--------------------------------
Summary: Add an Analysis section to the Processor Diagnostics
Key: NIFI-4852
URL: https://issues.apache.org/jira/browse/NIFI-4852
Project: Apache NiFi
Issue Type: Sub-task
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
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.
