VMware NSX manager 'Operations Db Disk Usage High' or 'Operations DB Disk Usage Very High' alarms are triggered

Products

• VMware NSX

Issue/Introduction

• 'Operations Db Disk Usage High' or 'Operations DB Disk Usage Very High' alarms are triggered.
• Login to NSX manager over SSH as root and run the following command:
  

  df -h

  • You see that the /nonconfig partition on the NSX Manager node is 10% or more in the Use% column.

• Run the following command while logged in as root over SSH session to NSX Manager:
  

  find /nonconfig/diskonlycorfutable/idps/ -name LOG -exec ls -lh {} \; 

  • /nonconfig/diskonlycorfutable/idps/*/LOG files on the NSX manager are taking up most of the space comparing to the output of the df -h command.

Environment

VMware NSX-T Data Center 3.2
VMware NSX 4.0
VMware NSX 4.1

Cause

The alarm triggers if the /nonconfig partition space used has grown to 10% or more, due to IDPS log files growing excessively large.
