# Configuration

## Appmixer Engine

#### APP\_NAME

The authentication popup windows do contain the *Appmixer* title by default. If you want to change that, set the APP\_NAME env variable in the Appmixer engine.

![](/files/-MXrRuoQJ1D7IN3KTBwf)

Example from the docker-compose.yml

```
  engine:
    ...
    environment:
      - APP_NAME=ACME
    ...
```

#### LOG\_LEVEL

By default set to `info`. Can be changed to `error`, `warn` or `debug`.

#### LOG\_COMPONENT\_DATA\_MESSAGE

When set to `false`, the component's input/output messages won't be logged into Elasticsearch.

{% hint style="info" %}
Important! Appmixer Insights and Designer log messages won't contain any items if logging data messages are turned off.
{% endhint %}

#### APPMIXER\_HTTPS\_PROXY and APPMIXER\_HTTP\_PROXY

Setup proxy using these ENV variables. All HTTP(S) requests from Appmixer will be redirected to the proxy URL.
