I saw `substr($fromhost-ip,0,5)` example in the lookup_table functions' offical document. But I can't find any documents about `substr` function self.
When I use substr in my rsyslog.conf, the `rsyslogd -N1` testing command return OK, but the result string always be null(""). So, is it a wrong example ,or an un-implement function now? _______________________________________________ rsyslog mailing list http://lists.adiscon.net/mailman/listinfo/rsyslog http://www.rsyslog.com/professional-services/ What's up with rsyslog?
