1. Go to **Monitoring > Requests Profiles** .

1. In the **Requests Profiles** section, copy the token.
1. Pass the headers `X-Profile-Token: <token>` and `X-Profile-Mode: <mode>` (where
`<mode>` can be `execution` or `memory` ) to the request you want to profile. When
passing headers, you can use:
- Browser extensions such as the
[ModHeader ](https://chrome.google.com/webstore/detail/modheader/idgpnmonknjnojddfkpgkljpfnnfcklj )
Chrome extension.
- `curl` . For example:
```shell
curl --header 'X-Profile-Token: < token > ' --header 'X-Profile-Mode: < mode > ' "https://gitlab.example.com/group/project"
```
Profiled requests can take longer than usual.
After the request completes, you can view the profiling output from the
