As shown by the help command, a centralized sequencer is configured to serve a rollup (via `rollup_id`). The DA network to persist the sequenced batches are specified using `da_address`, `da_auth_token` and `da_namespace`.

## Metrics {#metrics}

The `centralized-sequencer` node reports Prometheus metrics when the `-metrics` flag is enabled.

By default, metrics are exported to `http://localhost:8080/metrics`.

The listening address and port can be configured with the `-metrics-address` flag.

The following metrics are available:

| **Name** | **Type** | **Tags** | **Description** |
|-------------------------------------------|-----------|-----------|------------------------------------------------------------------------|
| sequencer_gas_price | Gauge | | Gas price of the DA transaction |
| sequencer_last_blob_size | Gauge | | Last blob size submitted to the DA |
| sequencer_transaction_status | Gauge | | Transaction status of the DA transaction |
| sequencer_num_pending_blocks | Gauge | | Number of blocks pending DA submission |
| sequencer_included_block_height | Gauge | | Block height of the last DA transaction |

## Summary {#summary}

By following these steps, you will have successfully set up and connected your chain to the centralized sequencer. You can now start submitting transactions to your chain.
