Issue/Introduction:

  • The NqMetricD process on the Multi-Port Monitor is stopping and starting
  • Data is no longer being processed by the Multi-Port Monitor
  • ADA is no longer receiving data in the GUI
  • The following error is occurring in the nqMetricReader_XXXXXXXX.log

Cause:

A duplicate entry for a server/subnet/network has been configured in ADA and is being synced down to the Multi-Port Monitor. The nqMetricD process is unable to handle this duplicate entry, ceases processing data, and crashes.

Environment:

CentOS

Resolution:

To remedy the issue:

  • Log into the ADA console via RDP
  • Open a command prompt
  • 'myqsql'
  • 'use super'
  • Run through the attached .txt file
