Supported WarehousePG versions
WarehousePG Enterprise Manager (WEM) is compatible with the following versions of WarehousePG (WHPG):
| WHPG version | Supported RHEL versions |
|---|---|
| 6.x | RHEL 7, RHEL 8, RHEL 9 |
| 7.x | RHEL 8, RHEL 9 |
Supported platforms
| Component | Supported RHEL versions |
|---|---|
| WEM | RHEL 8, RHEL 9 |
| ClickHouse | RHEL 8, RHEL 9 |
WEM requires ClickHouse for metrics and log storage. You can deploy ClickHouse inside your WHPG cluster, on the coordinator or standby coordinator, or on a separate host outside the cluster.
Host agent compatibility
WEM 1.4 requires acp-host-agent 1.1.0 or later on every cluster node, an older host agent can't connect. See Upgrading the host agent if you're upgrading WEM.
Note
Neither WEM nor ClickHouse supports RHEL 7. If you're running WHPG 6.x on RHEL 7, you can't deploy WEM or ClickHouse on a node inside that cluster. Deploy WEM and ClickHouse on a separate host running a supported RHEL version instead. WEM can still monitor the RHEL 7 cluster remotely.
