The `fetch_info` command returns information about objects that this server is currently fetching from the network, and how many peers have that information. It can also be used to reset current fetches.

_The `fetch_info` method is an [admin command](#connecting-to-rippled) that cannot be run by unprivileged users._

The response follows the [standard format](#response-formatting), with a successful result containing the following fields:

| `Field` | Type   | Description                                               |
|:--------|:-------|:----------------------------------------------------------|
| `info`  | Object | Map of objects being fetched and the status of that object being fetched. A ledger being fetched may be identified by its sequence number; ledgers and other objects being fetched may also be identified by their hashes. |

The fields describing a fetch in progress are subject to change without notice. The following fields may be included:

| `Field`               | Type                    | Description                |
|:----------------------|:------------------------|:---------------------------|
| `hash`                | String                  | The hash of the item being fetched. |
| `have_header`         | Boolean                 | For a ledger, whether this server has already obtained the ledger's header section. |
| `have_transactions`   | Boolean                 | For a ledger, whether this server has already obtained the transaction section of that ledger. |
| `needed_state_hashes` | Array of (Hash) Strings | The hash values of state objects still needed from this item. If more than 16 are needed, the response contains only the first 16. |
| `peers`               | Number                  | The number of peers who have this item available. |
| `timeouts`            | Number                  | The number of times that fetching this item has resulted in a timeout (2.5 seconds). |
