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
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
#修改颜色块的设定 Function Set-CellColor { [CmdletBinding()] Param ( [Parameter(Mandatory,Position=0)] [string]$Property, [Parameter(Mandatory,Position=1)] [string]$Color, [Parameter(Mandatory,ValueFromPipeline)] [Object[]]$InputObject, [Parameter(Mandatory)] [string]$Filter, [switch]$Row ) Begin { Write-Verbose "$(Get-Date): Function Set-CellColor begins" If ($Filter) { If ($Filter.ToUpper().IndexOf($Property.ToUpper()) -ge 0) { $Filter = $Filter.ToUpper().Replace($Property.ToUpper(),"`$Value") Try { [scriptblock]$Filter = [scriptblock]::Create($Filter) } Catch { Write-Warning "$(Get-Date): ""$Filter"" caused an error, stopping script!" Write-Warning $Error[0] Exit } } Else { Write-Warning "Could not locate $Property in the Filter, which is required.

我收到的邮件效果
最后添加脚本到task scheduler里面让他每日自动运行就行了
