Same Hello here ;)
did have a more in depth look in the manual and figured out that
varnishncsa does support VSL query.
so someone could filter on the Request Header and Host
varnishncsa -q "ReqHeader ~ '^Host: .*example.com'"
which would produce a log for a specific domain only
it then would need multiple varnishncsa instances for logging per
domain, which I found here:
https://kevops.com/2015/11/varnish-logging-per-host-with-init-script/
I use varnish version 5 and then there would be no need for splitlog and
the logs would be created directly.
please correct me if I'm wrong?
thanks for your time & help

Hello again,
My apologies for not explaining my thoughts better earlier then. Afaik,
varnishncsa does not have a native method to split output based on
different parameters. The method I was thinking of was based on piping
varnishncsa output through splitlogs (or similar) for the log processing
and writeouts. Since replying earlier, I've got this working on a cPanel
server with piped logging enabled for Apache using the following two for
example (X-Port is a custom header set in vcl_recv related to SSL
offloading, but you can use a static value or similar custom header):
varnishncsa -F "%{HOST}i:%{X-Port}i %h %l %u %t \"%m %U%q %H\" %s %b
\"%{Referer}i\" \"%{User-agent}i\""|sed -e
's#^www\.##g'|/usr/local/cpanel/bin/splitlogs --main=`hostname`
--mainout=/usr/local/apache/logs/access_log
varnishncsa -F "%{HOST}i %{%s}t %b ."|sed -e
's#^www\.##g'|/usr/local/cpanel/bin/splitlogs --main=`hostname`
--suffix=-bytes_log
The above pipes the requests to the splitlogs binary which queues then
writes to separate logs per domain, that are later processed by the
cPanel log stats apps. Either way, I believe you need an intermediary
script to queue and write the log entries per domain. While looking into
this process, I ran across this little tidbit which you may find of use
https://gist.github.com/garlandkr/4954272 for logstash style output.
