DATA_ QUALITY_ MONITORING_ ANOMALY_ DETECTION_ STATUS view¶
This view displays a row for every time a data metric function (DMF) ran with anomaly detection enabled.
Columns¶
| Column name | Data type | Description |
|---|---|---|
scheduled_time | TIMESTAMP_LTZ | The time that the DMF is scheduled to run based on the schedule that you set for the table or view. |
change_commit_time | TIMESTAMP_LTZ | The time that the DMF trigger operation occurred, or For information about the trigger operation, see Adjust the schedule for DMFs. |
measurement_time | TIMESTAMP_LTZ | The time at which the metric was evaluated. |
table_id | NUMBER | Internal, system-generated identifier of the table that is associated with the DMF. |
table_name | VARCHAR | Name of the table that is associated with the DMF. |
table_schema | VARCHAR | Name of the schema name that contains the table that is associated with the DMF. |
table_database | VARCHAR | Name of the database that contains the table that is associated with the DMF. |
metric_id | NUMBER | Internal, system-generated identifier of the DMF. |
metric_name | VARCHAR | Name of the DMF. |
metric_schema | VARCHAR | Name of the schema that contains the DMF. |
metric_database | VARCHAR | Name of the database that contains the DMF. |
metric_return_type | VARCHAR | Return type of the DMF. |
reference_id | VARCHAR | The ID to uniquely identify the metric entity reference, known as the association ID. |
value | VARIANT | The result of the DMF evaluation. |
is_anomaly | BOOLEAN | If TRUE, the value returned by the DMF is an anomaly because it was outside the range of upperbound and lowerbound. |
upperbound | NUMBER | Highest value that should be returned by the DMF based on the anomaly-detecting algorithm. Values returned by the DMF that are above this upper bound are considered anomalies. |
lowerbound | NUMBER | Lowest value that should be returned by the DMF based on the anomaly-detecting algorithm. Values returned by the DMF that are below this lower bound are considered anomalies. |
forecast | NUMBER | Value that the anomaly-detecting algorithm predicted would be returned by the DMF. |
