Graylog——日志聚合工具中的后起之秀-程序员宅基地

2019独角兽企业重金招聘Python工程师标准>>>

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

输入图片说明

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

不能处理多行日志，比如Mysql慢查询，Tomcat/Jetty应用的Java异常打印
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。
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：

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。
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。
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。
搜索结果高亮显示，就像google一样。
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
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。

mongodb
elasticsearch
graylog-server
graylog-web

以下环境是CentOS 6.6，服务器ip是10.0.0.11，已安装jre-1.7.0-openjdk
