Hi all,
I wonder what are the actual use cases behind the desire to have global
variables in rsyslog. There are two that I know (I describe them very
briefly as they were expressed at length in the past couple of days):
1. counting messages for some reason
2. load-balancing output actions
Number 2 is - I think - a weak one, as this should better go into a
specific facility inside the engine (read: nothing that the admin should
need to emulate in the conf file).
Are there any other *real-world* use cases?
I am asking because I would like to think if future development directions
of the rsyslog engine should consider the re-addition of global variable
support (which requires a major rewrite).
well, the original request that lead to getting global variables added was to
have the contents of one message set a variable that could be used in processing
future messages.
For this use, the current functionality works as-is.
