In this presentation, we will explore strategies for maintaining observability of Postgres databases in complex cloud environments. Topics include leveraging eBPF for generating comprehensive service maps and instrumenting Postgres calls across various client applications to specific databases. Additionally, we explore automatic discovery mechanisms for topologies within High Availability (HA) Postgres clusters, facilitated by different Kubernetes Operators. Furthermore, the talk addresses the importance of monitoring underlying cloud resources, encompassing virtual machines (VMs), storage volumes, and network components.
