-----------------------------------
Summary: Document difference between Active Threads as shown in
Status bar versus as shown by Node
Key: NIFI-8673
URL: https://issues.apache.org/jira/browse/NIFI-8673
Project: Apache NiFi
Issue Type: Improvement
Components: Documentation & Website
Affects Versions: 1.13.2, 1.11.4
Reporter: Nissim Shiman
"Active Threads" on the main gui's status bar has a lower number then "Active
Thread Count" when broken down by nodes
(i.e. Global Menu -> Cluster)
This is because "Active Threads" only captures threads by objects that are in
the graph (i.e. processors, processor groups, remote processor groups, funnels,
input and output ports). [1]
"Active Thread Count" is more comprehensive and includes these as well as any
other threads as well (i.e. reporting tasks, controller services etc.) [2] [3]
This difference should be documented in the Apache NiFi documentation.
