Changelog for 7.3.1 (v7-devel)

By Adiscon SupportPosted on Posted in ChangelogTagged , , , , , , ,

Version 7.3.1  [devel] 2012-10-19

  • optimized template processing performance, especially for $NOW family of properties
  • change lumberjack cookie to “@cee:” from “@cee: ”
    CEE originally specified the cookie with SP, whereas other lumberjack tools used it without space. In order to keep interop with lumberjack, we now use the cookie without space as well. I hope this can be changed in CEE as well when it is released at a later time.
    Thanks to Miloslav Trmač for pointing this out and a similiar v7 patch.
  • bugfix: imuxsock and imklog truncated head of received message
    This happened only under some circumstances. Thanks to Marius
    Tomaschwesky, Florian Piekert and Milan Bartos for their help in solving this issue.
  • bugfix: imuxsock did not properly honor $LocalHostIPIF

Changelog for 6.5.1 (v6-beta)

By adisconteamPosted on Posted in ChangelogTagged , , , , , , , , , , , , , ,

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

By adisconteamPosted on Posted in News, Release AnnouncementTagged , , , , , , , , , , , , ,

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

By Rainer GerhardsPosted on Posted in FAQTagged , , , , , , , , , , , , , , ,

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.

Changelog for 5.9.4 (v5-devel)

By Adiscon SupportPosted on Posted in ChangelogTagged , , , , , , ,

Version 5.9.4 [V5-DEVEL], 2011-11-29

  • imuxsock: added capability to “annotate” messages with “trusted information”, which contains some properties obtained from the system and as such is sure to not be faked. This is inspired by the similiar idea introduced in systemd. removed dependency on gcrypt for recently-enough GnuTLS
    see: http://bugzilla.adiscon.com/show_bug.cgi?id=289
  • bugfix: imuxsock did no longer ignore message-provided timestamp, if so configured (the *default*). Lead to no longer sub-second timestamps.
    closes: http://bugzilla.adiscon.com/show_bug.cgi?id=281
  • bugfix: omfile returns fatal error code for things that go really wrong previously, RS_RET_RESUME was returned, which lead to a loop inside the rule engine as omfile could not really recover.
  • bugfix: rsyslogd -v always said 64 atomics were not present
    thanks to mono_matsuko for the patch
