RSyslog Documentation




Like the OS call, returns the value of the environment variable, if it exists. Returns an empty string if it does not exist.


The following example can be used to build a dynamic filter based on some environment variable:

if $msg contains getenv('TRIGGERVAR') then /path/to/errfile
