We need to identify the set of metrics to understand the storage workloads of Tendermint. The metrics should help us identify:

• The access patterns (sequential / random access)
• How often the data is read/written
• Who reads/writes the data
• Is the data accessed by multiple components or just one.

Open questions: Do we want information on which Tendermint Blockstore / StateStore method call triggered the access or is read/write/delete count and timing enough?

Draft implementation: #9774

DoD

• Set of candidate metrics is established, discussed and well understood.
• The identified metrics are added into the Tendermint codebase.
