Database monitoring
PostgreSQL monitoring that runs a real query
A open port doesn't mean Postgres can serve a query: a primary can accept connections with a full disk, a replica can answer while minutes behind. NoDisrupt connects the way your app does, runs a validation query, and alerts on the result.
Monitor PostgreSQL freeWhat real PostgreSQL monitoring watches
"Is the port open" is the least informative signal a database can give you. NoDisrupt watches the things that actually predict an outage:
Connectivity & authentication
Connect with real credentials over SSL: proving auth and the network path, not just an open socket.
Validation query latency
Run a live SELECT on a schedule and alert on how long it takes: the number that actually predicts user pain.
Value assertions
Assert on what a query returns (row counts, queue depth, pending payments) to catch silent failures that never throw an error.
Staged timing breakdown
Split each check into TCP, TLS, auth and query execution so an alert tells you where the time went, not just that it's slow.
NoDisrupt monitors Postgres, MySQL and Redis the same way: connect, query, assert, alert.
PostgreSQL monitoring FAQ
How do I monitor PostgreSQL uptime?
NoDisrupt connects to your Postgres instance with real credentials and runs a validation query on a schedule. If the query returns, connectivity, authentication and the query engine are all proven: a far stronger signal than a port check.
Can NoDisrupt alert on slow Postgres queries?
Yes. Every check records query latency, and you can alert when it crosses a threshold, catching gradual degradation from a growing table or stale index before it becomes a timeout.
Does it need an agent installed on the database?
No. NoDisrupt monitors PostgreSQL over a standard connection, the same way your application connects: no agent or extension to install.
Can I assert on query results, not just uptime?
Yes. Run a scheduled query and assert on the value it returns (failed-order counts, undrained queues, pending records) to catch silent failures where nothing is technically 'down'.
Catch PostgreSQL problems before your users do
Connect, run a real query, and get alerted on latency and results: in under a minute, no agent.
