Version 6.1.0  [DEVEL] (rgerhards), 2010-08-12

*********************************** NOTE **********************************

The v6 versions of rsyslog feature a greatly redesigned config system which, among others, supports scoping. However, the initial version does not contain the whole new system. Rather it will evolve. So it is expected that interfaces, even new ones, break during the initial 6.x.y releases.

*********************************** NOTE **********************************

  • added $Begin, $End and $ScriptScoping config scope statments(at this time for actions only).
  • added imptcp, a simplified, Linux-specific and potentielly fastsyslog plain tcp input plugin (NOT supporting TLS!)

rsyslog 5.5.6 (devel) released

adisconteamNews, Release Announcement, ,

Hi all,

We have just released rsyslog 5.5.6, a member of the devel branch.

The new release provides exciting performance enhancements: on multicore-machines it can be many times faster than version 5.5.5 (which already was quite fast). Most importantly, the enhancement provides much better scalability, so adding many additional core gains much more speedup than with any previous version.

A new concept of “strgen” modules has been implemented, which permit to use high speed C code as templates. Also, support for malformed “last message repated n times” messages, as emited by some syslogds, has been added in form of a custom message parser.

There are also a couple of bugfixes and minor improvements.

See ChangeLog for more details.

As always, feedback is appreciated.

Best regards,

Version 5.5.6  [DEVEL] (rgerhards), 2010-07-21

  • added parser modules
    • pmlastmsg, which supports the notoriously malformed “last message repeated n times” messages from some syslogd’s (namely sysklogd)
    • pmrfc3164sd (contributed), supports RFC5424 structured data in RFC3164 messages [untested]
  • added new module type “string generator”, used to speed up output processing. Expected speedup for (typical) rsyslog processing is roughly 5 to 6 percent compared to using string-based templates.
    They may also be used to do more complex formatting with custom C code, what provided greater flexibility and probably far higher speed, for example if using multiple regular expressions within a template.
  • added 4 string generators for
    • RSYSLOG_FileFormat
    • RSYSLOG_TraditionalFileFormat
    • RSYSLOG_ForwardFormat
    • RSYSLOG_TraditionalForwardFormat
  • bugfix: mutexes used to simulate atomic instructions were not destructed
  • bugfix: regression caused more locking action in msg.c than necessary
  • bugfix: “$ActionExecOnlyWhenPreviousIsSuspended on” was broken
  • bugfix: segfault on HUP when “HUPIsRestart” was set to “on” thanks varmojfekoj for the patch
  • bugfix: default for $OMFileFlushOnTXEnd was wrong (“off”).

This, in default mode, caused buffered writing to be used, what means that it looked like no output were written or partial lines. Thanks to Michael Biebl for pointing out this bug.
