# Modify Schema Drift Monitors

Schema Drift Monitors are automatically activated for all tables upon connecting a data source. They identify alterations in the schema, such as the addition, deletion, or modification of tables or columns, and data type changes. Such adjustments can potentially lead to compatibility challenges with the corresponding database and the applications leveraging these tables.

{% hint style="info" %}
Schema Drift monitors do not need to be created, however the settings can be modified.
{% endhint %}

* Under **All Monitors tab** , click on the **Schema Drift** pill to view the list of Schema Drift monitors.
* Click on the **ellipsis menu (⋮)** to view the monitor. The **Modify Monitor** modal will pop up and gives you option to modify, disable and delete monitor.
