# Stats API
|
|
|
|
Use the stats operation to monitor shard indexing backpressure.
|
|
|
|
## Stats
|
|
Introduced 1.2
|
|
{: .label .label-purple }
|
|
|
|
Returns node-level and shard-level stats for indexing request rejections.
|
|
|
|
#### Request
|
|
|
|
```json
|
|
GET _nodes/_local/stats/shard_indexing_pressure
|
|
```
|
|
|
|
If `enforced` is `true`:
