This check lets you track the performance of your SQL Server instances. It collects metrics for number of user connections, rate of SQL compilations, and more.
You can also create your own metrics by having the check run custom queries.
Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the Autodiscovery Integration Templates for guidance on applying these instructions.
The SQL Server check is included in the Datadog Agent package, so you don’t need to install anything else on your SQL Server instances.
Make sure that your SQL Server instance supports SQL Server authentication by enabling “SQL Server and Windows Authentication mode” in the server properties. Server Properties -> Security -> SQL Server and Windows Authentication mode
Create a read-only login to connect to your server:
CREATE LOGIN datadog WITH PASSWORD = '<PASSWORD>'; CREATE USER datadog FOR LOGIN datadog; GRANT SELECT on sys.dm_os_performance_counters to datadog; GRANT VIEW SERVER STATE to datadog;
init_config: instances: - host: "<SQL_HOST>,<SQL_PORT>" username: datadog password: "<YOUR_PASSWORD>" connector: odbc # alternative is 'adodbapi' driver: SQL Server
See the example check configuration for a comprehensive description of all options, including how to use custom queries to create your own metrics.
Note: The (default) provider
SQLOLEDB is being deprecated. To use the newer
MSOLEDBSQL provider, set the
adoprovider variable to
MSOLEDBSQL in your
sqlserver.d/conf.yaml file after having downloaded the new provider from Microsoft. It is also possible to use the Windows Authentication and not specify the username/password with:
Restart the Agent to start sending SQL Server metrics to Datadog.
Extra configuration steps are required to get the SQL Server integration running on a Linux host:
odbcinst.inifiles into the
conf.yamlfile to use the
odbcconnector and specify the proper driver as specified in the
Run the Agent’s
status subcommand and look for
sqlserver under the Checks section.

Returns CRITICAL if the Agent cannot connect to SQL Server to collect metrics, otherwise OK.

See the main documentation for more details about how to test and develop Agent based integrations.
To run the tests on Windows, an instance of MSSQL is expected to run on the host. The name of the database instance and the credentials reflect what we have on the CI environment, so that might not work out of the box on a local development environment.
On Linux, a Docker container running a MSSQL instance is automatically started before running the tests. We use unixODBC and FreeTDS to talk to the database so, depending on the Linux distribution, you need to install additional dependencies on your local dev environment before running the tests. For example these are the installation steps for Ubuntu 14.04:
sudo apt-get install unixodbc unixodbc-dev tdsodbc
brew install unixodbc brew install freetds --with-unixodbc
