Problem:
------------
In my SOI console I can see lot of alerts from Nimsoft (UIM) showing Name: Unknown and Class: Entity as per below screenshot
Solution:
-----------
1. Gather 'Source Alert ID' (nimid in Nimsoft (UIM)) for this alert.
I am considering example for nimdi as BZ22306757-19698
2. using this ID run following query against nimsoft (UIM) database
select * from CM_COMPUTER_SYSTEM where name in (select hostname from NAS_ALARMS where nimid like '%BZ22306757-19698%')
3. If result returns blank as below screenshot then its a problem with Nimsoft (UIM) and as CI name is not present in Nimsoft (UIM) db, connector has no CI to publish to SOI.
Nimsoft (UIM) connector gather CI information from CM_COMPUTER_SYSTEM table and publish to SOI and if CI is not populated to this table connector can not publish CI to SOI and when this CI is alerted, alert is send to SOI but as SOI do not have CI to attach this alert with this alert will shown as Name: Unknown and Class: Entity
This CI is published to CM_COMPUTER_SYSTEM table bu discovery probe, hence this issue need to be work from Nimsoft (UIM) side.
