Wrong Host name details in the alerts in SOI
Release : 4.2
Component : Service Operations Insight (SOI) Manager
run the following SQL queries against the UIM DB to see the info for the missing CI.
select * from CM_CONFIGURATION_ITEM where ci_name like '%<hostname>%'
select * from CM_COMPUTER_SYSTEM where name like '%<hostname>%>
if the result show no entry.
since it's not in the UIM DB, the UIM connector will not get the info to create a CI in SOI, instead the UIM connector associated those alerts with the Primary Hub name.
Please work with the UIM team to find out why that CI is missing from the DB.
