# Data Exploration tab

You can export a deployment's stored training data, prediction data, and actuals to compute and monitor custom business or performance metrics on the [Custom Metrics tab](https://docs.datarobot.com/en/docs/api/reference/sdk/custom-metrics.html) or outside DataRobot. To export deployment data for custom metrics, make sure your deployment stores prediction data, generate data for a specified time range, and then view or download that data.

To access deployment data export:

1. In the top navigation bar, clickDeployments.
2. On theDeploymentstab, click on the deployment from which you want to access stored training data, prediction data, or actuals. NoteTo access the Data Exploration tab, the deployment must store prediction data. Ensure that youEnable prediction rows storage for challenger analysisin the deployment settings. The Data Exploration tab doesn't store or export Prediction Explanations, even if they are requested with the predictions.
3. In the deployment, click theData Explorationtab.

## Access or download data

To access or download prediction data, training data, or actuals:

1. Configure the following settings to specify the stored training data, prediction data, or actuals you want to export: SettingDescription1ModelSelect the deployment's model, current or previous, to export prediction data for.2Range (UTC)Select the start and end dates of the period you want to export prediction data from.3ResolutionSelect the granularity of the date slider. Select from hourly, daily, weekly, and monthly granularity based on the time range selected. If the time range is longer than 7 days, hourly granularity is not available.4ResetReset the data export settings to the default.
2. In theTraining Data,Prediction Data, andActualspanels: Availability informationCustom metric data export is off by default. Contact your DataRobot representative or administrator for information on enabling this feature.Feature flags:Enable Data Quality Table for Text Generation Target Types (Premium feature), Enable Actuals Storage for Generative Models(Premium feature) Prediction data and actuals considerationsWhen generating prediction data or actuals, consider the following:When generating prediction data, you can export up to 200,000 rows per export. If the time range you set exceeds 200,000 rows of prediction data, decrease the range.In the AI Catalog, you can have up to 100 prediction export items. If generating prediction data for export would cause the number of prediction export items in the AI Catalog to exceed that limit, delete old prediction export AI Catalog items.When generating prediction data for time series deployments, two prediction export items are added to the AI Catalog. One item is for the prediction data, and the other is for the prediction results. The Data Exploration tab links to the prediction results.When generating actuals, you can export up to 1,000,000 rows per export. If the time range you set exceeds 1,000,000 rows of actuals, decrease the time range.In the AI Catalog, you can have up to 100 actuals export items. If generating actuals data for export would cause the number of actuals export items in the AI Catalog to exceed that limit, delete old actuals export AI Catalog items.Up to 10,000,000 actuals are stored for a deployment; therefore, exporting old actuals can result in an error if no actuals are currently stored for that time period. The training data appears in theTraining Datapanel. Prediction data and actuals appear in the table below, identified byPrediction DataorActualsin theTypecolumn.
3. After the prediction data, training data, or actuals are generated:

> [!NOTE] Note
> You can also click Use data in Notebook to open a [DataRobot notebook](https://docs.datarobot.com/en/docs/classic-ui/dr-notebooks/index.html) with cells for exporting training data, prediction data, and actuals.

## Use exported deployment data for custom metrics

To use the exported deployment data to create your own custom metrics, you can implement a script to read from the CSV file containing the exported data and then calculate metrics using the resulting values, including [columns automatically generated during the export process](https://docs.datarobot.com/en/docs/classic-ui/mlops/monitor/data-exploration.html#datarobot-column-reference).

This example uses the exported prediction data to calculate and plot the change in the `time_in_hospital` feature over a 30-day period using the DataRobot prediction timestamp ( `DR_RESERVED_PREDICTION_TIMESTAMP`) as the DateFrame index (or row labels). It also uses the exported training data as the plot's baseline:

```
import pandas as pd
feature_name = "<numeric_feature_name>"
training_df = pd.read_csv("<path_to_training_data_csv>")
baseline = training_df[feature_name].mean()
prediction_df = pd.read_csv("<path_to_prediction_data_csv>")
prediction_df["DR_RESERVED_PREDICTION_TIMESTAMP"] = pd.to_datetime(
    prediction_df["DR_RESERVED_PREDICTION_TIMESTAMP"]
)
predictions = prediction_df.set_index("DR_RESERVED_PREDICTION_TIMESTAMP")["time_in_hospital"]
ax = predictions.rolling('30D').mean().plot()
ax.axhline(y=baseline - 2, color="C1", label="training data baseline")
ax.legend()
ax.figure.savefig("feature_over_time.png")
```

### DataRobot column reference

DataRobot automatically adds the following columns to the prediction data generated for export:

| Column | Description |
| --- | --- |
| DR_RESERVED_PREDICTION_TIMESTAMP | Contains the prediction timestamp. |
| DR_RESERVED_PREDICTION | Identifies regression prediction values. |
| DR_RESERVED_PREDICTION_<Label> | Identifies classification prediction values. |

---
