I want to read a file which is in the name of the IP of syslog-ng client machine I tried with $HOST macro

But this does not work Any help on doing this ?
I guess the file() source doesn't expand templates, so it actually tries to open a file called "/mnt/$HOST" (literally). If you're using relatively recent version of syslog-ng (starting 3.2 I *think*) you should be able to achieve this however using environmental variables (see chapter 5.6 from the v3.6 guide): | source { file (/mnt/`HOSTNAME`); }; This would only work of course if HOSTNAME is exported when running syslog-ng
