Some chain-related metrics are difficult to expose via ckb node itself. Luckily, we can extract these chain-related metrics via analyzing corresponding blocks, which can be retrived via rpc get_block. In practice, we retrive the blocks via rpc subscribe("new_block"), which is more efficent than get_block.
To use ckb-another-exporter, you should:
- enable rpc module "Subscription"
- enable tcp_listen_address
