[rsyslog] How to test rsyslog performance

[Sayan Chowdhury]

Hi,
I saw the announcement of the 4.2.0 stable version of rsyslog. I was
wondering if there is a way I can test the performance of rsyslog with my
own rsyslog.conf.
The way I am trying to use rsyslog is on a local system, which has following
rules

logging different facilities to different files with different formats.
forwarding certain facilities to an external server.
receive messages from one(and only one) other machine over udp.

Are there any tool/scripts available which I can use to perform the tests
myself?
Basically what I am thinking of is running a script which writes is bunch of
messages to syslog, but then how do I make sure all those messages were
actually logged and not lost? It may be very painful to look through the
entire log file 1 message at a time :)
Is there a stat/counter based api which shows me how many messages were
logged?

Regards,
Sayan
