Hi Joe and David, thanks for your persistence. I have just committed a new version that supports a "statistics subsystem":
http://git.adiscon.com/?p=rsyslog.git;a=commitdiff;h=e86cb62f1299ef18732f7b3b 87d45a840ee38f1e It is not a big system, but contains a counter registry and the necessary plumbing to define simple counters. So far, I have implemented a counter for the number of messages received by imuxsock, and for the queue current queue size, max queue size ever and how often the queue was full. Of course, these are demo counters and others can (and will) be added. They all fall into the "easy to obtain" category, done with atomic instructions where available. Counters are always present, but are maintained only when impstats is loaded. So the performance toll should be minimal when not in use. I still plan to add a configure option to turn off stats at all (for very high-end environments). I hope to have this as a official release soon. Feedback on the current status is appreciated.
