win2008r2上的vmware powercli get-stat為空的“字符串”

Question

當我在Windows7上使用vmware powercli從ESXi獲取統計信息時，它給了我響應Wondows7命令：PowerCLI C：\\ temp>

Get-VMHost -Name "hostname.inc.com" | Get-Stat -Stat
 cpu.usage.average  -Start (Get-Date).AddDays(-1) -Finish(Get-Date) -MaxSamples 100

返回輸出

MetricId                Timestamp                          Value Unit     Insta
                                                                          nce
--------                ---------                          ----- ----     -----
cpu.usage.average       31.10.2013 15:40:00                25,03 %
cpu.usage.average       31.10.2013 15:35:00                22,95 %
cpu.usage.average       31.10.2013 15:30:00                23,97 %
...

當從Windows2008r2命令執行時：PowerCLI C：\\ temp>

Get-VMHost -Name "hostname.inc.com" | Get-Stat -Stat
 cpu.usage.average  -Start (Get-Date).AddDays(-1) -Finish(Get-Date) -MaxSamples 100

返回“無”

有趣的-如果在Windows2008r2命令上運行：PowerCLI C：\\ temp>

Get-VMHost -Name "hostname.inc.com" | Get-Stat -Stat
 cpu.usage.average  -Realtime -MaxSamples 100

它給予回應

cpu.usage.average       10/31/2013 9:49:40 AM               9.77 %        30
cpu.usage.average       10/31/2013 9:49:20 AM               8.63 %        30
cpu.usage.average       10/31/2013 9:49:00 AM              12.05 %        30
cpu.usage.average       10/31/2013 9:48:40 AM               11.5 %        30
cpu.usage.average       10/31/2013 9:48:20 AM              14.25 %        30
cpu.usage.average       10/31/2013 9:48:00 AM              11.02 %        30
cpu.usage.average       10/31/2013 9:47:40 AM              11.77 %        30

Answer 1

也許您在Windows 7上使用的Powershell版本正在處理語法錯誤，以解決-Finish(Get-Date)行中的空間不足（應該是-Finish (Get-Date) ）-而Powershell版本在Windows 2008 R2框不處理該錯誤。 因此，當刪除-Start和-Finish開關時，將刪除與-Finish有關的語法錯誤。

它應該是：

Get-VMHost -Name "hostname.inc.com" | Get-Stat -Stat cpu.usage.average -Start (GetDate).AddDays(-1) -Finish (Get-Date) -MaxSamples 100
