What we monitor<br>Five checks that catch 90% of data quality issues.

Freshness Monitoring<br>Know the instant a table stops updating. Track staleness down to the minute across every dataset.

Row Count Spikes<br>Catch volume anomalies — sudden spikes or drops vs. your rolling average.<br>+47%

Null Rate<br>Monitor null rates per column. Alert when they drift past your threshold.<br>0.02%

Duplicate Detection<br>Find duplicate rows on key columns before they corrupt downstream aggregations.

Schema Drift<br>Detect column additions, removals, and type changes the moment they hit your DB.<br>- feeDECIMAL(10,2)

How it works<br>Three steps. Five minutes. Done.

Step 01Connect<br>Add your Postgres connection string. Read-only access, encrypted at rest.

Step 02Configure<br>Pick tables, choose check types, set thresholds. Schedule or run on-demand.

Step 03Relax<br>Get alerted on failures with context. Review the daily health report over coffee.

Not another data platform.<br>Pegel does one thing: monitor the quality of data already in your Postgres database. No warehouse migration. No dbt integration. No 200-page setup guide. Connect a read-only user, pick your tables, set thresholds, and get alerts when something breaks. If you have a Postgres database and a Slack channel, you can be running in five minutes.
