                        Refresh rate of the table (default: 1)

Usage

• The script will connect to cosmos websocket, process newly produced blocks, consensus events and save them to result/[height]/ws_votes.json

WS_EVENTS = [
    {"jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='Vote'"], "id": 1}, # Prevote + Precommit for each round in the block 
    {"jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='NewRoundStep'"], "id": 2},
    {"jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='ValidatorSetUpdates'"], "id": 3},
    {"jsonrpc": "2.0", "method": "subscribe", "params": ["tm.event='NewBlock'"], "id": 4}
]

• The script will start fetching consensus state from /consensus_state endpoint non-stop, process and save data to result/[height]/fetch_votes.json

python3 main.py --rpc https://story-testnet-cosmos-rpc.crouton.digital --ws wss://story-testnet-cosmos-ws.crouton.digital/websocket --log_lvl debug --save_all

If you don't need to save all blocks data and save only specific height metrics:

• remove --save_all flag
• specify --target_height. The script won't save any metrics from other blocks except this one.
• specify --post_target_check_blocks_num (default: 10) if target_height is provided. The script will save signatures, consensus rounds, validators prevotes and precommits for 10 post target blocks
