thks
but i want the change bee sent in (real time) if we can use this term
because follow_freq(1) means that syslog need to check tchangee in the fie every 1 second
is there any way to make it 0 second ====> detect changes in the apache error log as they happen
thks

Since you are using 2.0, you need to explicitly specify for syslog-ng
that you want to poll the file for changes. You can do this via the
follow-freq() option, e.g.

file("/var/log/apache2/error_log" follow_freq(1));

In 3.0, the default value for follow_freq() for regular files is 1
seconds, so you wouldn't have to specify it explicitly.
