# Monitoring | Farmguardians

The **Farmguardian** section provides a list of all available health checks in the load balancer, including descriptions and their application to various farms.

**Farmguardian** offers advanced backend monitoring, automatically disabling any server that fails a health check and marking its IP as blacklisted.

Health checks can be either **pre-configured** or **custom**. You can identify the type by looking at the action column: **pre-configured** checks have grayed-out settings, while custom checks can be edited by clicking the pencil icon.
