Have setup various filters like below
Snip from rsyslog.conf
$template mytestFile,"/var/log/testlog/%$YEAR%-%$MONTH%-%$DAY%/%HOSTNAME%.log"
#
if ($fromhost contains 'mytest') then {
$FileCreateMode 0644
*.* ?mytestFile
}
#
if ($fromhost contains 'nettools') then
*.info;mail.none;authpriv.none;cron.none /var/log/messages
# The authpriv file has restricted access.
authpriv.* /var/log/secure
# Log all the mail messages in one place.
mail.* -/var/log/maillog
# Log cron stuff
cron.* /var/log/cron
# Everybody gets emergency messages
#*.emerg *
# Save news errors of level crit and higher in a special file.
uucp,news.crit /var/log/spooler
# Save boot messages also to boot.log
local7.* /var/log/boot.log
Now my requirement if anything did't matched in above filters then only that should redirect to /var/log/messages .
