@trixpan I modified the documentation as you suggest even though I do have
use cases where the appended file is static and rolling files contain the date.
I think you can give it a try... it may need a bit a polishing but it should
work. I tried to stay as close as possible to the original implementation, let
me know how it behaves when dealing with huge files :)
> TailFile "File to Tail" property should support Wildcards

> Key: NIFI-1170
> URL: https://issues.apache.org/jira/browse/NIFI-1170
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 0.4.0
> Reporter: Andre
>
> Because of challenges around log rotation of high volume syslog and app
> producers, it is customary to logging platform developers to promote file
> variables based file names such as DynaFiles (rsyslog), Macros(syslog-ng)as
> alternatives to getting SIGHUPs being sent to the syslog daemon upon every
> file rotation.
> (To certain extent, used even NiFi's has similar patterns, like for example,
> when one uses Expression Language to set PutHDFS destination file).
> The current TailFile strategy suggests rotation patterns like:
> {code}
> log_folder/app.log
> log_folder/app.log.1
> log_folder/app.log.2
> log_folder/app.log.3
> {code}
> It is possible to fool the system to accept wildcards by simply using a
> strategy like:
> {code}
> log_folder/test1
> log_folder/server1
> log_folder/server2
> log_folder/server3
> {code}
> And configure *Rolling Filename Pattern* to * but it feels like a hack,
> rather than catering for an ever increasingly prevalent use case
> (DynaFile/macros/etc).
> It would be great if instead, TailFile had the ability to use wildcards on
> File to Tail property
