## HTTP Trace

HTTP tracing can be enabled by using [`mc admin trace`](https://docs.min.io/community/minio-object-store/reference/minio-mc-admin/mc-admin-trace.html) command.

Example:

```sh
minio server /data
```

Default trace is succinct only to indicate the API operations being called and the HTTP response status.

```sh
mc admin trace myminio
```

To trace entire HTTP request

        assertEquals("bootstrap", RequestTrace.CONTEXT_BOOTSTRAP);
    }
