It's very important to us that the FQDN is used as the "name" for our CIs. For our purposes, the best source for hostnames in our environment is by far DNS, so trusting other sources such as SSH or WMI will not help.
Setting the value of the "Include domain name in host name" sys_property [glide.discovery.hostname.include_domain] to "true" works most of the time, but we keep getting outliers where only the first part of the hostname is used.
I've noticed that the failures are for devices where the DNS probe brings back results for multiple IP addresses.
Example:
<results probe_time="141" result_code="0">
<result ip_address="XXX.XX.XX.01" result="resolved">
<name>blahblah.mydomain.com</name>
</result>
<result ip_address="XXX.XX.XX.02" result="unresolved">
<name/>
</result>
<result ip_address="XXX.XX.XX.03" result="unresolved">
<name/>
</result>
</results>
In this case, the name of the CI would be "blahblah." This is true even if "XXX.XX.XX.01" is set as the "IP Address" for the CI.
It is populating "blahblah.mydomain.com" in the "Fully qualified domain name" field, so it's not like it can't understand it. It's just not ending up in the main "Name" field.
Is there any way to change this behavior and tell it that if one of many reverse lookups is successful, then to use that result as the name?
