NSX UI reports Compute Manager Capacity Threshold Alarm "Maximum Capacity Threshold "

Products

• VMware NSX

Issue/Introduction

• A capacity alarm with event type Minimum Capacity Threshold is reported in the NSX UI.
• Error descriptions:
  • The number of objects defined in the system for Compute Managers has reached 2 which is above the minimum capacity threshold of 70.0%. Maximum number of Compute Managers supported is 2.

• • The number of objects defined in the system for Compute Managers has reached 3 which is above the maximum capacity threshold of 100.0%. Maximum number of Compute Managers supported is 2.

Environment

VMware NSX-T 3.2

VMware NSX

Cause

In NSX-T 3.2 and later releases, the NSX manager form factor determines how many Compute Managers are supported:

• Medium NSX-T Managers support up to 2 Compute Managers
• Large NSX-T Managers support up to 16 Compute Managers

Resolution

• Ensure the number of compute managers does not exceed the maximum limit supported for the current NSX sizing configuration.
  • Reference to "Configuration maximums of NSX".
• To support additional compute managers, either resize NSX manager nodes (preferred) or remove additional compute managers added. For resizing instructions, refer to the 'Resize NSX-T Manager 3.x/Resize NSX Manager 4.x' technical documentation.
• Note: There is a known issue in NSX-T Manager version 3.2.x (prior to 3.2.3) when using the Medium form-factor (6 vCPU, 24 GB RAM). While this configuration is designed to support up to two Compute Managers as per Configmax guidelines, the capacity dashboard incorrectly displays the count as one. This is a false positive within the dashboard's framework. Refer KB: False positive 'Compute Manager Minimum Capacity Threshold' Alarm for 'Medium' form-factor NSX-T Managers.
