[MySQL] zabbix二次开发之从mysql取值在运维平台js图表展现

数据库 数据库 发布于：2021-07-04 10:30 | 阅读数：312 | 评论：0

　　前沿：
　　     集群控制平台已经要慢慢的灰度上线了，出问题的时候，才找点bug，时间有点空闲。正好看了下zabbix的数据库，产生了自己想做一套能更好的展现zabbix的页面。
　　

　　更多内容请到我的个人的博客站点，blog.xiaorui.cc
　　

　　    zabbix的强点大家都感觉或者用出感觉了，确实很是方便。曾经的我，跟着公司的团队开发过一套不小的监控系统，看过我博客的人应该留意到那个用redis mongodb，后期改用golang，0mq支撑业务的监控平台。
　　     其实对比起来，我个人还是喜欢zabbix，虽然和团队一起很爽，爽也只是设计一套监控平台框框，里面的东西填写起来那可真是吐血。。。 随着看zabbix的文档深入，越发的觉得，zabbix做的真不错。   但是大家有没有觉得，对于不熟系zabbix的人，让他一下在看zabbix的数据，绝对是有点发蒙，他数据展现的有点不清不白的，当然有过配置和运维经验的人，一眼就能看出哪是哪里。

　　

　　旁边cdn部门在讨论东西的时候，我发现他们的那个报表不直观，而且不高端。。。
　　

　　

　　    对于zabbix，我用的最多的反而是api，在上个公司做了一个简练的针对zabbix的api接口，可以迅速的增删改查主机，虽然时不时的抽风，但是那绝对我自己对zabbix理解的问题。
　　

　　我期待的样子
　　1.   权限用公司的权限管理系统，集中单点登录。
　　2.   登录后输入ip地址，可以看到这个ip地址所属的情况，比如内存，cpu，流量等等。
　　3.   根据业务线做好分组，这样dba组的人，一登录就可以看到dba所属的服务器状况。
　　4.   数据库采用zabbix的从库，这样就能很好的免除了压力。
　　

　　

　　当然写完前三个大需求就成一个项目了，目标定的是很远，但是精力是有限。
　　我们可以先来个简单了，从数据库里面取出item监控项的时间和值，然后用前端的图表进行画图。
　　

　　
　　我们首先要从mysql里面取值，Zabbix中存储历史数据的表是以history开头的，目前zabbix 2.06 中主要有一下几张表。
　　>>>>>history              Numeric(float)
　　 >>>>>history_log           -log
　　 >>>>>history_str           -Character
　　 >>>>>history_text          -text
　　 >>>>>history_uint          -Numeric(unsigned)
　　

　　通过数据库可以看到这个值的 item 时间 value ns

　　我们看下zabbix的针对eth0监控的图表
　　 DSC0001.jpg
　　

　　流量的统计，这里只是简单的把数据塞到了jinja2的模板里面，然后用highcharts画图的 。

　　我们再来看看zabbix的几个主要的表：
　　一看就懂，在咱们创建主机的那几个选项。。。要留意下hostid，这个hostid在其他表做了数据字段的关联。
