:::note

- The Home tab provides critical infrastructure visibility through real-time node status, alert trends, and deployment topology.
- The **Parents/Children/Standalone** breakdown shows your streaming architecture at a glance, helping you understand your data collection hierarchy.
- The **Data replication** metrics indicate how many nodes have no replication, single replication, or multi-replication for high availability.
- Use the **Nodes with the most alerts** chart to quickly identify problematic hosts requiring immediate attention, and the **Top alerts** table to spot recurring issues that may need alert tuning or infrastructure remediation.
