# Profiler Configuration
> Set the default profiler metrics computed per data type, and control whether sample data is stored and readable platform-wide.
# Profiler Configuration
Profiler Configuration sets the platform-wide defaults the profiler applies before any individual profiler workflow runs:
* Which metrics it computes for each column data type
* Whether it stores or reads sample data
Setting sensible defaults here means new profiler workflows across every team start from a consistent, already-tuned baseline instead of each owner reconfiguring the same metrics from scratch. These defaults apply to every profiler workflow unless a workflow overrides them. For more information about running the profiler itself, see [Profiler Workflow](/v2.0.x/how-to-guides/data-quality-observability/profiler/profiler-workflow).
## How to Access
Navigate to **Settings** > **Preferences** > **Profiler Configuration**.
## Metric Configuration
By default, the profiler computes every available metric for every column. Metric Configuration lets you turn specific metrics off per data type, which is useful when:
* A metric doesn't make sense for that type, such as computing a mean on a string column
* You want to keep profiling fast on very wide tables by skipping metrics your team doesn't act on
Add a row per data type to control which metrics the profiler computes for columns of that type:
1. Click **Add Field**.
2. Choose a **Data Type**, for example `INT`, `STRING`, or `TIMESTAMP`. Each data type can only be configured once.
3. Choose which **Metric Type(s)** to disable for that data type, or leave it on **All** to disable every metric for that type.
4. Use the **Disable** toggle to turn the whole row off without deleting it.
Click the **X** button next to a row to remove it.
## Sample Data Ingestion Configuration
Sample data lets users preview real rows from a table directly in OpenMetadata, which is convenient for spotting data quality issues at a glance, but it also means row-level data is brought outside the source system:
| Setting | Description | Default |
| :-------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | :------ |
| **Enable Storing of Sample Data** | Allows OpenMetadata to store the sample data. This setting overrides the source configuration | On |
| **Enable Reading of Sample Data** | Allows OpenMetadata to read the sample data. This doesn't save the sample data, but it is temporarily brought into the ingestion agent's infrastructure for processing. If reading is off but storing is on, reading turns on automatically | On |
