[syslog-ng] Example 3.4. Script to feed a growing logfile into syslog-ng

Followed http://www.syslog.org/syslog-ng/v2/#id2535001 and created some tail logger combos to feed some growing logfiles into syslog-ng. Issue that I am need to get around is that while I haven't missed capturing any messages this way the time stamps in syslog-ng seem to be when logger actually gets the line into syslog rather than that of the tailed files line. I have a very quick-filling file (logged 143 messages yesterday all at 14:15:18) and when I view syslog-ng these are stamped up to 14:15:36 and no longer in any order. Does anyone have any suggestions? Thanks.
