豆子今天登陆Vsphere VCenter的时候,无意中发现有DataStore的警报信息,个别DataStore的使用空间超过90%了,需要清空一下SAN Volume的Snapshot。这个是运维常见的问题,那么顺便就用PowerShell写个脚本,定期检查发送邮件好了。

脚本本身很容易,但是我想让他尽量的美观一些。

之前我写过一个博文可以自定义sytle的样式 http://beanxyz.blog.51cto.com/5570417/1786712, 不过现在看起来有些麻烦,还是觉得找找如果有比较好看的现成的css文件可以直接调用就好了。

上网搜了搜 table有哪些现成的css模板,随便找了一个https://codepen.io/anon/pen/vJmLWL,看着还成

下载他的css下来

PowerShell 发送美观的Vsphere DataStore警报

下载的css文件,保存在C:\tmp 目录

下面是正式的脚本,Set-CellColor也是别人写好的现成的,我直接拿来用了,主要功能是根据条件来更改html文件table的格子的颜色,比如某个值大于警报线就标记为红色等等。脚本中间加载Vsphere SnapIn,查询datastore的状态,最后把结果转换为html,通过Office365发送邮件出去
