大家好，

经过一番研究，我发现没有机会通过API收集每个保护域的全部快照（独家用法）（我使用5.15.3 AOS）。

由于我每天有很多VM，我如何通过nutanix cmdlet收集此信息并获得该信息？

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>

如果不可能通过API进行更少的更改，可以通过CMDLET获得它。在论坛上的快照上有一个2部分指南，也许您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 ！谢谢回复。

我有3个PD，我尝试了以下脚本：

$ nutanixsnaptotalsize = 0
$ nutanixsnaplist = get-ntnxprotectiondomainsnapshot


foreach（$ nutanixsnap in $ nutanixsnaplist）{
$ nutanixsnaptotalsize = $ nutanixsnaptotalsize + $ nutanixsnap.exclusiveusageinbytes
}
$ nutanixsnaptotalsize

如果我在所有PD上使用Prism控制台连接，我总共看到更多的800 GO GO GO总共使用独家用法，但是通过脚本，我只看到46 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 Element API（V2 One）确实具有此统计数据，在 /protection-domains /{name} endpoint下。响应底部有一个“ usage_stats”对象，上面有“ 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是否具有此统计数据。

在您的第二个问题上，您无法总结一下那样的快照用法。每个快照仅报告独家使用的数据量（即，如果仅删除该快照，那就是免费的空间）。捕获是，通常有多个快照依赖的数据；由于这不是任何一个快照的“独家”，因此它们都不会报告它，但是PD中的总数将反映出来。

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cmdlet，确实在那里！只是有点隐藏。如果您将“ -expandEdoutput”参数添加到“ Get-ntnxProtectionDomain” CMDLET，则会显示出来。这将为您提供您想要的数字：

（get -ntnxprotectiondomain -pdname 。

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>
