Issue/Introduction

The oi_connector is unable to process specific alarms, in the oi_connector log we see messages indicating that the connector is dropping the alarms.

 

" Dropping alarm. CIInformation not found for alarm pds "

 

 

Why the oi_connector is dropping the alarms?

Cause

The above message is an indication that the device doesn't exist in the UIM database

 

By design, "Discovery " probe cache update occurs every 30 minutes, from raw configure > setup > nimbusscan

 

 

You can verify if this is condition as below:

 

1) Open UIM Operator Console (OC) or Infrastructure Management (IM)

Take a note of the alarm ID from

 

2) Open MSSQL

 

3) Verify Alarm ID exist

 

select * from NAS_TRANSACTION_SUMMARY where nimid='<alarm-id>'

 

3) Verify Device exist

 

select * from nas_alarms where nimid = '<alarm_id>'

 

take a note of device name and use it in belo query:

 

select * from cm_device where dev_id = '<dev_name>'

 

for example:

 

 

If the query doesn't return anything then it means that device doesn't' exist yet in the UIM database so the OI_Connector will not be able to process the alarm ingestion request so it will drop it.

Environment

DX Operational Intelligence 20.x or SaaS

DX CA UIM - 20.3.3 + OI_Connector - 1.39

 

Resolution

Reduce the Discovery probe cache update (default 1800 = 30 minutes)

 

For example to set the update to occurs every 5 minutes, set the property = 300
