I am not 100% sure but I think Cloudflare shows stats of every subdomains as well. Including api.hive.blog, images.hive.blog (in our case, rpc.ecency.com, images.ecency.com), etc. If anyone knows for sure would be interesting to know ways to filter out individual subdomains from Cloudflare analytics...
You can't filter per subdomain iirc, but it definitely will show you stats from all subdomains.
