你好，

我正在尝试从棱镜元素收集一些VM性能数据。

我注意到一些统计数据不会超过5分钟。

例子：
Controller_IO_BANDWIDTH_KBPS与Controller_读/写_io_BandWidth_kbps.

获取'https：// {ip}：9440 / prismgateway / services / rest / v1 / vms / {vmid} / stats /？metrics =controller_io_bandwidth_kbps.＆starttimeinusecs =1589462400000000＆internalinsecs = 300'
“statspecificresponses”：[
{
“成功”：真实，
“消息”：null，
“starttimeinusecs”：1589462400000000那
“internalinsecs”：300，
“公制”：“controller_io_bandwidth_kbps”，
“值”：[
8106，
5500，
8404，
5618，
12793
]
}
]
}

获取'https：// {ip}：9440 / prismgateway / services / rest / v1 / vms / {vmid} / stats /？metrics =controller_read_io_bandwidth_kbps.＆starttimeinusecs =1589462400000000＆internalinsecs = 300'
{
“statspecificresponses”：[
{
“成功”：真实，
“消息”：null，
“starttimeinusecs”：1589463510000000那
“internalinsecs”：300，
“公制”：“controller_read_io_bandwidth_kbps”，
“值”：[
2038.
]
}
]
}

获取'https：// {ip}：9440 / prismgateway / services / rest / v1 / vms / {vmid} / stats /？metrics =Controller_Write_io_BandWidth_kbps.＆starttimeinusecs =1589462400000000＆internalinsecs = 300'
{
“statspecificresponses”：[
{
“成功”：真实，
“消息”：null，
“starttimeinusecs”：1589463540000000那
“internalinsecs”：300，
“公制”：“controller_write_io_bandwidth_kbps”，
“值”：[
5891
]
}
]
}

我以为我可以计算缺失的信息：

controller_avg_write_io_size_kbytes x controller_num_write_io.

可悲的是，“controller_avg_write_io_size_kbytes”也不会保留历史记录。

这是故意的吗？

问候，

Hello,<\/p>

I am trying to collect some VM performance data from Prism element.<\/p>

I have noticed that some stats do not keep history for more than 5 minutes.<\/p>

I thought I could calculate missing information from:<\/p>

controller_avg_write_io_size_kbytes\u00a0\u00a0 x\u00a0\u00a0 controller_num_write_io<\/p>

Sadly, \u201ccontroller_avg_write_io_size_kbytes\u201c\u00a0 does not keep history either.<\/p>

\u00a0<\/p>

Is this intentional?<\/p>

\u00a0<\/p>

Regards,<\/p>

我们面临同样的问题。度量标准“Controller_Read_io_BandWidth_kbps”和“Controller_Write_IO_BANDWidth_kbps”只返回最后5分钟的记录。但是，“Controller_IO_BANDWIDTH_KBPS”返回完整的数据集任何持续时间。我们有兴趣在5分钟内单独获取读写数据。在棱镜元素中，我们可以看到最后4小时等所选磁盘的读写图。我们在这里遗漏了什么？任何帮助将非常感激。

We are facing the same issue. Metrics \u201ccontroller_read_io_bandwidth_kBps\u201d and \u201ccontroller_write_io_bandwidth_kBps\u201d only return\u00a0last 5 minutes' records. However, \u201ccontroller_io_bandwidth_kBps\u201d is returning complete dataset for any duration. We are interested in fetching both Read and Write data separately\u00a0for more than 5 minutes. In Prism Element we can see both Read and Write graphs of the selected Disk for the last 4\u00a0hours and so on. What are we missing here?. Any help would be much appreciated.<\/p>","quoteUsername":"Aaqib","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

你好 @Pewu. @aaqib.

不确定是否解决了此问题，但您还尝试了上面的示例，还要除了“StarttimeInusecs”之外使用“EndtimeInusecs”？

我问，因为以下请求在24小时内返回数据，并使用与示例中的一个相同的度量（开始时间为1月1日2021 00:00:00：00:00:00：00:00:00：00:00:00

https：// {{cluster_ip}}：9440 / prismgateway / services / rest / v1 / vms / {{vm_uuid}} / stats / starttimeinusecs = 1609419600000000和metrics = controller_io_bandwidth_kbps＆Internalinsecs = 30

此外，还有几个可能有帮助的资源：

通过API获取VM性能指标（在您使用的情况下，专注于棱镜API V1）

使用Nutanix Prism API V2.0获取性能统计数据（显示类似的信息，但专门用于PRISM API V2.0 - 请注意骆驼盒变为蛇盒）

Hi @PeWu<\/user-mention>@Aaqib<\/user-mention>\u00a0<\/p>

Not sure if you solved this, but have you tried the above examples and also used\u00a0\u201cendTimeInUsecs\u201d in addition to \u201cstartTimeInUsecs\u201d?<\/p>

I ask because the following request returns data over a 24 hour\u00a0period and uses the same metric as the one in your examples (start time is Jan 1st 2021 00:00:00, end time is Jan 2nd 00:00:00)<\/p>

https:\/\/{{cluster_ip}}:9440\/PrismGateway\/services\/rest\/v1\/vms\/{{vm_uuid}}\/stats\/?startTimeInUsecs=1609419600000000&endTimeInUsecs=1609506000000000&metrics=controller_io_bandwidth_kBps&intervalInSecs=30<\/p>

In addition, there are a couple of resources that may help:<\/p>

Getting VM Performance Metrics via API<\/a>\u00a0(focuses on Prism API v1 as you\u2019re using here)<\/p>

Getting performance stats with the Nutanix Prism API v2.0<\/a>\u00a0(shows similar info but specifically for Prism API v2.0 - please note the camel case change to snake case)<\/p>","quoteUsername":"ChrisRNutanix","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
