paul wright Usage is similar to all SDK's

Android:

MobileCore.getInstance().getServiceById("userSpecifiedId");

IOS:

AgsCore.instance.getConfigurationById("userSpecifiedId");

JS:
I will need to confirm that with Wei, it will be:

let app = require("@aerogear/app")

app.getConfigurationById("userSpecifiedId");

// or

let core = require("@aerogear/core")

core.INSTANCE.getConfigurationById("userSpecifiedId");

Xamarin

MobileCore.Instance.GetServiceConfigurationById()

> can you confirm that this is valid for monitoring custom connector service:

Do not feel competent enough to answer that question correctly, but...
I haven't heard about any requirements to support custom runtime connector metrics.
We were asked to hide metrics from end users in SDK's so linked document may be just for internal needs and it should not be visible to users.
David Martin or Peter Braun may confirm.
