| ---------------- | --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| No Data          | No Data         | The default option for **No Data** events.<br/>Sets alert instance state to `Pending`, then `No Data` after the pending period. <br/> The alert rule immediately creates a new `DatasourceNoData` alert instance after evaluation, with the alert rule's name, UID, and the data source UID as labels. |
| Error            | Error           | The default option for **Error** events.<br/>Sets alert instance state to `Pending`, then 'Error`after the pending period. <br/> The alert rule immediately creates a new`DatasourceError` alert instance after evaluation, with the alert rule's name, UID, and the data source UID as labels.        |
| No Data or Error | Alerting        | Sets the alert instance state to `Pending` and then transitions to `Alerting` once the pending period ends. If you sent the pending period to 0, the alert instance state is immediately set to `Alerting`.                                                                                            |
| No Data or Error | Normal          | Sets alert instance state to `Normal`.                                                                                                                                                                                                                                                                 |
| No Data or Error | Keep Last State | Maintains the alert instance in its last state. Useful for mitigating temporary issues.                                                                                                                                                                                                                |
