你好，

我正在尝试从Prism元素中收集一些VM性能数据。

我注意到某些统计数据不会在5分钟内保持历史记录。

例子：
controller_io_bandwidth_kbps vs.控制器_读/写_io_bandwidth_kbps

获取'https：// {ip}：9440/prismgateway/services/rest/v1/vms/{vmid}/stats/？metrics =controller_io_bandwidth_kbps＆starttimeinusecs =1589462400000000＆Intervalinsecs = 300'
“ Statsspefificresponses”：[
{
“成功”：是的，
“消息”：null，
“ starttimeinusecs”：1589462400000000，，，，
“ Intervalinsecs”：300，
“ metric”：“ controler_io_bandwidth_kbps”，
“值”：[
8106，
5500，
8404，
5618，
12793
这是给予的
}
这是给予的
}

获取'https：// {ip}：9440/prismgateway/services/rest/v1/vms/{vmid}/stats/？metrics =controller_read_io_bandwidth_kbps＆starttimeinusecs =1589462400000000＆Intervalinsecs = 300'
{
“ Statsspefificresponses”：[
{
“成功”：是的，
“消息”：null，
“ starttimeinusecs”：1589463510000000，，，，
“ Intervalinsecs”：300，
“ metric”：“ controller_read_io_bandwidth_kbps”，
“值”：[
2038
这是给予的
}
这是给予的
}

获取'https：// {ip}：9440/prismgateway/services/rest/v1/vms/{vmid}/stats/？metrics =controller_write_io_bandwidth_kbps＆starttimeinusecs =1589462400000000＆Intervalinsecs = 300'
{
“ Statsspefificresponses”：[
{
“成功”：是的，
“消息”：null，
“ starttimeinusecs”：1589463540000000，，，，
“ Intervalinsecs”：300，
“ metric”：“ controller_write_io_bandwidth_kbps”，
“值”：[
5891
这是给予的
}
这是给予的
}

我以为我可以从以下方式计算丢失的信息：

controller_avg_write_io_size_kbytes x Contrance_num_write_io

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

这是故意的吗？

问候，

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

我们面临同一问题。指标“ controller_read_io_bandwidth_kbps”和“ controller_write_io_bandwidth_kbps”仅返回最后5分钟的记录。但是，“ controller_io_bandwidth_kbps”在任何持续时间内都返回完整的数据集。我们有兴趣分别获取读和写数据超过5分钟。在Prism元素中，我们可以看到过去4个小时的读取和编写所选磁盘的读图。我们在这里缺少什么？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，但是您是否尝试过上述示例，并且还使用了“ starttimeinusecs”之外的“ endtimeinusecs”？

我之所以问，是因为以下请求在24小时内返回数据，并使用与示例中的数据相同的指标（开始时间是1月1日2021 00:00:00，结束时间是1月2日00:00:00）

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

此外，还有一些资源可能会有所帮助：

通过API获取VM性能指标（当您在此处使用时，专注于Prism API V1）

使用Nutanix Prism API v2.0获取性能统计数据（显示类似的信息，但专门针对Prism API v2.0-请注意，骆驼盒更改为Snake Case）

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>

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"}}}">
