Description

It would be interestintg to have metrics wrt to vanity path lookup and how well the bloom filter performs, such as:

• total number of lookups
• "not founds" because of bloom filter filtering
• "not founds" although bloom filter says "probably contains"
• "hits"

(these metrics would only become active after vanity path init is done)
