<p style="margin: 10px 0 0 0">I haven't thought through the cases yet but this is somewhat related to some issues I identified around our logging, and the need to look at probably adding some features like a "minimum" validity window in parallel to the maximum so that it starts warning loudly when metadata sources get "stuck".</p>
<p style="margin: 10px 0 0 0">I don't think there's any perfect answer and I'm not sure what Aaron specifically is attempting to detect, but it's likely more subtle than it appears at first glance. Obviously more information is usually better than less in any case.</p>
<p style="margin: 10px 0 0 0">As far as the API goes, we do have some "license" within the IdP if it's warranted to tunnel down into the implementation classes at times as a stopgap before 4.0. There's also the option to extend the instrumentation bits we're exposing. Right now the status page and metrics are outside in, but we might be able to reverse or supplement that.</p>
