You can open the editor of any system or custom indicator to check its settings and edit its definition and metadata in order to adapt it to a specific database type or need, if required.

3. Modify the indicator metadata, if required.
4. In the Indicator Category view, select an indicator category from the list:
   | Indicator category | Description |
   | --- | --- |
   | User-defined Match (by-default category) | Uses custom indicators to evaluate the number of the data records<br>that match a regular expression or a SQL pattern. The analysis results show the<br>record matching count and the record total count. |
   | User-defined Frequency | Uses custom indicators for each distinct data record to evaluate the<br>record frequency that match a regular expression or a SQL pattern. The analysis<br>results show the distinct count giving a label and a label-related<br>count. |
   | User-defined Real Value | Uses custom indicators which return real value to evaluate any real<br>function of the data. |
   | User-defined Count | Uses custom indicators that return a row count. |

   If you change the indicator category, you can keep the existing indicator definition or remove the indicator definitions for all databases but the one for Java.
5. In the Indicator Definition view, set the indicator definition for one or more databases using ![Add](https://help.qlik.com/talend/en-US/studio-user-guide/Resources/images/add.svg).

   If the indicator is simple enough to be used in all databases, select Default in the list.
6. In the Indicator Parameter view, modify the indicator parameters as needed.
