Dasha is an open-source dashboard that monitors PostgreSQL clusters using a read-only role without installing agents or extensions on database hosts. It aggregates per-instance statistics across all nodes, including replicas, to provide a unified view of the fleet's health. The tool calculates a composite Health Score and offers prioritized recommendations based on combined data from primary and standby instances.
- Zero footprint: No agents or new extensions required on database hosts.
- Unified view: Aggregates per-instance stats across all cluster nodes and replicas.
- Context-aware: Detects issues like unused indexes that are active on standbys.
- Centralized: One Dasha instance can serve multiple clusters and their replicas.
- Actionable: Provides a 0-100 Health Score with drill-down recommendations.
