Description

Adding this ability to generate a Diagnostics Report will be very powerful in and of itself, as it can generate a lot of raw data about the internal state of NiFi, which can be used to diagnose a range of problems. However, it will result in quite a lot of data being generated, especially for a cluster that has several nodes.

There are common (perceived) problems that occur more frequently than others. For example, a user may think there is something wrong with a Processor because it is not processing the data in the incoming queue. Closer analysis may reveal that the Processor is only scheduled to run once every 1 second instead of the default of 0 seconds. Or the incoming queue may consist solely of penalized FlowFiles. In such a situation, it would be helpful if the Diagnostics Report were to contain an "Analysis" section that indicates when these sorts of common issues arise.
