[syslog-ng] Injecting environment variables?

[jetjnkr at gmail.com]

Balazs,

Thanks,  do you have any examples in using the backtick it in a message template?  Do you have to assign it to a config variable in a "define" first?

How much 'earlier' versions of syslog-ng  will this work (e.g. before 3.2 ?)

Jim.
