Is there a way to set a proxy exception list within graylog after setting the http_proxy_uri option? It is better to use try and use the operating system’s proxy options?
No, that’s currently not possible.
You could try using the JVM proxy settings, which also feature an exclusion list via the http.nonProxyHosts system property:

Thanks. I will give that a try.
