* ### **Set Log Level:**
* * This dialog is applicable only for Application logs. There are 4 log levels. ERROR, INFO, DEBUG and VERBOSE.
* DEBUG level is typically used to debug issues.
* ERROR level will only log if there are errors.
* VERBOSE is currently not used, but will log all the other log levels. In other words, currently DEBUG and VERBOSE levels log the same logs.
* Default is INFO. INFO level is recommended since this will log important user activities like login, logout, key creation, import, sending keys to terminal etc.
* These logs are needed for compliance.
* ### **Logout**
* This option logs off and takes the user back to start screen

## 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.verifone.com/kld/kld-user-guide/user-guide-p400/verifone-kld-ui-description/main-menu.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.
