Re: CF app that helps with self-healing

Hjortshoj, Julian <Julian.Hjortshoj@...>

To me this seems a lot like a health check.  Is there some reason that you couldn't add a health check endpoint to your app instances (either directly, or as a sidecar) and then let CF take care of restarting the app instances for you?

Thanks Daniel J and Daniel M for your inputs.
Troy - We are also thinking something along those lines to see of we can use the App Autoscaler for the restarts.

Ideally you'd want to trace the application misbehavior to a root cause in the application itself, but I think we've all been in the situation where "turn it off and on again" is an easier solution. :)

I wonder if this could be a feature request for App-AutoScaler? It already has access to the metric types required for the operation, but it would need to be able to take a policy action based on those metrics other than scaling up or down (e.g. "adjustment" : "restart" ).
