# Catalog: Add/Modify Monitor

You can add and modify monitors directly from the Data Catalog's Asset Details view, without leaving the context of the asset you're working on.

## Monitor Management Options

### Option 1: Dedicated Config Module (Recommended for Bulk Setup)

* **Best for**: Setting up multiple monitors across different assets
* **Access**: Main navigation Config section
* **Guide**: [Enable Asset Monitoring](/data-quality/enable-asset-monitoring.md)

### Option 2: Catalog Integration (This Guide)

* **Best for**: Asset-specific monitoring while browsing catalog
* **Access**: Individual asset details pages
* **Context**: Full asset metadata and lineage available
