Hi Andrew,<br />
are you referring to this?<br />
<a href="https://filedb.experts-exchange.com/incoming/2020/04_w17/1450759/disk.JPG" target="_blank" title="disk.JPG (77 KB)"><img alt="disk.JPG" class="file-block lazyload" style="max-width: 800px;" data-src="https://filedb.experts-exchange.com/incoming/2020/04_w17/800_1450759/disk.JPG" /></a><br />
It seems I am only able to watch real-time data, if I try to see past data, I get message:<br />
<br />
Statistics level 2 is required to collect this data. <br />
<br />
thank you

Hi Andrew,<br />
thank you very much. My understanding is that there is no way to enable such statistic data for one specific VM, correct?

it will display info for top 10.<br />
<br />
what are you trying to research ?

I mean: in order to get IOPS for a specific VM (just one) I need to raise statistics level to &quot;2&quot; for entire cluster, right?<br />
So I am going to collect data for every VM in my cluster.<br />
I just wondering if this can cause disk issue on my storage (I manage &gt;&nbsp;100 VMs)

This is just stats collection in the Center Server database.

Hi, I am using ESXi 6.7<br />
How can I collect historical IOPS of a specific VM?<br />
Thank you

Datastore IO data about specific VM

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
