# Top Queries

Datasentinel collects incremental execution statistics for all queries every minute.

This makes it easy to identify the top-performing queries over a specific period and on specific metrics, such as those generating the most Disk Access, Temporary Disk I/O or taking the most Execution Time.

The dashboard comprises three parts:

* The upper graph provides a visual representation of the queries impact over time.
* The small intermediate graphs help correlate these statistics with [Cluster or System Metrics](https://docs.datasentinel.io/manual/features/key-features/cluster-and-system-metrics).\
  Refer to[ Metric  Correlation](https://docs.datasentinel.io/manual/features/tips-and-hints/metric-correlation) for more details.
* The lower part provides details on a query-by-query basis for all the execution statistics

This feature allows for in-depth analysis of top queries across various dimensions, including:

> * total time
> * calls
> * rows
> * shared blocks hit
> * shared blocks read
> * shared blocks dirtied
> * shared blocks written
> * temporary blocks read
> * temporary blocks written
> * read time
> * write time
> * local blocks hit
> * local blocks read
> * local blocks dirtied
> * local blocks written
> * WAL size (since Postgres 13).

It also displays the run-time statistics globally, by call, or by second.
