NSX-T slow API/UI response time

Products

• VMware NSX

Issue/Introduction

Symptoms:

• Slow response times are seen on one of the Manager node. Likely the one attached to the VIP.
  • Run a REST API call using Postman (Or equivalent) to each Manager nodes and to the VIP, as example: GET https://<nsx-mgr>/api/v1/transport-nodes
  • The API response time is higher (seconds instead of few ms) toward the VIP and one of the Manager.
• Restarting the affected nodes or restarting the http service ("restart service http") will fix the slow API response.
• The issue is reported after few days on another Manager node (Typically, the one attached to the VIP).
• There is an important API load toward the Manager nodes.
