DRS Rule name not shown for the triggered DRS Recommendation in vCenter UI

Products

• VMware vCenter Server

Issue/Introduction

• VM affinity rules are configured on the cluster in the vCenter.
• DRS is set to Manual mode.
• DRS triggers a Recommendation when a DRS Rule is violated.
• In vCenter > Cluster > Monitor > vSphere DRS > Recommendations, the only columns available are:
  • Priority
  • Recommendation
  • Recommendation ID
  • Reason
• Get-DrsRecommendation command in PowerCLI also provides the output based on the data available in vCenter UI.

Environment

• VMware vCenter Server 7.x
• VMware vCenter Server 8.x

Cause

• This is working as expected by design. Currently DRS Rule name information against the DRS Recommendation is unavailable in vCenter UI or PowerCLI cmdlet.

Resolution

• DRS rule name information can be seen from the /var/log/vmware/vpxd/vpxd.log.
  For example:
  
  • Affinity Rule is created with a name TestRule and is defined for 2 VMs to must run together.
  • If one of the VM is migrated to another ESXi host which violates the rule and DRS recommendation is triggered, below entries can be seen in the vpxd.log:
