过Flunted + Elasticsearch + Kibana的方案,发现有几个缺点:

  1. 不能处理多行日志,比如MysqL查询,Tomcat/Jetty应用的Java异常打印
  2. 不能保留原始日志,只能把原始日志分字段保存,这样搜索日志结果是一堆Json格式文本,无法阅读。
  3. 不复合正则表达式匹配的日志行,被全部丢弃。

本着解决以上3个缺点的原则,再次寻找替代方案。 首先找到了商业日志工具Splunk,号称日志界的Google,意思是全文搜索日志的能力,不光能解决以上3个缺点,还提供搜索单词高亮显示,不同错误级别日志标色等吸引人的特性,但是免费版有500M限制,付费版据说要3万美刀,只能放弃,继续寻找。 最后找到了Graylog,第一眼看到Graylog,只是系统日志syslog的采集工具,一点也没吸引到我。但后来深入了解后,才发现Graylog简直就是开源版的Splunk。 我自己总结的Graylog吸引人的地方:

  1. 一体化方案,安装方便,不像ELK有3个独立系统间的集成问题。
  2. 采集原始日志,并可以事后再添加字段,比如http_status_code,response_time等等。
  3. 自己开发采集日志的脚本,并用curl/nc发送到Graylog Server,发送格式是自定义的GELF,Flunted和Logstash都有相应的输出GELF消息的插件。自己开发带来很大的自由度。实际上只需要用inotifywait监控日志的modify事件,并把日志的新增行用curl/netcat发送到Graylog Server就可。
  4. 搜索结果高亮显示,就像google一样。
  5. 搜索语法简单,比如: source:mongo AND reponse_time_ms:>5000,避免直接输入elasticsearch搜索json语法
  6. 搜索条件可以导出为elasticsearch的搜索json文本,方便直接开发调用elasticsearch rest api的搜索脚本。

浏览器中输入url: http://10.0.0.11:9000/ 可以进入graylog登录页, 管理员帐号/密码: admin/123456

  1. 添加日志收集器

以admin登录http://10.0.0.11:9000/

4.1 进入 System > Inputs > Inputs in Cluster > Raw/Plaintext TCP | Launch new input 取名"tcp 5555" 完成创建

任何安装nc的Linux机器上执行:

echo `date` | nc 10.0.0.11 5555

浏览器的http://10.0.0.11:9000/登录后首页,点击第三行绿色搜索按钮,看到一条新消息:

Timestamp Source Message 
2015-05-22 08:49:15.280	10.0.0.157	2015年 05月 22日 星期五 16:48:28 CST

说明安装已成功!!

4.2 进入 System > Inputs > Inputs in Cluster > GELF HTTP | Launch new input 取名"http 12201" 完成创建 任何安装curl的Linux机器上执行:

curl -XPOST http://10.0.0.11:12201/gelf -p0 -d '{"short_message":"Hello there","host":"example.org","facility":"test","_foo":"bar"}'

浏览器的http://10.0.0.11:9000/登录后首页,点击第三行绿色搜索按钮,看到一条新消息:

Timestamp Source Message 
2015-05-22 08:49:15.280	10.0.0.157	Hello there

说明GELF HTTP Input设置成功!!

  1. 时区和高亮设置

[root@logserver ~]# vi /etc/graylog/server/server.conf
---
30 root_timezone = Asia/Shanghai
---
[root@logserver ~]# /etc/init.d/graylog-server restart

其他帐号的默认时区:

[root@logserver ~]# vi /etc/graylog/web/web.conf
---
18 timezone="Asia/Shanghai"
---
[root@logserver ~]# /etc/init.d/graylog-web restart

允许查询结果高亮:

[root@logserver ~]# lib]$ sudo /etc/init.d/graylog-web start
  1. 移动数据目录

移动elasticsearch的数据目录
[root@logserver ~]# sudo /etc/init.d/elasticsearch stop
[root@logserver ~]# sudo cp -rp /var/lib/elasticsearch/ /data/
[root@logserver ~]# sudo vi /etc/sysconfig/elasticsearch
+16 DATA_DIR=/data/elasticsearch
[root@logserver ~]# sudo /etc/init.d/elasticsearch start

移动mongo的数据目录
[root@logserver ~]# sudo /etc/init.d/mongod stop
[root@logserver ~]# sudo cp -rp /var/lib/mongo /data/
[root@logserver ~]# sudo vi /etc/mongod.conf
---
13 dbpath=/var/lib/mongo
->
13 dbpath=/data/mongo
---
[mtagent@access2 ~]$ sudo /etc/init.d/mongod start

发送日志到Graylog服务器

使用http协议发送:

http://docs.graylog.org/en/1.1/pages/sending_data.html#gelf-via-http

curl -XPOST http://graylog.example.org:12202/gelf -p0 -d '{"short_message":"Hello there","_foo":"bar"}'

使用tcp协议发送

http://docs.graylog.org/en/1.1/pages/sending_data.html#raw-plaintext-inputs

echo "hello,graylog" | nc graylog.example.org 5555
