![]() Grafana lists these variables in dropdown select boxes at the top of the dashboard to help you change the data displayed in your dashboard. Instead of hard-coding details such as server, application, and sensor names in metric queries, you can use variables. You can create queries with the Microsoft SQL Server data source’s query editor when editing a panel that uses a MS SQL data source.įor details, refer to the query editor documentation. You can define and configure the data source in YAML files as part of Grafana’s provisioning system.įor more information about provisioning, and for available configuration options, refer to Provisioning Grafana. We recommend that you use the latest available service pack for optimal compatibility. If you use older versions of Microsoft SQL Server, such as 20R2, you might need to disable encryption before you can connect the data source. GRANT SELECT ON dbo.YourTable3 TO grafanareaderĪlso, ensure that the user doesn’t have any unwanted privileges from the public role. Grant only SELECT permissions on the specified database and tables that you want to query to the database user you specified when you added the data source: CREATE USER grafanareader WITH PASSWORD 'password' To protect against this, we strongly recommend that you create a specific MS SQL user with restricted permissions. Grafana doesn’t validate that a query is safe, and could include any SQL statement.įor example, Microsoft SQL Server would execute destructive queries like DELETE FROM user and DROP TABLE user if the querying user has permission to do so. The Connection timeout setting defines the maximum number of seconds to wait for a connection to the database before timing out. You can also override this setting in a dashboard panel under its data source options. We recommend setting this value to match your Microsoft SQL Server write frequency.įor example, use 1m if Microsoft SQL Server writes data every minute. This value must be formatted as a number followed by a valid time identifier: Identifier The Min time interval setting defines a lower limit for the $_interval and $_interval_ms variables. These options are described in the sections below. ![]() You can also configure settings specific to the Microsoft SQL Server data source. Sets the maximum number of seconds that the data source can reuse a connection. If set will set the maximum number of idle connections to the number of maximum open connections (Grafana v9.5.1+). ![]() Sets the maximum number of connections in the idle connection pool. Sets the maximum number of open connections to the database. Sets the authentication mode, either using SQL Server Authentication or Windows Authentication (single sign-on for Windows users).ĭetermines whether to negotiate a secure SSL TCP/IP connection with the server, or to which extent. You can specify multiple connection properties, such as ApplicationIntent, by separating each property with a semicolon ( ). Sets the IP address/hostname and optional port of your MS SQL instance. Sets the data source that’s pre-selected for new panels. Sets the name you use to refer to the data source in panels and queries. Set the data source’s basic configuration options: The Settings tab of the data source is displayed. Under Your connections, click Data sources.Įnter Microsoft SQL Server in the search bar. To configure basic settings for the data source, complete the following steps: Once you’ve added the Microsoft SQL Server data source, you can configure it so that your Grafana instance’s users can create queries in its query editor when they build dashboards and use Explore. Only users with the organization administrator role can add data sources.Īdministrators can also configure the data source via YAML with Grafana’s provisioning system. This topic explains configuration specific to the Microsoft SQL Server data source.įor instructions on how to add a data source to Grafana, refer to the administration documentation. You can query and visualize data from any Microsoft SQL Server 2005 or newer, including Microsoft Azure SQL Database. Grafana ships with built-in support for Microsoft SQL Server (MS SQL).
