This dashboard monitors PostgreSQL performance and system resources by combining host-level metrics with database activity via node_cpu, node_memory_*, and pg_stat_* metrics. It highlights real-time IO, CPU, and memory usage alongside query load and contention, with panels such as Current IOwait, Current CPU, and Active sessions to quickly diagnose bottlenecks. It also tracks row-level activity like pg_stat_database_tup_fetched, pg_stat_database_tup_inserted, and pg_stat_database_tup_updated, as well as disk throughput and latency through panels like Disk IO Utilization and Disk Latency. Configurable thresholds and time range selections enable rapid drift detection and historical comparisons.
