Zabbix 使用规范和生成报表

标签:zabbix,系统运维 发布于 2016-12-31 12:03:12

参考视频内容:http://www.roncoo.com/course/view/fb3050a5b34b42f39ccad83ebebc89c1


一、软件版本

操作系统:CentOS-6.5-x86_64

zabbix版本:3.0.3

 

二、zabbix标准:

 

1、  主机命名规范:

 BJ-monitor-h-zabbix-01

**命名规范是,我们看一台主机能够知道主机位于哪里:BJ;做什么的:monitor;虚拟化还是实体机:h;跑什么服务:zabbix  第几台:01

 

2、  一台主机直接关联多个模板:不用创建多个分组(可以结合CMDB平台)

Memcached :192.168.10.100

Php

Linux:192.168.10.100

多个模板:192.168.10.100  linux,memcached,port,partion

 

3、  自定义key开启:Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf

方便识别服务名和增删key。也方便结合saltstack等批量工具。

 

4、  使用模板继承(linux):

比如系统我们创建有,php,nginx,mysql等模板,所有服务都是基于linux服务器,那么这三个模板我们可以继承linux os模板。

 

三、zabbix os模板报表出图:

[root@BJ-mail-h-mail-01 alertscripts]# cat zabbix_report.py

#!/usr/bin/python

#coding:utf-8

 

import MySQLdb

import time,datetime

 

#zabbix数据库信息:

zdbhost = 'localhost'

zdbuser = 'zabbix'

zdbpass = 'zabbix'

zdbport = 3306

zdbname = 'zabbix'

 

#生成文件名称:

xlsfilename = 'damo.xls'

 

#需要查询的key列表 [名称,表名,key值,取值,格式化,数据整除处理]

keys = [

    ['CPU平均空闲值','trends','system.cpu.util[,idle]','avg','%.2f',1],

    ['CPU最小空闲值','trends','system.cpu.util[,idle]','min','%.2f',1],

    ['CPU5分钟负载','trends','system.cpu.load[percpu,avg5]','avg','%.2f',1],

    ['物理内存大小(单位G)','trends_uint','vm.memory.size[total]','avg','',1048576000],

    ['根分区总大小(单位G)','trends_uint','vfs.fs.size[/,total]','avg','',1073741824],
