Have you applied the Update 1 package for ESXi 4.1 (and all later patches)? There was a thread about this exact issue on the VMTN a while back, some found that appling U1 fixed the issue.<br />

ESXi 4.1 on IBM metal with vCenter on a Server08 R2/SQLEE VM hosted on one of the hosts.<br />
<br />
My vcenter --&gt; host --&gt; performance --&gt; overview --&gt; network chart show 0kbps constantly. &nbsp;If I go into the Advanced mode, I see traffic on the NIC's.<br />
<br />
The same is true with the Memory (MBps) chart. &nbsp;The other charts all have data.<br />
<br />
I saw a post talking about altering the vcenter db to change the field type on some history tables and recreating a couple of views - I did that and have waited a day with no changes in those 2 charts.<br />
<br />
Any thoughts?

vcenter performance chart network has no data

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.

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.
