Review request for Ambari, Alejandro Fernandez, Dmitro Lisnichenko, and Nate
Cole.
Bugs: AMBARI-15745
https://issues.apache.org/jira/browse/AMBARI-15745
Repository: ambari
Description
-------
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.
