大家好,

经过一些研究，我发现没有机会通过API(我在5.15.3 AOS上)收集每个保护域的总快照使用情况(独占使用情况)。

因为我有很多虚拟机每个PD，我如何通过Nutanix Cmdlets收集这些信息，并获得这个每个PD ?

谢谢。

I installed the cmdlets and it is indeed there! Just a bit hidden. It shows up if you add the \u201c-ExpandedOutput\u201d parameter to the \u201cGet-NTNXProtectionDomain\u201d cmdlet. This will give you the number you want in PowerShell:<\/p>

(Get-NTNXProtectionDomain -PdName <PD_NAME_HERE>).usageStats[\"dr.exclusive_snapshot_usage_bytes\"]<\/code><\/pre>

Hello everyone,\u00a0<\/p>

After some research i saw that there is no opportunities to collect Total Snapshot Usage (Exclusive Usage) per Protection Domain through the API (i\u2019m on 5.15.3 AOS).<\/p>

As i have lot of VMs per PD, how can i collect this info through Nutanix Cmdlets and obtain this one per PD\u00a0?\u00a0<\/p>

\u00a0<\/p>

Thanks.<\/p>

如果不能通过API实现，那么通过cmdlet获得它的改变就更少了。在论坛上有一个2部分的快照指南，也许你会发现一些有用的东西:第1部分第2部分

If it\u2019s not possible via API there is even less change to get it by cmdlets. There is a 2 part guide on snapshot here on forum maybe you find something usefull:\u00a0Part 1<\/a>\u00a0part 2<\/a><\/p>","quoteUsername":"Primzy","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好!谢谢你的回复。

我有3个PD，我尝试了以下脚本:

美元NutanixSnapTotalSize = 0
$ NutanixSnapList = Get-NTNXProtectionDomainSnapshot


Foreach($NutanixSnap in $NutanixSnapList) {
$NutanixSnapTotalSize = $NutanixSnapTotalSize + $NutanixSnap.exclusiveUsageInBytes
｝
NutanixSnapTotalSize美元

如果我用prism控制台连接我所有的PD，我看到平均800个更多的快照独占使用，但通过脚本，我看到只有46个Go，我不明白为什么…

Hello ! Thanks for the reply.<\/p>

\u00a0<\/p>

I have 3 PD and i tried the following script :<\/p>

$NutanixSnapTotalSize = 0
$NutanixSnapList = Get-NTNXProtectionDomainSnapshot<\/p>


Foreach($NutanixSnap in $NutanixSnapList) {\u00a0
$NutanixSnapTotalSize = $NutanixSnapTotalSize + $NutanixSnap.exclusiveUsageInBytes
}
$NutanixSnapTotalSize<\/p>

\u00a0<\/p>

If i connect on prism console for all my PD i saw more in average 800 Go on Snapshot Exclusive Usage in Total but by script i saw only 46 Go i don\u2019t understand why...<\/p>","quoteUsername":"LDams","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

Prism元素API (v2)确实有这个属性，在/protection-domains/{name}端点下。在响应的底部有一个“usage_stats”对象，它有“dr.exclusive_snapshot_usage_bytes”

https://www.nutanix.dev/reference/prism_element/v2/api/protection-domains/get-protection-domains-name-getprotectiondomainbyname

我不确定cmdlet是否有这个数据。

关于第二个问题，您不能这样总结快照的使用。每个快照只报告它所独占使用的数据量(例如，如果你只删除了那个快照，那就是它所释放的空间)。问题是，通常有多个快照依赖的数据;因为这不是“独占”于任何一个快照，他们都不会报告它，但PD中的总数将反映它。

The Prism Element API (the v2 one) does have this stat, under the \/protection-domains\/{name} endpoint. There\u2019s a \u201cusage_stats\u201d object towards the bottom of the response that has \u201cdr.exclusive_snapshot_usage_bytes\u201d<\/p>

https:\/\/www.nutanix.dev\/reference\/prism_element\/v2\/api\/protection-domains\/get-protection-domains-name-getprotectiondomainbyname<\/a><\/p>

I\u2019m not sure if the cmdlets have this stat though.<\/p>

On your second question, you can\u2019t sum up snapshot usage like that. Each snapshot only reports the amount of data it\u2019s exclusively using (i.e. if you deleted only that snapshot, that\u2019s how much space it would free). The catch is that there\u2019s usually data that multiple snapshots are relying on; since that\u2019s not \u201cexclusive\u201d to any one snapshot, none of them will report it, but the total number in the PD will reflect it.<\/p>","quoteUsername":"JacksonWrath1607","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

跟进:

我安装了cmdlets，它确实在那里!只是有点隐蔽。如果您将“-ExpandedOutput”参数添加到“Get-NTNXProtectionDomain”cmdlet中，它就会显示出来。这将在PowerShell中给出你想要的数字:

(Get-NTNXProtectionDomain -PdName < PD_NAME_HERE >) .usageStats(“dr.exclusive_snapshot_usage_bytes”)

Follow up:<\/p>

I installed the cmdlets and it is indeed there! Just a bit hidden. It shows up if you add the \u201c-ExpandedOutput\u201d parameter to the \u201cGet-NTNXProtectionDomain\u201d cmdlet. This will give you the number you want in PowerShell:<\/p>

(Get-NTNXProtectionDomain -PdName <PD_NAME_HERE>).usageStats[\"dr.exclusive_snapshot_usage_bytes\"]<\/code><\/pre>

很多谢谢!

我今天会检查并回复我的情况:)。
