Problem overview
PostgreSQL is a robust database solution used in critical applications. A stopped PostgreSQL service can disrupt application functionality, lead to data unavailability, or result in service-level agreement (SLA) breaches. This policy ensures that PostgreSQL services stay operational with minimal manual intervention by automatically restarting services and notifying your team.
Monitors
critical 3 checks
- DB Storage Alert (Disk Free monitor) DB Storage Alert (Disk Free monitor)
- Postgres Service (Service monitor) DB Storage Alert (Disk Free monitor)
- RepMgr Service (Service monitor) DB Storage Alert (Disk Free monitor)

This policy continuously monitors the status of PostgreSQL services on devices tagged with “PSQL.” If the service stops or fails, the monitor triggers an automatic restart and generates a real-time alert to notify the operations team. This helps ensure seamless database operations and minimizes downtime for applications dependent on PostgreSQL.
Use cases
- Maintaining database availability for mission-critical applications.
- Proactively monitoring PostgreSQL instances in production, staging, or testing environments.
- Avoiding downtime for data-driven services, such as web applications or analytics platforms.
- Supporting PostgreSQL clusters in distributed database setups.
Recommendations
- Tagging: Ensure all PostgreSQL servers are tagged with “PSQL” for accurate monitoring. We recommend automatically tagging to avoid missing key devices. See “Service Based Tagging” automation as an example.
- Testing: Simulate service stoppages to validate automatic restarts and real-time alerts.
- Regular Maintenance: Keep PostgreSQL servers updated and perform routine database maintenance (e.g., vacuuming, indexing).
- Alert Configuration: Set alerting to ensure timely notifications reach the right team members.
- Resource Monitoring: Pair this policy with monitors for CPU, memory, and storage usage to identify resource constraints that might lead to service interruptions.
