Running the code below will yield ut_domain as ".com" instead of "somethin.shop". It seems like if the subdomain contains a valid TLD string (e.g. .com), then ut_domain is not parsed correctly. A domain "somethingbad.shop" will be parsed correctly as it recognizes .shop as a TLD.
| makeresults | eval domain_full = "something.com.somethin.shop"
| eval list="*" | `ut_parse(domain_full, list)`
Is it a bug? If so, how can we report it? Any workaround you can think of while waiting for bug fix?
The UT toolbox app relies on some .dat files in the $SPLUNKDIR$/etc/apps/utbox/bin/ directory which list the known TLD suffixes. Unfortunately, ".shop" is not listed in them.
To add the ".shop" tld, you can edit the suffix_list_custom.dat file at:
$SPLUNKDIR$/etc/apps/utbox/bin/suffix_list_custom.dat
and add a line containing "shop". A restart is not required to apply this change.
Then try your query again and the ut_domain field value should now be "somethin.shop" as desired.
In fully managed Splunk Cloud context, we don't have access to the file system, so we can't readily edit the custom.dat file. This is a plea to the developers: Could you please update this app to address this need? Thanks!
