# Block Bot Monitoring

### What is Block Bot Monitoring?

Block Bot Monitoring is used to track the gas consumption of blocks in the target chain, thereby allowing for the prediction of possible situations on the chain.

### Typical Scenarios for Block Bot Monitoring

1. Monitoring the value of block Gas Fees
2. Monitoring the proportion of block gas consumption relative to the maximum block limit
3. Monitoring the block miner

**Supported Data Sources**

| Data Source | Type     | Stability |
| ----------- | -------- | --------- |
| Ethereum    | on chain | Very High |

### How to Configure Block Bot Monitoring?

After logging into the ChainBot platform, click "Create Bot" -> "Block Monitor" in the top right corner.
