[syslog-ng]"last message repeated NN times"?

[Ed Ravin]

I recall someone pointing out last year that syslogd has a feature
where it can compress a burst of messages into a note like:

  Jan 10 17:01:06 loghost last message repeated 24 times

While syslog-ng didn't have that.  Is that still the case?  I just
ran into this with a mongo runaway program that logged several hundred
messages a second, which filled up my log partition.

If this feature still isn't in syslog-ng, is it one that we want?  I could
see it as a source option like "suppress-repeats", where it would spit out
the original message followed by a tag, like this:

  Jan 10 17:25:39 loghost inetd[7729]: Connection from 10.24.1.168 [REPEATED 1024 TIMES]

and maybe arguments to "suppress-repeats" like how many repeats should be
printed before kicking in, or perhaps even a regex describing which parts
of the log message to ignore before comparing it to the previous one.

Thanks,
