are these two different configs (the sender and the receiver)?
a simple way to see the message rate is to do a
cut -f 1 -d ' ' logfiles |sort |uniq -c
to look at the timestamps and see how many timestamps you have in a second.

What's a good way to look at message ratE?

Sorry. I wasn't real clear. The server runs on a big VM in another
location
completely. No issues with the server during this time. This has been an
ongoing thing. I'm running Splunk on the same box and if I turn off
rsyslog
and turn splunk on the same port it gets all the messages that don't seem
to get picked up by rsyslog.
Doesn't appear to be any rate limiting configuration.
Ok, that is a different situation. In my experience, rsyslog is
signicantly better than Splunk at receiving messages. I've testing rsyslog
up to 380K messages/sec (gige wire speed) and others have tested rsyslog up
to 1M messages/sec, so it's unlikely to be something fundamental to
rsyslog, but it could easily be some resource contraint you are running
into.
can you post your full configuration?
what message rate are you seeing?
