Where is the indexname in the licenseUsage log entries?

Hi, We went from 6.1 to 6.4.1 recently, and noticed that the index that is reporting the license information is now some type of guid, rather than the actual name (See below). How do I get the name for the index? 10-16-2016 23:59:59.375 -0400 INFO LicenseUsage - type=Usage s="udp:5514" st="udp:5514" h="172.25.62.28" o="" idx="default_udp514" i="4B832E19-9B4D-4073-89DB-0B473D1D2623" pool="auto_generated_pool_enterprise" b=8608 poolsz=3886945402880
