+# Google Cloud Monitoring template variables
+
+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]({{< relref "../../../dashboards/variables" >}}) and [Add and manage variables]({{< relref "../../../dashboards/variables/add-template-variables" >}}) documentation.
+
+## Use query variables
+
+Variables of the type _Query_ help you query Google Cloud Monitoring for various types of data.
+The Google Cloud Monitoring data source plugin provides the following **Query Types**:
+
+| Name                               | List returned                                                         |
+| ---------------------------------- | --------------------------------------------------------------------- |
+| **Metric Types**                   | Metric type names available for the specified service.                |
+| **Labels Keys**                    | Keys for `metric label` and `resource label` in the specified metric. |
+| **Labels Values**                  | Values for the label in the specified metric.                         |
+| **Resource Types**                 | Resource types for the specified metric.                              |
+| **Aggregations**                   | Aggregations (cross-series reducers) for the specified metric.        |
+| **Aligners**                       | Aligners (per-series aligners) for the specified metric.              |
+| **Alignment periods**              | All alignment periods available in the query editor in Grafana.       |
+| **Selectors**                      | Selectors for SLO (Service Level Objectives) queries.                 |
+| **SLO Services**                   | Service Monitoring services for SLO queries.                          |
+| **Service Level Objectives (SLO)** | SLOs for the specified SLO service.                                   |
+
+## Use variables in queries
+
+Use Grafana's variable syntax to include variables in queries.
+For details, refer to the [variable syntax documentation]({{< relref "../../../dashboards/variables/variable-syntax" >}}).
