Creating Filters

Dexda has a common filter component to define a query filter consistently across functionality like charts, rules, and actions. When building queries and aggregations to limit results, you have a set of fields to choose from. Available fields vary depending on the input from the selected data source – events, alerts, or insights.

Procedure

1. Under Filter, select Add expression. You can see the pop-up fields to select fields, select a logical operator, and enter a value.
2. Select a desired field to be filtered. In the Select field, you will see a list of record types. For more information, see Filter Fields.
3. Select an operator such as contains, equals, in, and so on. For more information, see Filter Operators.
4. Based on the previous selections, you might enter an appropriate value. For instance, when you select Not empty as an operator, you will not have an option to enter a value. However, when you choose the field as State, and the operator as In, you can enter a list of alert states such as closed, open, and cleared.
5. Select Add to add the filter. By default, this filter will be in an And node on top of the filter.
6. Select the fork icon to create another filter node, and select the filter icon. You can choose to change the nodes of all filters as And or Or.
7. Repeat steps 2 to 5 to add filters as necessary.
