      Table 1 Basic information

      Parameter	Description
      Name	Name of a filter. Each name must be unique. Enter up to 255 characters and do not start or end with an underscore (_). Only digits, letters, and underscores are allowed.

      Description	(Optional) Description of the filter. Enter up to 1,000 characters.
      Type	Type of the filter. Select Custom variable. You can set static or dynamic variable values and use them in query statements for batch statement modification.

   2. (Optional) Configure a static variable value for the filter of the custom variable type.
      1. Click Add Static Variable Value in the Static Variable Value area.
      2. Configure a static variable by referring to the following table.

         Table 2 Static variable configuration

         Parameter	Description
         Value	Field value of the static variable. Enter up to 255 characters and do not start or end with an underscore (_). Only digits, letters, and underscores are allowed.
         Alias	(Optional) Alias of the field value of the static variable. Enter up to 64 characters. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. Do not start with a period or underscore or end with a period. After an alias is set, it will be displayed preferentially.
         Default Value	Whether to use the value of the static variable as the default value. (If an alias has been set, the alias will be displayed preferentially.): Enable: The value of the static variable is automatically selected as the default value of the filter. Disable: The value of the static variable is not automatically selected as the default value of the filter.

         To delete a static variable value, click Delete in the Operation column.

   3. (Optional) Configure a dynamic variable value for the filter of the custom variable type.
      1. Toggle on Dynamic Variable Value.
      2. Configure the source of the dynamic variable value:
         • Prometheus instance: Query dynamic variable values from a Prometheus instance.
      3. Configure dynamic variable parameters.
         • When Dynamic Variable Value Source is set to Prometheus instance, set parameters by referring to the following table.

           Table 3 Dynamic variable configuration (source: Prometheus instance)

           Parameter	Description
           Prometheus instance	Prometheus instance from which dynamic variable values are queried. By default, the Prometheus instance selected in the upper left corner after you access the dashboard details page is used. This parameter is grayed here and cannot be selected. To change the Prometheus instance, select another Prometheus instance on the dashboard details page.
           Query Method	Option: Metric field match.
           Metric Name	Select a metric under the selected Prometheus instance.
           Variable Display Field	Select a field of the metric to display. The values corresponding to this field will be displayed in the dashboard filter drop-down list. Example: If this parameter is set to Cluster Name, specific cluster names will be displayed in the dashboard filter drop-down list.
           Variable Value Field	Select an actual field for filtering. For example, if Variable Display Field is set to Cluster Name and Variable Value Field is set to Cluster ID, when you select a cluster name from the dashboard filter drop-down list, the actual cluster ID will be used as the criterion for filtering.
           Filter Criteria	Configure a dimension name and value. The = and != operators are supported. You can click to use AND to set multiple filter criteria for the same metric.
           Sort By	Configure how the options will be displayed in the dashboard filter drop-down list. Option: None.

   4. Configure other information about the filter of the custom variable type.
      • Default Value: Configure the default value of the filter. You can select the static or dynamic variable values configured in 2 or 3.
      • Multi-Option Allowed: Whether multiple options can be selected for the filter. This function is enabled by default. After this function is enabled, multiple options are selectable for the filter.
      • Include "Select All": Whether the Select All option is available in the drop-down list. This function is enabled by default. After this function is enabled, the Select All option is selectable.
   5. Click Preview to preview your filter settings.

6. Click OK to create a filter of the custom variable type.

   The new filter is displayed on the dashboard details page and the page for adding a graph. You can click the filter and enter a criterion in the search box or select a criterion from the drop-down list to filter statistical graphs in a dashboard.
