Blank Alarms and Alarms without messages are observed in Operator Console

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

Hi,

1- When we sort alarms by Device Name this happens:

2- When we open any probe alarms it shows without Alarm message, duration, alarm type and owner:

Environment

Release : 20.3

Component : UIM NAS

Resolution

Performing the following steps resolved the issue:

 

Step 1:

1. Open nas probe GUI and verify the NiS bridge is Activated with the following default settings, else change the to the following default settings:

 

 

Step 2:

1. Deactivate the alarm_enrichment and nas probe

2. Drop each one of the nas tables listed below.
 
DROP TABLE NAS_VERSION;
DROP TABLE NAS_ALARMS;
DROP TABLE NAS_TRANSACTION_SUMMARY;
DROP TABLE NAS_TRANSACTION_LOG;
DROP TABLE NAS_NOTES;
DROP TABLE NAS_ALARM_NOTE;

Some DROP commands may fail if the tables don't exist anymore so you can ignore that as some tables may have changed depending on the Nimsoft/nas version you’re running.

 

Step 3:
 
1. Rename (or move) the following files in the <nimsoft>\probes\serviceas directory to something like .db.old in order to preserve them while setting them aside.
 
   1. transactionlog.db
   2. database.db
   3. nisQueue.db (if it exists)
 

2. Activate the alarm_enrichment and nas probe

When nas is activated, it should recreate those two files, and all of the tables and sync them properly.

 

IMPORTANT NOTE:

Renaming the .db files above will cause the complete "reset" of all alarms in the environment.  If you have integrated your NAS with external systems/ticketing systems/etc please be aware that on the next polling cycle, all of the previous alarms which are still active will come in again, which could cause new/duplicate tickets to be created.  Please be aware of this and take steps to mitigate (such as temporarily disabling such integrations until the alarms regenerate.)

nas alarms are not 'in sync' between UMP (USM) and Infrastructure Manager (IM) (broadcom.com)

Why do some alarms' "count" increase immediately in the alarm console while others don't show the count increasing even when the alarms are suppressed?
