你好,

我正在尝试从Prism元素收集一些VM性能数据。

我注意到有些统计数据的历史保存时间不超过5分钟。

例子:
controller_io_bandwidth_kBps与controller_读/写_io_bandwidth_kBps

得到的https:// {IP}: 9440 / PrismGateway /服务/ rest / v1 / vm /{}的vmid /统计/ ?指标=controller_io_bandwidth_kBps&startTimeInUsecs =1589462400000000&intervalInSecs = 300”
“statsSpecificResponses”:(
｛
“成功”:没错,
“消息”:空,
“startTimeInUsecs”:1589462400000000，
“intervalInSecs”:300年,
“指标”:“controller_io_bandwidth_kBps”,
“价值观”:(
8106年,
5500年,

｝

我想我可以计算出缺失的信息:

controller_avg_write_io_size_kbytes x controller_num_write_io

遗憾的是，“controller_avg_write_io_size_kbytes”也不能保存历史记录。

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>

我们面临着同样的问题。指标“controller_read_io_bandwidth_kBps”和“controller_write_io_bandwidth_kBps”只返回最近5分钟的记录。然而，“controller_io_bandwidth_kBps”是在任何时间返回完整的数据集。我们感兴趣的是读取和写入数据分别获取超过5分钟。在Prism元素中，我们可以看到所选磁盘最近4小时的读和写图形，以此为例。我们遗漏了什么?任何帮助都将不胜感激。

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"}}}">

嗨 @PeWu @Aaqib

不确定你是否解决了这个问题，但你有没有试过上面的例子，也使用了“endTimeInUsecs”除了“startTimeInUsecs”?

我问是因为下面的请求返回24小时内的数据，并使用与您的示例中相同的度量(开始时间是2021年1月1日00:00:00，结束时间是1月2日00:00:00)

https:// {{cluster_ip}}: 9440 / PrismGateway /服务/ rest / v1 / vm / {{vm_uuid}} /统计/ ? startTimeInUsecs = 1609419600000000 &endtimeinusecs = 1609419600000000评定= controller_io_bandwidth_kBps&intervalInSecs = 30

此外，还有一些资源可能会有所帮助:

通过API获取虚拟机性能指标(您在这里使用的重点是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 -请注意驼峰式大小写改为蛇式大小写)

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"}}}">
