[syslog-ng] syslog-ng premium "$HOST" issue

Hi, I am using syslog-ng opensource version 1.6.5 on central syslog server. which is receiving logs from 4 collectors and some individual hosts. To evaluate syslog-ng premium I got 30 day license of "syslog-ng-premium-edition 3.0.2a" and installed it on a new box. and forward events coming on central syslog server to this new box using a file template template("'$HOST'|'$FACILITY'|'$PRIORITY'|'$PROGRAM'|'$MONTH $DAY$ $YEAR $HOUR:$MIN:$SEC'|'$MSGONLY'\n")); but here in $HOST I am getting name of central syslog server instead of actual host. While in ver 1.6.5 it appears correct using same template on events coming from 4 collectors. is there version incompatibility or some bug in ver 3.0.2a Regards, -Manish
