question about the nas message "nas: maint: dev_id '(dev_id)' from '(hub/ip)' is NOT in maintenance."

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

What does this message indicate? And why would it be repeating thousands of times?

nas: maint: dev_id '<EXAMPLE>' from '<DEVICE ADDRESS/nas>' '<IP Address>' is NOT in maintenance.

 

Environment

• Release: 20.4

Cause

• Alarm flood

Resolution

This message is logged at loglevel 3 for each alarm that comes in as the NAS probe checks the maintenance schedules to see if the alarm should be suppressed.

If you see this message repeating over and over with different dev_id's this is normal, and an indicator that you have high alarm traffic.

If you see the same dev_id over and over, it indicates that the device is sending an alarm flood.

You can determine what device this is with the following SQL Query vs the UIM database:

   select * from cm_device where dev_id = '<dev_id_here>';
