These are the currently known issues and limitations identified in the WarehousePG Enterprise Manager (WEM) release. Where applicable, we've included workarounds to help you mitigate the impact of these issues. These issues are actively tracked and are planned for resolution in a future release.
Deployment & infrastructure
- Each WEM deployment is designed to manage and monitor only one WarehousePG (WHPG) cluster. Managing multiple clusters requires separate, dedicated WEM installations for each.
- WEM can't be installed on Red Hat Enterprise Linux 7. This restriction applies only to the host running the WEM application. WEM is fully capable of monitoring WHPG clusters running on RHEL 7 nodes.
Query monitoring
- The Query Editor supports running EXPLAIN on queries you write, but WEM doesn't capture execution plans for queries that are already running. To investigate the plan of an in-flight query, connect to the cluster directly using
psqland runEXPLAINagainst the query text.
Alerting
- WEM doesn't support sending alert notifications directly via email. To receive email notifications, configure an email receiver in Alertmanager and point WEM to your Alertmanager endpoint using
ALERTMANAGER_URL. See Alertmanager notification configuration for details.
Access management
- The pg_hba.conf tab displays a security notice warning about trust-based authentication rules. Some of these rules are created automatically by
gpinitsystemduring cluster initialization. Modifying them can break internal WHPG communication and make the cluster unavailable. Review any proposed changes carefully before applying them.
