-----------------------------------
Summary: Visual Status and Troubleshooting Tool
Key: NIFI-3558
URL: https://issues.apache.org/jira/browse/NIFI-3558
Project: Apache NiFi
Issue Type: New Feature
Components: Core Framework, Core UI
Reporter: Andy LoPresto
There has been intermittent discussion on the mailing list of a visual status
dashboard and troubleshooting tool to bring the institutional knowledge of the
entire community closer to the end user. The mailing lists frequently receive
the same classes of question (thread starvation, open file handles, heap size,
etc.) and the users have to wait for another community member to ask a series
of questions and manually diagnose the issue. Few users comprehensively read
the Admin Guide or Best Practices documents, and quickly identifying possible
issues that are easily fixed will improve the user experience and reduce the
unnecessary strain on the mailing lists.
Use this ticket to collect suggested issue/configuration identification,
messaging, suggested solutions, and thoughts about how to display this
information in a digestible manner to the users.
Example from Peter Wicks:

In my case I had not seen the issue until I added 7 new
QueryDatabaseProcessor's. All seven of them kicked off against the same SQL
database on restart and took 10 to 15 minutes to come back. During that time
my default 10 threads was running with only 3 to spare, which were being shared
across a lot of other jobs. I bumped it up considerably and have not had
issues since then.
