[rsyslog] omfile redesign / $OutChannel will go away!

[Sayan Chowdhury]

Hello Rainer,

I do use this facility. This is how I do it

$outchannel log_rotation_16,/var/private/log/logsip,
10000000,/opt/platform/bin/log_rotate.pl

if $syslogfacility == '16' and $syslogseverity <= '6' then
$log_rotation_16;precise

The log_rotate.pl perl script that I have rotates the files
and maintains a set of 10 files. When the current file reaches the 10 mb
limit, the older file is zipped and copied over to a different directory.
I am on release 3.21 now

I would definitely like to have the feature be present in the future
releases as well. I am happy as long as this feature of file size based
rotation is there and I can migrate my rules/scripts to whatever new
mechanism that get implemented.

Regards,
Sayan
