Note
This guide assumes you have installed Prometheus and Loki.

- WHPG version 7.x running on RHEL 8 or RHEL 9.
- A separate host for WarehousePG Enterprise Manager (WEM), running RHEL 8 or RHEL 9.
- Loki 3.5 or later.
- Prometheus 3.5.0 or later.
- A database user that holds the superuser role and is able to connect to your WHPG cluster from the WEM host.
- Optional: An active Anthropic account and a valid API key are required to enable the AI Assistant for query writing and optimization.
