> 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
