Support scope

The PG AI Hybrid Manager 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 PG AI Console depends on the metric and cluster type. This page provides an overview of the support scope and tells you where to find each grouping of metrics in the PG AI Console.

Summarized overview

Here is an overview of the available metrics per database cluster type.

  • Self-managed multi-node instances are not displayed as groups at the moment. Each data node instance and its metrics are displayed separately. Clustered views for multi-node instances will be added in a coming release.

  • Currently, the Hybrid Manager supports monitoring for EDB CloudNativePG clusters. Monitoring for open-source CloudNativePG clusters will be supported in a coming release.

Detailed overview

Host metrics

Host metrics display resource utilization for the underlying server infrastructure hosting your database instances. They are visible through the Estate view, and also through the cluster view ► Monitoring tab ► Host section.

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 itself. They are visible through the Estate view, and also through the cluster view ► 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). They are visible through the Estate view, and also through the cluster view ► Monitoring tab ► Topology and Replication sections. Cluster metrics are not displayed for single node deployments.

Query metrics

Query metrics offer insights into the performance and characteristics of the database Postgres queries being executed. They are visible through the cluster view ► Query diagnostics tab.

Recommendations

Recommendations suggest actions and optimizations based on observed metrics to improve your database environment (e.g. improve indexes). They are visible through the cluster view ► Recommendations tab.
