Wildcard support for InputFileName in rsyslog?
Ive done some research on this in the past. As of the last time i checked the imfile module doesn't support wildcards at all. Thought about possibly writing another input module but ended up just using syslog-ng on the hosts I need this functionality on.
As an update to this post rsyslog 8.5 (currently development but soon to be stable) does support wildcards, I've tested this and can confirm it is working.
