I think if Nginx only updated counters (similar to OpenVZ's bean
counters) this would not be an issue and would work well with the shared
memory/virtual file approach (and fits better with the idea of event
monitoring vs logging/post-mortem). Rather than a stream of data you
have a "file" of fixed size that's constantly updated. It also
simplifies the parsing of the data by an external application.
If a virtual file system (like /proc) were used, then it should also be
possible to use inotify (or similar) from external apps to be notified
of events (although this might be too busy).
