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?


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.

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
