Description

In service account discovery Azure DNS Zone HD pattern may get identification errors like:

1. MISSING_MATCHING_ATTRIBUTES for cmdb_ci_dns_name

Sample Error:
identification_engine : MISSING_MATCHING_ATTRIBUTES In payload missing minimum set of input values for criterion (matching) attributes from identify rule for table [cmdb_ci_dns_name]. Add these input values in payload item '{"className":"cmdb_ci_dns_name","values":{"discovery_source":"ServiceNow","fqdn":"abcde-system.net","sys_class_name":"cmdb_ci_dns_name"}}'

2. DUPLICATE_PAYLOAD_RECORDS error for cmdb_ci_dns_alias

Sample Error:
identification_engine : DUPLICATE_PAYLOAD_RECORDS Found duplicate items in the payload (index 5 and 6), using className [cmdb_ci_dns_alias] and fields [name]. Remove duplicate items from the payload

The Pattern got empty value for Name and IP from DNS info. We can see the result from step 8 "Parse A Type". The empty name and IP would cause Identification errors in the later steps.

Steps to Reproduce

 

Run cloud resource discovery on Azure Service Account which has DNS info missing IP and name.

Check Pattern debug and logs. The Pattern got empty value for Name and IP from DNS info. We can see the result from step 8 "Parse A Type". The empty name and IP would cause Identification errors in the later steps.

Workaround

Attached new "Azure DNS Zone HD" pattern can be used as workaround before upgrading to a fix target patch.
