As a product manager, I want to know the volume of query traffic that the DCAT endpoint gets, so that I can make a cost/benefit decision on whether to remove this endpoint.

DCAT is a namespace in Blazegraph where we load category trees. We suspect that it is relatively low traffic often enough that the maintenance cost does not make it worth supporting -- removing it will also allow the team to focus on scaling WDQS.

This ticket is to check how many queries we have on this endpoint, and how many queries would be impacted by removing it.

AC:

• determine average number of queries on DCAT (per day/week/month)
