Mark Payne commented on NIFI-3065:
----------------------------------
Re-opening issue because I encountered a bug that I think needs to be addressed
before this is included.
If I have a Process Group that has no Log File Suffix configured, and I then
copy & paste the PG, the new one has the Log File Suffix configured with a
value of "Copy_of_". This means that every time a PG is copied and pasted, it
will create a new log file, and it will be difficult to understand what is
happening.
> Fine-grained logging in multi-tenant context

> Project: Apache NiFi

> Components: Core Framework
> Reporter: Pierre Villard

> In a multi-tenant approach, it could be interesting to offer to users a way
> to have a fine-grained logging capabilities per tenant.
> Let's say that root process group is used to have one process group per
> "project" accessed by different teams/users, it could be really useful to
> have a log file per process group containing logs for all elements inside
> this process group.
> A first version could be to develop a custom log appender that would log each
> message in a file dedicated to its process group parent.
> This improvement will ease the logging management when there are hundreds of
> processors separated between different teams and this will also prevent the
> access to the logs concerning one team by another team (could be a security
> issue).
