The Crunchy Postgres for Kubernetes Monitoring stack is a fully integrated solution for monitoring and visualizing metrics captured from PostgreSQL clusters created using PGO. By leveraging pgMonitor to configure and integrate the various tools, components and metrics needed to effectively monitor PostgreSQL clusters, PGO Monitoring provides an powerful and easy-to-use solution to effectively monitor and visualize pertinent PostgreSQL database and container metrics. Included in the monitoring infrastructure are the following components:

  • pgMonitor - Provides the configuration needed to enable the effective capture and visualization of PostgreSQL database metrics using the various tools comprising the PostgreSQL Operator Monitoring infrastructure
  • Grafana - Enables visual dashboard capabilities for monitoring PostgreSQL clusters, specifically using Crunchy PostgreSQL Exporter data stored within Prometheus
  • Prometheus - A multi-dimensional data model with time series data, which is used in collaboration with the Crunchy PostgreSQL Exporter to provide and store metrics
  • Alertmanager - Handles alerts sent by Prometheus by deduplicating, grouping, and routing them to receiver integrations.

By leveraging the installation method described in this section, Crunchy Postgres for Kubernetes Monitoring can be deployed alongside Crunchy Postgres for Kubernetes.
