rsyslog 7.3.2 (v7-devel) released
This release introduced a totally new rate-limiting system for all modules as well as much better “last message repeated n times” handling. For details, please see Rainer’s blog at
http://blog.gerhards.net/2012/10/rate-limiting-in-rsyslog-732.html
Besides this feature, the version also includes enhancements for omelasticsearch as well as input batching support for imudp (which should provide some performance boost on very busy systems). Also, action-like statements (call, stop, …) are now supported in action lists. Of course, there are also some bugfixes, many imported from v6 and v7.2.

Changelog for 7.3.2 (v7-devel)
Version 7.3.2 [devel] 2012-10-30
- totally reworked ratelimiting and “last message repeated n times”
all over rsyslog code. Each of the supported inputs now supports
linux-like ratelimiting (formerly only imuxsock did). Also, the
“last message repeated n times” is now processed at the input side
and no longer at the output side of rsyslog processing. This
provides the basis for new future additions as well as usually more
performance and a much simpler output part (which can be even further
refactored). - imtcp: support for Linux-Type ratelimiting added
- imptcp: support for Linux-Type ratelimiting added
- imudp enhancements:
- support for input batching added (performance improvement)
- support for Linux-Type ratelimiting added
- permited action-like statements (stop, call, …) in action lists
- bugfix: segfault on startup when modules using MSG_PASSING mode are used
- omelasticsearch: support for writing data errors to local file added
- omelasticsearch: fix check for bulk processing status response

Changelog for 6.5.1 (v6-beta)
Version 6.5.1 [BETA] 2012-10-11
- added tool “logctl” to handle lumberjack logs in MongoDB
- imfile ported to new v6 config interface
- imfile now supports config parameter for maximum number of submits
which is a fine-tuning parameter in regard to input baching - added pure JSON output plugin parameter passing mode
- ommongodb now supports templates
- bugfix: imtcp could abort on exit due to invalid free()
- bugfix: remove invalid socket option call from imuxsock
Thanks to Cristian Ionescu-Idbohrn and Jonny Törnbom - bugfix: missing support for escape sequences in RainerScript
only \’ was supported. Now the usual set is supported. Note that v5
used \x as escape where x was any character (e.g. “\n” meant “n” and NOT
LF). This also means there is some incompatibility to v5 for well-know
sequences. Better break it now than later. - bugfix: small memory leaks in template() statements
these were one-time memory leaks during startup, so they did NOT grow
during runtime - bugfix: config validation run did not always return correct return state
- bugfix: config errors did not always cause statement to fail
This could lead to startup with invalid parameters.
rsyslog 6.5.1 (v6-beta) released
This is the new v6-beta, which includes the full v6-subset of the new config language as well as somewhat improved support for lumberjack/CEE. This version concludes development efforts for v6.
Note that it is recommended to use v7 if you do not have any special need for v6.

rsyslog statistics counter
Rsyslog supports statistic counters via the impstats module. It is important to know that impstats and friends only provides an infrastructure where core components and plugins can register statistics counter. This FAQ entry tries to describe all counters available, but please keep in mind that there may exist that we do not know about.
When interpreting rsyslog statistics, please keep in mind that statistics records are processed as regular syslog messages. As such, the statistics messages themselves increment counters when they are emitted via the regular syslog stream, which is the default (and so counters keep slowly increasing even if there is absolutely no other traffic). Also keep in mind that a busy rsyslog system is very dynamic. Most importantly, this means that the counters may not be 100% consistent, but some slight differences may exist. Avoiding such inconsistencies would be possible only at the price of a very tight locking discipline, which would cause serious performance bottlenecks. Thus, this is not done. Finally, though extremely unlikely, some counters may experience an overflow and restart at 0 for that reasons. However, most counters are 64-bit, so this is extremely unlikely. Those which are not 64 bit are typically taken from some internal data structure that uses lower bits for performance reasons and guards against overflow.
The listing starts with the core component or plugin that creates the counters and than specifies various counters that exist for the sub-entities. The listing below is extended as new counters are added. Some counters probably do not exist in older releases of rsyslog.
Below you can find all available core components and plugins. Please note that every core component or plugin are linked to a information site.
