# Performance diagnostic

When a performance issue occurs while using Remote Desktop Manager Windows, the support team may ask you to send a few details regarding your workspace, system settings, etc. Follow one of the two methods below to gather the information and send it the support team.

### Send performance trace via Remote Desktop Manager

1. Open ***File*** – ***My workspace information***.
2. Click on the ***Email report to support*** button to send the information to the support team.
3. Open ***Help*** – ***System diagnostic***.
4. Click on the ***Send*** button.
5. Include enough information to link the report to the appropriate ticket. Remember to enter your username if the process was started from the forum.
6. Next, go to ***Help*** – ***Performance profiling.***
7. In Remote Desktop Manager, hold the <kbd>Ctrl</kbd> key and press the refresh button.
8. Information will be added in the ***Performance*** tab of the performance profiling window opened during step #6.
9. Click on the ***Send trace to support*** button. Again, ensure that you include enough information to link the report to the appropriate ticket, and enter your forum username if the process was started from the forum.

### Email a Disk usage by Top Tables report via SSMS

For Devolutions Server, SQL, and SQL Azure workspaces, a ***Disk usage by Top Tables*** ***report*** from ***SQL Server Management Studio (SSMS)*** can be generated in order to assess the number of records in specific database tables. Here's how to do so:

1. Open ***SQL Server Management Studio (SSMS)***.
2. Right-click the database and select ***Reports*** – ***Standard Reports*** – ***Disk Usage by Top Tables***.
3. Send the report to <service@devolutions.net>.

Here is an example of what the report looks like.

Here is the ***SQL query*** to get the same result if the database is hosted on Azure.

        a3.name AS SchemaName,
        a2.name AS TableName,

                SUM (CASE   WHEN (ps.index_id < 2) THEN (ps.in_row_data_page_count + ps.lob_used_page_count + ps.row_overflow_used_page_count)
                            ELSE (ps.lob_used_page_count + ps.row_overflow_used_page_count) END
                    ) AS data,
                SUM (ps.used_page_count) AS used
                FROM sys.dm_db_partition_stats ps
                GROUP BY ps.object_id
            ) AS a1

    INNER JOIN sys.schemas a3 ON (a2.schema_id = a3.schema_id)
