This more in-depth discussion has more value. Thank you.
I think that RELP and on-demand disk spooling of messages are compelling features
I think we're coming at the question from different perspectives. One of my primary goals is to avoid wasting my time. Since I've already evaluated and experimentally proven syslog-ng, switching means a large time investment.
As such, features like REPL and, arguably misfeatures[1], like disk spooling, fail to compel such an investment.
Once rsyslog has matured, something that I expect will be accelerated by its inclusion in major distros, it may be a no-brainer.
For my "money," there are far more interesting and productive problems to work on than logging, which is why I do give the "just use it" advice.
Turns out I am a sysadmin as well
By choice or necessity? Just curiosity on my part.
[1] I have yet to encounter an environment of non-trivial size where the risk of losing logging outweighs the risk of disk filling up and/or performance degradation from additional contentious I/O. For me, it's a killer feature of centralized logging: elimination of a particular source of failure/degradation.
