------------------------------
Assignee: Anna Nys
> 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: 1.11.4, 1.13.2
> Reporter: Nissim Shiman
> Assignee: Anna Nys
> Priority: Major
>
> "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.
