这个问题难倒我了。我打开了一张低优先级的门票，以获取一些官方信息，但我想我应该问这里，看看是否有人有类似的经历:

背景:我们收到棱镜中心的警报，我们的一个集群的CPU即将耗尽。我检查了hypervisor (esxi)，在prism元素和在中央分析，但我没有发现一个问题。然后，我检查了计划，它显示我们运行的CPU很快。

起初我以为最初的加载是扭曲数据,但是当我近距离观察时,我注意到我们当前使用的计划是使用价值在50兆赫,当虚拟机监控程序报告12 ghz(组3),我把所有的其他集群规划数据和他们都有同样的问题,在规划图中，CPU使用情况被过度地报告了。

分析中的图表同意管理程序的观点，但这些图表查看的是使用率百分比，而不是hz。

到底发生了什么事?在如何规划计算CPU使用率方面有bug吗?或者也许我的管理程序报告不足3倍?(似乎不太可能)瞧:

penguindows<\/a>, I think that is the same bug. All you need to do is to upgrade to ncc 3.5 in PC or you can upgrade your PC to 5.5. Both were released yesterday.","className":"post__content__best_answer"}">

\nBackground: we received an alert from prism central that one of our cluster's was going to run out of CPU soon. I checked in the hypervisor (esxi) and in prism element and in central under analysis but i could not find an issue. Then, i checked planning and it shows us running out of CPU very soon.
\n
\nAt first i thought the initial load up was skewing the data, but when i looked closer, i noticed that the value planning was using for our current usage was at 50Ghz, when the hypervisor is reporting 12Ghz (cluster of 3).I pulled all of the other cluster's planning data and all of them have the same problem, CPU usage is being greatly over reported on the planning chart.
\n
\nCharts under analysis agree with the hypervisor, but these are looking at % usage, not hz.
\n
\nWhat gives? is there a bug in how planning is calculating CPU usage? or perhaps my hypervisor is under reporting by a factor of 3? (seems unlikely)looky:

嗨penguindows，

你能告诉我们你的PC和ncc是什么版本吗?我们确实在ncc 3.1.2和PC 5.1.3中发现了一个与你所观察到的非常相似的bug。只是想确认一下。

\nCan you tell us what is the version of your PC and ncc? We did discover a bug in ncc 3.1.2 and PC 5.1.3 that is very similar to what you observed. Just wanted to confirm.","quoteUsername":"harryhy","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

箱号00254576。低优先级，我们没有任何危险。大多数情况下，要么是我读错了数据，要么是计划计算错了(或者是在中间的某个地方)。无论哪种方式，我们目前都没有看到任何有影响的问题，所以不要着急。

harryhyNCC版本为3.1.0,Prism Central版本为5.1.3。所以这可能是同一个问题。
harryhy<\/a> NCC version is 3.1.0 and Prism Central 5.1.3. So this is probably the same issue.","quoteUsername":"penguindows","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

penguindows，我想那是同一只虫子。你所需要做的就是把你的电脑升级到ncc 3.5或者你可以把你的电脑升级到5.5。两人昨日均已获释。

harryhy很好，我会找个时间，几天后再来报告，如果问题解决了就告诉你。
harryhy<\/a> cool, i'll figure out a time for that and report back in a few days to let you know if it resolved.","quoteUsername":"penguindows","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
