# Custom measure
If you decided to use a custom measure / KPI that is not part of the basic ProcessMining KPI’s, this is where you can format the custom KPI.
You can set the measure format. Basically this is the representation of the measure. You can set the default aggregation type (like SUM, Average, MIJ or MAX) and add prefixes or suffixes to the measure being shown in your process map (on either Paths or activities)
The example below shows a custom measure that is formatted as Time (in seconds). The extension will automatically use the time hierarchy to represent a logical representation.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.infotopics.com/processmining/features/custom-measure.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
