Python 一键巡检服务器资源使用率
一.分析需求与解决方案
1.需要：定期的去统计所有主机的cpu mem disk的使用率。
2.思路方案：1):安装云商的agent，调用api统计。
2):方案是接入自己的监控，查询数据库或者zabbix api统计。
3):通过ansible批量执行脚本来统计。
3.这里使用简单快速的方式，直接查询zabbix数据库的统计趋势值来统计。且windows和Linux的监控指标有个别参数不太一样，所以区分2个脚本，后面可以优化为一个脚本。
4.环境：python3.x ，主要使用包：MySQLdb xlsxwriter,xlwt
二.Zabbix item环境准备
内存使用率计算item
实际内存使用item
实际内存使用率item
实际内存空闲率item
Linux cpu使用率简单统计
windows cpu使用率简单计算
二.代码分享
1.Linux 系统

#zabbix数据库信息：
zdbhost = 'www.csdn.net'
zdbuser = 'python_test'
zdbpass = '123456'
zdbport = 3306
zdbname = 'zabbix'
#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]
'''
注意：keys中的参数要在存在开启状态，才会统计到数据库中，检查下！！！
