vSphere 클러스터 또는 리소스 풀을 보고 특정 수준의 메모리 팽창 또는 스와핑을 확인한 경우 어떤 VM이 영향을 받는지 어떻게 식별합니까?일단 찾으면 어떻게 해야 할지 압니다 :)
아래 예에서는 리소스 풀에 65개의 가상 머신이 있습니다. 32GB 미만의 RAM이 있습니다. RAM의 일부가 확장되거나 교체된 VM을 어떻게 식별합니까?
답변1
Powercli는 다음과 같은 작업에 적합합니다.
VM 가져오기 | 여기서 {$_.BalloonedMemory -ne '0'}
여기에 더 많은 예제가 있습니다:

특히 "벌루닝 및 스와핑이 포함된 VM"을 살펴보세요. http://www.getshifting.com/wiki/powerclinotes#resource_pools_with_ballooning_and_swapping
위 링크에서 복사했습니다:
$myCol = @()
foreach($vm in (Get-View -ViewType VirtualMachine | Where-Object `
{$_.Summary.QuickStats.BalloonedMemory -ne "0"})){
$Details = "" | Select-Object VM, `
SwappedMemory ,BalloonedMemory
$Details.VM = $vm.Name
$Details.SwappedMemory = $vm.Summary.QuickStats.SwappedMemory
$Details.BalloonedMemory = $vm.Summary.QuickStats.BalloonedMemory
$myCol += $Details
}
$myCol

이것이 작은 도움이 되기를 바랍니다.
죄송합니다. 이 정보 출력에서 추가 정렬을 수행하고 리소스(호스트, 데이터 저장소, 클러스터)별로 그룹화하기를 원했기 때문에 전체 vCenter에 대해 실행했습니다.

이렇게 하면 더 높은 풍선/스왑 금액에서 더 낮은 금액으로(+ KB를 MB로 변환하려는 경우) 원하는 방식으로 수정하고 정렬할 수 있는 아래 결과가 제공됩니다.
출력을 수정했습니다(호스트 이름을 대체하고 풍선 표시/교환으로 그룹화함).

추가 도움이 필요하시면 오늘은 꽤 늦었기 때문에 내일 좀 더 정신 차리도록 노력하겠습니다.

PS -1:kiloBytes가 API에서 무엇을 의미하는지 잘 모르겠습니다.

이는 이전 스레드에 매우 늦게 추가된 것이지만 이를 파이프라인에 유지하고 각 루프에 대해 방지하는 속도를 더 빠르게 만들 수 있습니다. 이것을 시도해 보십시오:
get-vm | where{ $_.swappedmemory -ne '0'} | get-view | Select Name,@{Name="Swapped”;Expression={$_.summary.quickstats.swappedmemory}},@{Name="Ballooned";Expression={$_.summary.quickstats.balloonedmemory}}
