Configure usage and diagnostic data collection for SQL Server on Linux

Applies to: SQL Server - Linux

By default, Microsoft collects information about how its customers use SQL Server. Specifically, SQL Server collects information about the installation experience, usage, and performance. This information helps Microsoft improve the product to better meet customer needs. For example, Microsoft collects information about what kinds of error codes customers encounter so that we can fix related bugs, improve our documentation about how to use SQL Server, and determine whether features should be added to the product to better serve customers.

This document provides details about what kind of information is collected, and about how to configure SQL Server on Linux to send that collected information to Microsoft. SQL Server includes a privacy statement that explains what information we do and don't collect from users. For more information, see the privacy statement.

Specifically, Microsoft doesn't send any of the following types of information through this mechanism:

• Any values from inside user tables
• Any sign-in credentials or other authentication information
• Personal data

SQL Server always collects and sends information about the installation experience from the setup process so that we can quickly find and fix any installation problems that the customer is experiencing. SQL Server can be configured not to send information (on a per-server instance basis) to Microsoft through mssql-conf. mssql-conf is a configuration script that installs with SQL Server for Red Hat Enterprise Linux, SUSE Linux Enterprise Server, and Ubuntu.

Note

You can disable the sending of information to Microsoft only in paid versions of SQL Server.

Disable usage and diagnostic data collection

This option lets you change if SQL Server sends usage and diagnostic data collection to Microsoft or not. By default, this value is set to true. To change the value, run the following commands:

Important

You can not turn off usage and diagnostic data collection for free editions of SQL Server, Express and Developer.

On Red Hat, SUSE, and Ubuntu

1. Run the mssql-conf script as root with the set command for telemetry.customerfeedback. The following example turns off usage and diagnostic data collection by specifying false.

   sudo /opt/mssql/bin/mssql-conf set telemetry.customerfeedback false
   

2. Restart the SQL Server service:

   sudo systemctl restart mssql-server
   

In a Linux container

To disable usage and diagnostic data collection in a Linux container, you must have the container persist your data.

1. Add an mssql.conf file with the lines [telemetry] and customerfeedback = false in the host directory:

   echo '[telemetry]' >> <host directory>/mssql.conf
   

   echo 'customerfeedback = false' >> <host directory>/mssql.conf
   

2. Run the container image:

   Important

   The SA_PASSWORD environment variable is deprecated. Use MSSQL_SA_PASSWORD instead.

   docker run -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=<password>' -p 1433:1433 -v <host directory>:/var/opt/mssql -d mcr.microsoft.com/mssql/server:2022-latest
   

   docker run -e "ACCEPT_EULA=Y" -e "MSSQL_SA_PASSWORD=<password>" -p 1433:1433 -v <host directory>:/var/opt/mssql -d mcr.microsoft.com/mssql/server:2022-latest
   

Caution

Your password should follow the SQL Server default password policy. By default, the password must be at least eight characters long and contain characters from three of the following four sets: uppercase letters, lowercase letters, base-10 digits, and symbols. Passwords can be up to 128 characters long. Use passwords that are as long and complex as possible.

Local Audit for SQL Server on Linux usage and diagnostic data collection

SQL Server contains Internet-enabled features that can collect and send information about your computer or device ("standard computer information") to Microsoft. The Local Audit component of SQL Server usage and diagnostic data collection can write data collected by the service to a designated folder, representing the data (logs) that is sent to Microsoft. The purpose of the Local Audit is to allow customers to see all data Microsoft collects with this feature, for compliance, regulatory or privacy validation reasons.

In SQL Server on Linux, Local Audit is configurable at instance level for SQL Server Database Engine. Other SQL Server components and SQL Server Tools don't have Local Audit capability for usage and diagnostic data collection.

Enable Local Audit

This option enables Local Audit and lets you set the directory where the Local Audit logs are created.

1. Create a target directory for new Local Audit logs. The following example creates a new /tmp/audit directory:

   sudo mkdir /tmp/audit
   

2. Change the owner and group of the directory to the mssql user:

   sudo chown mssql /tmp/audit
   sudo chgrp mssql /tmp/audit
   

3. Run the mssql-conf script as root with the set command for telemetry.userrequestedlocalauditdirectory:

   sudo /opt/mssql/bin/mssql-conf set telemetry.userrequestedlocalauditdirectory /tmp/audit
   

4. Restart the SQL Server service:

   sudo systemctl restart mssql-server
   

In a Linux container

To enable Local Audit in a Linux container, you must have the container persist your data.

1. The target directory for new Local Audit logs will be in the container. Create a target directory for new Local Audit logs in the host directory on your machine. The following example creates a new /audit directory:

   sudo mkdir <host directory>/audit
   

2. Add an mssql.conf file with the lines [telemetry] and userrequestedlocalauditdirectory = <host directory>/audit in the host directory:

   echo '[telemetry]' >> <host directory>/mssql.conf
   

   echo 'userrequestedlocalauditdirectory = <host directory>/audit' >> <host directory>/mssql.conf
   

3. Run the container image

   docker run -e 'ACCEPT_EULA=Y' -e 'MSSQL_SA_PASSWORD=<password>' -p 1433:1433 -v <host directory>:/var/opt/mssql -d mcr.microsoft.com/mssql/server:2022-latest
   

   docker run -e "ACCEPT_EULA=Y" -e "MSSQL_SA_PASSWORD=<password>" -p 1433:1433 -v <host directory>:/var/opt/mssql -d mcr.microsoft.com/mssql/server:2022-latest
   

Caution

Your password should follow the SQL Server default password policy. By default, the password must be at least eight characters long and contain characters from three of the following four sets: uppercase letters, lowercase letters, base-10 digits, and symbols. Passwords can be up to 128 characters long. Use passwords that are as long and complex as possible.
