>
> There are many factors which can influence the response rate of the REST API
> when the web client polls various endpoints:
> - Database access problems
> - Federated PropertyProvider delays
> - Serialization Time of JSON
> If the response rate of the REST API is poor, this can affect the overall UX
> of the product and produce a situation where Ambari doesn't seem to be
> responding.
> There should be an alert which provides queries into various parts of Ambari
> in order to determine if response times are acceptable.
> - This should be a {{SERVER}} side task
> - If possible, the query should be made directly through the ResourceProvider
> framework to simulate a REST request. It should be made against the cluster
> endpoint since that's what is most likely polled.
> - The alert should have configurable values for the threshold settings.
