# slow_queries

The `slow_queries` table contains the slow queries of GreptimeDB:

:::tip NOTE
The `slow_queries` table requires slow query logging to be enabled. See [Slow Query](/user-guide/deployments-administration/monitoring/slow-query.md) for configuration details.

```sql
USE greptime_private;

SELECT * FROM slow_queries;
```

The output is as follows:
