ESXi 8.0 Update 3i reports "GetKernelStatValues: Detected error while retrieving stats: VSINode(2653): Not found" on Intel Emerald Rapids CPUs

Products

• VMware vSphere ESXi

Issue/Introduction

Symptoms

On ESXi 8.0 Update 3i hosts equipped with Intel 5th Generation Xeon Scalable Processors (Emerald Rapids), you observe the following:

1. Hostd Logs (/var/run/log/hostd.log) are flooded with error messages similar to: Er(163) Hostd[XXXXX]: [Originator@6876 sub=VMkernelStatsProvider(...)] GetKernelStatValues: Detected error while retrieving stats: VSINode(2653): Not found (status=195887107)
2. Boot Logs (/var/run/log/boot.log) contain the following entry: cpuXX:XXXXXXX)MemTier: 581: Unsupported platform for doing performance monitoring
3. Manual VSISH commands for the memory tiering statistics node return "Not found": vsish -e get /statsRegistry/data/MEMTYPE/DRAM/memtypeStatsSet VSISHCmdGetInt():Get failed: Not found

Environment

ESXi 8.0 U3i

Cause

This issue occurs because the Emerald Rapids CPU microarchitecture is not defined as a supported platform for specific memory hardware performance counters in vSphere 8.0 Update 3.

While Emerald Rapids CPUs are supported for general virtualization, the specific performance monitoring nodes (VSINode 2653 ) required for memory tiering statistics are not initialized by the VMkernel on this CPU generation. When the management agents (hostd) attempt to poll these nodes for statistics, the system returns a "Not found" error because the instance was never created.

Resolution

This is a cosmetic reporting issue only.

The error messages do not indicate a failure of the CPU, memory, or VMkernel stability. They strictly impact the availability of specific hardware-level memory performance metrics. There is no impact on production workloads or host stability.

Future Support: Full support for these hardware counters on Emerald Rapids and subsequent CPU generations (e.g., Granite Rapids) is scheduled for future major releases (VCF 9.x / ESXi 9.x).

 

Currently, there is no workaround to enable these counters on ESXi 8.0 Update 3. The error messages in the logs can be safely ignored.

Additional Information

• Impacted CPUs: Intel Xeon Scalable Processors 5th Generation (Emerald Rapids), such as the Gold 6526Y.
• Comparison: Intel 4th Generation (Sapphire Rapids) hosts in the same cluster do not exhibit this behavior as they are supported by the current memory counter definitions in 8.0 U3.
