Connect your database by creating a dedicated monitoring user, enabling its query-statistics source, and running the QueryComment collector.
QueryComment reads aggregate query, engine, and infrastructure telemetry. The collector does not proxy application traffic and does not write to your application tables.

​
Before you start

Make sure you have:
  • A QueryComment ingest token from your dashboard.
  • Permission to create a monitoring user and grant monitoring privileges.
  • Outbound HTTPS access from the collector host to ingest.querycomment.com.

​
Select your database

PostgreSQL

Enable pg_stat_statements, then configure the QueryComment PostgreSQL receiver.

MySQL

Enable statement digests in performance_schema.

SQL Server

Create a read-only monitoring login for plan-cache query statistics.
Each guide includes the required database permissions and checks that confirm QueryComment can collect the necessary data.
