Products

• VMware NSX

Issue/Introduction

• You are running NSX Application Platform (NAPP) 3.2.1 or 4.0.1.
• The NSX-T UI displays alarms indicating:
  • Feature: NSX Application Platform Health
  • Event Type: Platform Disk Usage Very High
  • Severity: Critical
• With text:

The disk usage of Platform Services service is above the very high threshold value of 90%.

• Alert seen in NSX-T UI:

• On the Kubernetes platform where NAPP is deployed, when we check the cluster-api pod for space:

napp-k -n nsxi-platform exec -it `napp-k get pods -n nsxi-platform | grep cluster | cut -d ' ' -f 1` -c cluster-api bash
df -h
We see the directory storing the support bundle is very high or 100%

Cause

The logrotate feature is not quick enough to rotate the logs and thus the files grow to quickly, causing space issues.
