大家好！
我们为更新的Linux管理员课程开辟了一套新课程：所有相同的新老师，一个动态程序和有趣的讨论。 好吧，与此同时，我们分享了一位老师的真实案例Alexey Tsykunov的有趣笔记。
走吧
挑战赛
您必须配置对DELL MD36XX磁盘存储上的负载的监视。
有一个问题-架子不知道如何通过snmp发送数据。 顺便说一下，在IBM，HP和其他供应商的存储设施中也发现了类似的问题。
环境
供应商自己提供客户端软件。 所谓StorageManager的。 其中一些仅适用于Windows，但最近出现在Linux下。 就我而言，该软件安装在Linux下，并包含控制台实用程序SMcli。 使用SMcli，您可以将统计信息收集到文件中：
SMcli -n StorageName -S -quick -c "save storageArray performanceStats file=\\"/var/log/md36xx.stat\\";"
它看起来像这样

决策选项
可以解析此信息并将其发送到zabbix，并且有几种发送选项
Zabbix代理和UserParameter，您可以在其中绘制每个感兴趣的参数，例如：
UserParameter = dell.md.discovery, /path/script_discovery UserParameter = dell.md.totalio[*], /path/script2 $1 UserParameter = dell.md.currmb[*], /path/script3 $1
Zabbix_sender，可以通过脚本调用一次发送所有参数。 这是我选择的选项。
zabbix中的设置
在zabbix中，您需要配置一个新主机并在其中创建发现规则
在其中指定一个过滤器：
并添加项目原型
这里更详细地说明了原型的规定方式：
发送到Zabbix
数据可以通过zabbix_sender -i <key_value_file>发送
档案格式：
HOST key value
作为值，您可以采用以下格式传递json以进行发现：
{ 'data' :[ {'{#MDDEV}': 'drive1'}, {'{#MDDEV}': 'drive1'}, ] }
{#MDDEV}是其中的宏，通过它可以找到要进行统计的设备/驱动器的名称。
动作的总算法如下：
-我们通过SMcli删除统计信息，保存到文件中；
-解析收到的文件；
-为zabbix_sende r生成一个文件。
所有这些都可以通过bash脚本来实现。 但是在我看来，这是实现一个Python脚本的最简单方法，然后每分钟从头开始调用它。 仅zabbix中的发送模块出现了困难。 它在2.7和3.6下安装，但仅在3.6下启动。
该脚本可以在GitHub上获取
与往常一样，我们在这里或在公开课程中等待问题和评论。
