Rate your experience required. Comments required. Instead of hard-coding details such as server, application, and sensor names in metric queries, you can use variables. Grafana lists these variables in dropdown select boxes at the top of the dashboard to help you change the data displayed in your dashboard. Grafana refers to such variables as template variables. For an introduction to templating and template variables, refer to the Templating and Add and manage variables documentation. For details, refer to the Graphite docs on the autocomplete API for tags.

Query variables enable you to write a data source query that can return a list of metric names, tag values, or keys. For example, a query variable might return a list of server names, sensor IDs, or data centers. The variable values change as they dynamically fetch options with a data source query. Query variables are generally only supported for strings. If your query returns numbers or any other data type, you might need to convert them to strings in order to use them as variables. For the Azure data source, for example, you can use the tostring function for this purpose. Query expressions can contain references to other variables and in effect create linked variables. Grafana detects this and automatically refreshes a variable when one of its linked variables change. Note: Query expressions are different for each data source. For more information, refer to the documentation for your data source. For example, if you have server names or region names that never change, then you might want to create them as custom variables rather than query variables.

Export alerting resources. The formatting of the variable interpolation depends on the data source, but there are some situations where you might want to change the default formatting. Loki Configure Loki. Provision Alerting resources Use configuration files to provision. In this case, every value must be escaped so that the value only contains lucene control words and quotation marks. If not, a value with a regex control character would break the regex expression. Note The Custom all value option on the variable must be blank for Grafana to format all values into a single string. Filters you apply in this manner are applied to all panels on the dashboard.

After a brief acquaintance with Grafana in sandboxes, production application developers come to the need to work with variables serving different architectural levels. This article outlines three logical levels with corresponding variables and their purposes. Dashboard variables serve the analytical dashboards, and global Grafana variables rule in the Grafana instance.
