SQL Server Monitoring – Table Size

Updated August 29, 2021.


To get a baseline of the size of the tables in the databases.


This feature queries the DMV sys.dm_db_partition_stats which returns page and row-count information for the objects queried.


The report page Database Size has 2 line charts, one showing the number of rows in the tables, and the other showing the data size, the index size, the reserved space and the unused space in KB.

The x-axis for the charts is at the day level.

The report has 3 buttons to select the level where the tooltips are showing data. For this feature Database, Schema and Object can be selected.

When hovering over the charts tooltips are showing detailed insight by showing the top 5 databases, schemas, or objects (depending on the tooltip button selections) with regards of number of rows, and size in terms of data, index and used space.
