Solution 1

Take a look at the alert object and notice the assignedHosts entries

udm monitoring/alert list --filter cn=UNIVENTION_KPASSWDD

You can remove those assignedHosts entries with udm. For example:

udm monitoring/alert modify --dn cn=UNIVENTION_KPASSWDD,cn=monitoring,$(ucr get ldap/base) --remove assignedHosts=cn=primary,cn=dc,cn=computers,$(ucr get ldap/base)
