Metrics support v1.3.2

The December 2025 Innovation Release of EDB Postgres AI is available. For more information, see the release notes.

Hybrid Manager (HM) collects and displays a wide range of metrics to give you comprehensive visibility into your database clusters.

The availability of metrics you can see in the HM console depends on the metric and cluster type.

Summarized overview

This overview shows the available metrics per database cluster type.

	Host metrics	Postgres metrics	Cluster metrics	Query metrics	Recommendations	Logs
HM-managed cluster	Yes	Yes	Yes	Yes	Yes	Yes
External: Self-managed cluster	Yes	Yes	No	Yes	Yes	Yes
External: CNPG database cluster	Yes	Yes	Yes	Yes	Yes	Yes
External: AWS RDS database	Yes	partial support	No	No	No	No

Limitations

Currently, the Hybrid Manager supports monitoring for EDB CloudNativePG clusters. Monitoring for open-source CloudNativePG clusters will be supported in a future release.
Monitoring isn't supported for external EDB Postgres Distributed clusters.

Detailed overview

Host metrics

Host metrics display resource utilization for the underlying server infrastructure hosting your database instances. You can see them in the Estate view and in the cluster view's Monitoring tab in the Host section.

Metric	HM-managed cluster	External: Self-managed cluster	External: CNPG database cluster	External: AWS RDS database
Memory	Yes	Yes	Yes	Yes
CPU	Yes	Yes	Yes	Yes
Storage	Yes	Yes	Yes	Yes
Disk IOPS	Yes	Yes	Yes	Yes
Disk throughput	Yes	Yes	Yes	Yes
Network activity	Yes	Yes	Yes	Yes

Important

Memory, CPU, and storage metrics show the average percentage usage for Postgres processes on the hosting node. To monitor system-wide usage on HM-managed clusters, use Grafana. System-wide monitoring isn't currently supported for external clusters.

Postgres metrics

Postgres metrics show performance and operational statistics specific to the Postgres database server. You can see them in the Estate view and in the cluster view's Monitoring tab.

Cluster metrics

Cluster metrics are host and postgres metrics, individual and aggregated for database deployments spanning multiple nodes (HA, AHA, and DHA topologies). You can see them in the Estate view and in the cluster view's Monitoring tab in the Topology and Replication sections. Cluster metrics aren't displayed for single node deployments.

Metric	HM-managed cluster	External: Self-managed cluster	External: CNPG database cluster	External: AWS RDS database
RAFT status (AHA, and DHA)	Yes	No	No	No
Replication slot status	Yes	No	Yes	No
Clock skew	Yes	No	Yes	No
Node status	Yes	No	Yes	No
Transaction rate	Yes	No	Yes	No
Connections (total)	Yes	No	Yes	No
Connections (per node)	Yes	No	Yes	No
Memory (per node)	Yes	No	Yes	No
Storage (per node)	Yes	No	Yes	No
WAL size (per node)	Yes	No	Yes	No
Replication status	Yes	No	Yes	No

Query metrics

Query metrics offer insights into the performance and characteristics of the database Postgres queries being executed. You can see them in the cluster view's Query diagnostics tab.

Metric	HM-managed cluster	External: Self-managed cluster	External: CNPG database cluster	External: AWS RDS database
Query latency	Yes	Yes	Yes	No
Nr. of queries executed	Yes	Yes	Yes	No
Query latency histogram	Yes	Yes	Yes	No
Nr. of active sessions	Yes	Yes	Yes	No

Recommendations

Recommendations suggest actions and optimizations based on observed metrics to improve your database environment (for example, improve indexes). You can see them in the cluster view's Recommendations tab.

Metric	HM-managed cluster	External: Self-managed cluster	External: CNPG database cluster	External: AWS RDS database
Indexes	Yes	Yes	Yes	No
Statistics	Yes	Yes	Yes	No
Configuration	Yes	Yes	Yes	No
Security	No	No	No	No
Workload	No	No	No	No

Logs

Logs present raw and processed log data from various components of your database system for troubleshooting and auditing. You can see them in the cluster view's Logs tab.

Metric	HM-managed cluster	External: Self-managed cluster	External: CNPG database cluster	External: AWS RDS database
Logs	Yes	Yes	Yes	No
